Hello,

I wonder if anyone who uses Midinotate might have had an experience similar to the following. It is possible since midi playback is involved.

I installed Soundblaster Audigy 2 Zs. That went fine, and everything worked until I tried out playing a midi file. The instrument sound was very good, but there were frequent clicks and pops.

Assuming that there might be driver updates, I used Creative's auto-update to download and install the drives listed as critical and essential.

Wav and MP3 files acted as they should, but every time I try to play a midi file (whatever I use--Composer, Nero Media Player, Windows Media Player or Soundblaster's player--after a few to several seconds, a piercing buzz takes over and the computer freezes totally. The only option is to use the on/off button and wait out the disk scan on restarting.

I suspect there is something simple that I need to do, but I haven't found it after a lot of work. Can anybody make any suggestions?

many thanks,
mgj

Hello M.G.,

This probably doesn't happen for all of the MIDI device drivers that play through your SB Audigy soundcard. Which MIDI devices work and which don't work? These are the devices that are listed by MidiNotate's Setup / Quick MIDI Device Setup command.

Hi Mark,

You touch on something that is rather interesting. In the Audigy managers, in Control Panel\Sound, only SB Audigy 2 Zs Synth A (ECCO) and Synth B (ECCO) are given as choices for midi output devices and SB Audigy 2 Zs IO (ECCO) as the midi input device.

On the other hand Composer setup lists these, PLUS Microsoft GS Wavetable Sw Synth, SB Audigy 2 Zs Sw Synth (ECCO), and SB Live! Midi UART as an additonal IO External port.

But whichever device I set as default in either Windows Sound, Soundfont Bank Manager, or Composer, the buzz and lockup of the computer occur, whatever I use to play the file. (The choices, as I said, are limited to the A and B Synth for output in Windows and Audigy's SFBM.)

I've also had some odd things happen. After using Vienna Soundfont Editor for a half hour, with it working flawlessly, I got an access violation and it crashed (but not the computer) and the shortcut to it was grayed out and I could not start it from START\All Programs, until the next restart. Then WMP shut down all plug-ins because one was causing problems. The only new one is Nero's Fast CD Buring plugin.

I haven't tried setting Composer's default as the MS Wavetable or the Audigy Sw Synth. I'll do that now. If the crash occurs, perhpas I'll try the complete removal and see what a fresh installation from the CD with the card and the updates will do, or not do.

Hello again,

Well, I'm sure it makes sense to the computer's brain, but seem quirky and arbitrary to me, but not only did the MS Wavetable and the Audigy Sw Synth play, but those listed in SBFM, also. I haven't tried WMP or the Creative player yet.

The only thing I did, just before giving up a few hours ago, was to enable those annoying Windows sounds (as I remembered when I got a thunk when I released a slider in the SB mixer). I enabled them as part of a troubleshooting test and forgot to disable them again.

The only problem is that midi playback again sounds like a very well used old record, in terms of the pops, not the instrument sound. I have tried enabling/disabling/adjusting the graphic equalizer, EAX effects, etc., but can't get rid of them. Again, these pops are ONLY in midi playback, not wav or mp3.

all best,
mgj

Hi Mark and . . .

Well, a restart took care of the playing for more than a few seconds before total freeze. Since then I have uninstalled Windows Media Connect from the computer as well as removing Nero Fast CD Burner as a WMP plugin since I can't find how to uninstall just that. The midi playback worked with pops after both of those moves...until restarting.

I installed the Creative Media Source update and again midi played in Composer, WMP and Creative Media Player, with pops and until restarting.

I suppose that restarting seems to work the opposite of the way one might expect it to should tell me something, but I can't put my finger on what.

A complete wipe of anything from Creative (and maybe Nero, too), followed by reinstallation seems the next step, unless I can think of something better. There is one thing: the legacy audio drivers have Total Recorder as the playback driver for midi, but the only reference to this I can find is in Device Manager/Sounds, and there seems to be no option to change this. (I have changed Total Recorder to use SB Audigy 2 drivers, and TR still records fine).

It is not that the sound card won't work on the old Dell I have. I tried line in and my tape/cd player produces sounds I've never heard from its woofer or tweeters before--as if a baffle had been removed from in front of the orchestra. And wav and mp3 play excellently (and without the pops) in WMP and CMP.

It's just midi. Sigh....

If anybody can suggest what is eluding me about the restart killing any but a few seconds or midi playback before a crash, I'll try any idea at this point.

best,
mgj

Howdy MG,

Well, this may seem a silly question, and perhaps you've answered it above (but I didn't see it directly), but have you checked out the Advanced Properties in your Control Panel/Sounds and Audio/Sounds and Audio Properties/Audio tab? See the picture below for what this looks like on my machine:

http://www.notation.com/discus/messages/35939/27736.jpg


I know you said that it's a MIDI only problem, but perhaps these parameters affect MIDI playback differently than other audio - I honestly don't know, but I offer it as yet another "something to check" at this point.

I'm stumped by this one, MG. I haven't experienced the problems that you're describing, so I don't have any solutions that have worked for me to offer.

Have you tried checking out the Creative forums? You can go here http://forums.creative.com/creativelabs?region=CLI to the home page, and there are a couple of headings that may be of interest to you.

Good luck with this - you've had an interesting experience so far with the sound card issue. By the end, you'll be the guru of the forum!

Hi Sherry and Mark, Sherry.
 
Hi Sherry and Mark,

Sherry... Yes, been there a hundred times. Deeper into it, I found Audigy 2 listed in the midi tab (with a dozen drivers).

Mark... Yes, I have the Chaos bank loaded. I thought of that, but didn't try unloading (YET) because it should work all right. I'm not sure which bank is included as the default. I may have to wipe and reinstall to find that out.

Hi again,

As a postscript: the only soundfont bank I could find in Win\Sys32\drivers is a 2MB job with Rev++ as part of the name. It looks exactly like the one that was default with the SB Live! retail card that I tried and found with only one synth. I've loaded it and will try actually playing something when I can close all the software I use during the day (it might really be a long scan when I turn the computer on again if I had to use the button with all this loaded).

While I'm hopeful that using Chaos is the cause of the midi problem, the last two crashes occured when the dialog saying I requested information from "go.microsoft.com" popped up with the dial or cancel option. Since I never requested anything that I know of from this URL, I'm trying to find out how to get rid of that now, though I can't see what it might have to do with midi playback using either soundfonts or GM.

Howdy MG,

In answering Mark's question above, you mentioned that you have the Chaos soundfont loaded. Using your Soundfont Manager, how much memory do you have in your system, and how much do you have allocated to loading fonts in your sound card? Also, you may want to try switching between static and dynamic cache - depending on how much memory your system has, and how fast your cpu is, you may need to adjust your settings.

Here's a picture of what it looks like:

Hi Sherry,

Thanks. I hadn't thought of allocating too much memory. I had about 137MB, the same as for the old OEM card. That had only the static cache, but I have set the new one to dynamic. Only thing is, every time I look, it's reverted to static. I thought I could set the number fairly high, and the dynamic cache would take care of the actual allocation. Guess not. I have the number that high because each synth can be assigned its own bank and a couple of large ones would take about 100MB. But I will lower the number a lot for the later-this-afternoon trial.

I found with the old card that if I wanted to replace a bank, I had to have more than double the memory of the currently loaded bank and the one I wanted to replace it with. Odd, and maybe SB has fixed this by the time of Audigy.

Hi all,

Same results, up popped the dialog box and the computer was iced to a one-note buzz. Playing a wave file does not crash the computer when that dialog pops up. Quite apart from the midi problem, I am getting very disgusted with Microsoft for not making it apparent how to turn off that pop up everytime WMP starts up. I've carefully unchecked anything and everything that even hints at the internet, to no avail.

Still looking like a wipe, registry search and delete operation, then a reinstall.

Howdy MG,

This is just a stinker of a problem...

Did you peruse the Creative forum? The Audigy sound card discussion starts at http://forums.creative.com/creativelabs?region=CLI , and it looked like a couple of the topics might be headed in the same direction, though I didn't look closely.

Also, just a note on the registry bit, I use a software program called Registry Mechanic, and I let it do a registry scan and clean up every time I start my machine. It has kept me going quite well. When I first got it, my machine had slowed noticeably, and I had some "issues" with some software running properly. I ran RM the first time, and had something like 800 (yes, eighthundred) errors that needed repairing. Fixed them, and all the problems disappeared, and my machine picked up speed. I highly recommend it. You can get a trial version which does a good bit, but doesn't do deep registry scans. I think it cost $30 last year when I got it.

Hi Sherry,

Yes, I went through both the forums and the knowledge base and found nothing exactly like the problem I was having. That is why I contacted support by email. They answered in just over a business day--a quite detailed answer, I must say. I am to do a clean sweep uninstal in accord with an article in the knowledge base--one which I copied into Metapad, suspecting that I might need it later. I need to shut down Avast Anti Virus, load no services at start up, etc., and do the installation in that state. What is going to happen, since I got the plug and play config. error the first time I installed both this and Nero, I don't know. But once installed, if there are still problems with midi playback (or any other), he wants me to move the card to a different PCI slot to force Windows to juggle the resources. He did seem anxious to hear back from me. I dont' know if that makes me optimistic, or not.

My registry cleaner is called RegSeeker. You can either have it find problem entries and use its broom or can have it search the registry and present you with a list of finds, including whether the entry is obsolete, does not point to a file, etc. This is slow, but you can at least double check on what it proposes to delete. RegSeeker has the virtue of being free, too http://www.notation.com/discus/clipart/happy.gif. So far it has served well, but I haven't used it for some time now http://www.notation.com/discus/clipart/sad.gif.

Hi Sherry,

I'm doing a dry run-through, to make sure that each click produces what they say it will. So far, so good. I'm about to do these:

3. Please make sure you have applied all motherboard and BIOS updates.

4. Please also ensure that you have applied the latest Windows XP
Service Pack updates.

Installed the latest automatic updates today. I think there might be some BIOS updates listed at Dell, but I'm wary of doing those. I did the one that was sent with the Windows XP upgrade package Dell sent, so I might leave it at that.

It sure sounds like I will get EVERYTHING Creative uninstalled, and I may not have before.

There is still a little snow on the ground, but the rain has turned it to patches of ice. It's hard as glass, at least, but still makes the back yard white--the deer that visit my wifes flower beds at night are clearly visible.

Well, it's going to be a long night, but successful I hope. I was going to try doing a setting of a carol, but have lost three days on that.

Enjoy the snowcream http://www.notation.com/discus/clipart/happy.gif Sounds like you have enough snow for gallons...

Good morning all,

Well, the chronicle isn't ended. I did all the wiping and installing and everything worked except midi playing, although it did go on longer before the crash and the inability of Creative things to load from shortcuts.

Maybe due to an error message when the installation was 95%done and it was updating windows drivers: it was unable to locate component--The app failed to start because Plx.core.plx was not found.

So, I re-enabled normal start up, restarted and did the "repair" installation. Now everything loads upon click, so everything works, except you know what, to paraphrase Harry Potter.

Later, after the daily programs are done with, I'll do the "just in case the sweep and install doesn't work" solution, which is to move the care to another PCI slot, so Windows differently allocates resources. If that doesn't work, who knows....

I have an idea (more an intuition) that my video card drivers might be causing a problem. There is an NVIDIA display driver and and NVIDIA win 2000/XP display drivers installed. Perhaps a result of upgrading from ME to XP, so perhaps they should both be there. But I suspect Windows would have generic drivers that would work okay if I uninstall the NVIDIA ones.

But I'll probably just write back to Creative and tell them what happened (and didn't) by following the instructions they sent, and see what they say. It looks like the music writing is pretty much done until they figure it out. (Though Composer crashes like everything else, I did enter a few individual notes without it crashing. Interesting that the first note took forever to appear and sound, but the next few entered normally. I said few because I don't know how many I could enter before the crash, if it happens--and if it does, of course I lose all I've entered.

Meanwhile, I am hoping that using the same PCI slot I took the OEM card out of will work magic...though the fact that it seems to be JUST the midi problem whispers to me that there is a setting somewhere that needs adjusted.

all best,
mgj

A cheery good morning, Mark,
 
A cheery good morning, Mark,

(he said, bravely attempting to wave away the fumes of frustration).

The Geforce MX drivers are still supported. I have 56.16, for 2001. I had to scroll quite a bit to get to that one--I'm at the moment downloading 81.95.

Do you think I should just use add/remove to un-install and disable anti-virus to install the update? Or do the clean sweep of Audigy, also, and install both with all services disabled?

I've also re-enabled the unsupported device, having read that sound can be affected if any device is turned off. Some research revealed that this device--which I've wondered about--is for the Dell support button on the front of the case. I guess I'll follow the instructions for installing the XP driver. It was disabled when I upgraded from ME to XP.

You mentioned updating MIDI drivers. If that's possible, I might as well do that too. But I can't find any reference in Device Manager to MIDI other than in the Audigy properties under midi devices and instruments.

While on the subject of Device Manager, there is an entry, Legacy Audio Drivers, under Sound and Video Game Control. The properties for this one list Total Recorder under Audio Devices, Mixer Devices, and Creative WDM under Line Input Devices. I wonder if this could cause some kind of conflict but have been unable to find any way to make changes, other than check "do not map through this device". I've changed the settings in Total Recorder to use Audigy for all recording and playback, and MIDI playback offers only the same choices Composer does.

There are a few differences that came out of the five hours, or maybe six, I spent at it last night. Midi sometimes plays for a couple of minutes before the crash, and the tone that persists is more like a clarinet playing a bit above it's high G. Also, after about 20 minutes of playing a Wav file, I started to enlarge the media player on screen, and that crashed, too.

Any advice that might occur to you, I would be glad to hear. If I can stay awake, I'll switch PCI slots for the card and install the NVIDIA update (and Audigy, if that seems advisable) late this afternoon.

all best,
mgj

<blockquote><hr size=0><!-quote-!><font size=1>quote:</font>

Or do the clean sweep of Audigy, also, and install both with all services disabled?<!-/quote-!><hr size=0></blockquote>No harm will be done by trying these things (other than perhaps wasting time), and it might help.

It's important to narrow down the circumstances as precisely as possible as to when a problem happens and when it doesn't. For example, can you say with confidence, "This problem happens only when I'm using sound fonts, and never when I'm not using sound fonts"? If so, that is a very important piece of information. I believe you already briefly answered this question as "yes" when I originally asked it.

If the problem really is isolated to sound font usage on your Audigy card, then the problem is to further isolate the problem within the context of using sound fonts with your Audigy sound card. How well one can further isolate a problem depends on one knowledge in the area. Good places to further isolate a problem are ones that are easy to test and seem to have some promise of providing using information depending on the results of the test.

A first test that comes to mind is whether MidiNotate itself might be the culprit. Save your work as a MIDI file. Download a trial version of some other MIDI software. Assign the tracks to the same sound font device and instruments. See if the same problem shows up in that other software. I hope it does, so MidiNotate won't be the blame; but we should know whether this problem is isolated also to MidiNotate and not just any MIDI software.

Another test that comes to mind is to explore where your system doesn't have enough memory to hold the sound fonts. Sherry has already touched on this. There are some different tests you can do. Try loading such one _small_ sound font and playing just it. Does the problem still happen? If not, this suggests that maybe memory is an issue. Use the Windows Task Manager to monitor memory utilitization on your computer. If it's max'ed out while you're playing sound fonts, that's really likely the problem, which you can solve by installing more memory on your PC. A complimentary memory test here is to run other apps that use a lot of memory, to see whether that increases the problem.

You might be unfortunate and find that you cannot further isolate the problem. If you can, though, you'll have a lot better chance of solving the problem.

Hi Mark,

If you mean soundfonts, as opposed to the default soundbank in Audigy, the answer is apparently, no; it happens playing ANY midi file, including those that use only GM instruments.

I don't think Composer is the problem because I've tried playing midi with many other applications. But I will do the more specific test you suggest. I still have the first composition program I ever used, which uses numbers instead of notes (it was meant mostly for creating ring-tones). I'll play one of the little things I did in that.

Perhaps, if installing the updated Geforce drivers and moving the card to a different PCI slot doesn't solve it, memory could be the culprit. I will do some testing later. I just monitered usage with software I have going, and there is not a big drain.

Getting anxious for 4 PM, so I can get at this stuff again.

BTW, I ran Dell's computer check and the only problem found was way to many files in Temp directories. It did tell me, if nothing else of use, that I have the latest BIOS upgrade. That was a flash about a non-flash that I was glad to get!

Hi Mark,

Same old same old. Before opening the computer, I did test midi playback in that old program--no difference in the result from that in any other program.

If it were any, I'd suspect NERO media player. But if it's not open, I don't see how it could be at fault.

Also looked at memory usage for the brief time before the crash--about the same as for wav playback, and below available, though physical memory may have been a bit above, but was during wav play, if so.

The only thing in can think of is to reinstall WMP and Composer, which doesn't seem to make much sense.

Hi Mark, Unfortunately, sin
 
Hi Mark,

Unfortunately, since then I have kept the system information window of Process Explorer open as I used various programs to play files. I never saw physical memory dip below about 41,000. The figures under Physical Memory stay in the same range no matter what is going on. Available about 40,000 to 72,000 and System Cache between about 70,000 and 125,000. Under Paging, Page Fault Delta can swing from around 400 up to 5,000 rapidly sometimes (without a crash). Under CPU and I/O, Context Switch Delta sometimes has big swings, too (without a crash). I had two crashes while watching the Sys Info window, and when the crash happened, the "locked up" figures had no spikes. I spent the better part of an hour watching these figures, and never saw physical memory go below 40,000.

My system is well within the requirements Creative gives, and virtually all of the crashes I've had come with little else in the way of applications active.

Probably, display drivers can be ruled out. After I un-installed Geforce MX, I used Windows to adjust the screen resolution and tried playing a midi file in WMP, and the crash occurred just as quickly as when Geforce was installed.

I had forgot that Magic Score was still installed, since I had made midis of everything and copied them to Songs. But I tried that. It makes but only plays it's .sfd format and only one midi device using whatever soundbank is loaded can be used for all instruments. There was no crash. I did get one in Composer, playing a .not file, so I did further testing, playing a section of my first symphony, fourth movement, since I just started to edit that in Composer, so there is not a lot of difference. I used a section when the orchestra plays the first theme as a kind of hymn and most instruments are playing 3 note chords. First I used the MS Wavetable Synth. No problem in either Magic Score or Composer. Then I used the SB Synth A. Again to problems with the playing. Except, in both there were quite a few pops. (There goes the idea of ignoring midi, simply using .not, and making mp3's.)

I am beginning to think that perhaps the card is physically defective and that depresses me enormously--I'll hear back from Creative on Wed, probably, and there will surely be other things they'll want me to try. Then after who know how many weeks of such back and forth, maybe they will replace the card. Depressing prospect.

Anyhow, with nothing else I can do, I'm going to try the grand sweep and re-install again, with the sound card in the new slot.

I'll do any tests you might think of.

best,
mgj

Hi Mark,

I think I have solved the crime and tracked the criminal to his lair, but the question now is what to do with him.

After doing the sweep and a squeaky clean installation, and after installing the web updates that I downloaded through auto-update, I listened for the better part of an hour to some wav files, and while they played I made changes with the mixer, the volume slider in the tray, as well as opening and applying EAX effects. I almost believed that midi was going to work this time.

Since I had got some crashes playing .not and Magic Score's .sfd files, I decided to test out those first. I had not kept track, but was thinking that MS GS Wavetable Synth did not crash as readily as SB Synth A. So I tried this.

Contorl Panel/Sounds/Audio Midi playbackk default set to SB Sw Synth (which sounds about like MS Wavetable).

Played "Christmas" Symphony 1st movement (all GM in the .sfd and.not files, both) in Magic Score .sfd. It's device set to Sw Synth. Let it play for several minutes. Playback and sound without incident. Stopped playback and changed device to SB Synth A. Crash happened within 10 seconds.

Played "Christmas" Symphony 1st movement in Composer .not, with all staves set to Sw Synth. Everything A OK, until at the same point in the score, I set all staves to SB Synth B. Crash in under 10 seconds.

Physical memory usage in Process Explorer showed 110,000 available while the wave played in WMP.
During the sfd. playback Magic Score showed about 35,000 available and in Composer about 70,000 available. There was no decrease in physical memory available leading up to the crash.
During the wav playing, Thunderbird mail was open and I was connected to the Net. During .sfd and .not playback, the respective programs were the only ones open.

The next stage of the test was as follows.

After the last crash, I set the system default for midi to SB Synth A, which causes crashes in Magic Score and Composer.

Then I did playback exactly as above down to the measure where I changed from Sw to Synth A or B. The results were exactly the same. Even though the system default for midi was Synth A, the crash did not happen until I changed the program from Sw to Synth A or B.

Memory usage was the only difference. Magic score had 117,000 available and Composer started at 27,000 available and climed to 57,000 available at the time I made the change Synth B.

Unless there was a huge spike in memory usage at the crash that didn't register in Process Explorer, I think insufficient memory can be ruled out.

I will test further, using .mid files this time and WMP and Creative's Media Player, but if the results are similar or different, the conclusion that Synth A and B cause crashes on my system playing .not files, while SB Sw Synth does not (at least in the time I let the files play before making the change) is inescapable.

Whether there is a solution in my system settings or not, I don't know. Perhaps Creative needs to do a midi driver update (the version is 5.1, I believe). Perhaps the card itself is physically defective.

If you can think of anything I can add to the tests, I will sure try that.

It's kind of a pyrric victory to have identified and caught the dastardly crook; I have no idea what to do with him.

Hi Mark,

Ha! Jinx ya owe ma a coke, as we said 50 years ago; or was it, great minds think alike.

I think what you wanted was included in the tests I just detailed. The tests before the sweep/install/web up-date in Magic Score were using Sw Synth and MS Wavetable, so it was premature to say that the crash didn't happen with any device, as the lasts tests showed.

Trying to analyze just why MS Wavetable sounds so bad, I had let that play for nearly the whole last movement (the 1st symphony) that time, which has a lot of goodies like claves, wood block, chinese cymbals, etc. That is where I got the idea that maybe MS Wavetable would not crash either an sfd or not file--a theory the tests support.

I appear to have picked up some spyware, so I am going to do my usual Sat afternoon maintenance and a system virus scan. Then, I will further test, though I do not look forward to those long periods of using the on/off switch and file integrity checks.

BTW, I think it is a note velocity problem with MS Wavetable. It's just too **** LOUD, and reducing the note velocity by a factor of up to 50, depending on the instrument, seems to help a lot.

all best,

Hi Mark,

I believe I have got the villain to confess. But first, I decided to continue the .sfd/.not tests, but with MS Wavetable set in Control Panel as the default midi playback device, then set the programs to MS WT, then Sw Synth, then SB Synth A or B.

The .sfd test went as those before, i.e., eveything okay until the switch to SB Synth B. One little difference--after about 10 seconds of freeze, it started again, only to crash almost immediately.

The .not test went the same, to a point. MS WT and Sw Synth played fine, but the crash occured while I was switching to SB Synth A, while "Assign device to all staves" was showing. Nothing was playing.

I think the reason might have been that after the crash, Windows loaded without the file integrity scan, for some reason.

Memory usage was about the same as the earlier tests--36% - 49% physical RAM free.

At this point, I decided to try a RAM cleaner, so got "Clean Ram" from Nonags. Very simple to use--run it and it does a cleaning when physical RAM gets down to 4MB. It made little difference, and in fact the next crash occured while it was cleaning. This was after I had rebooted normally and had swtiched to SB Synth A in Composer and told it to clean now, although there was 110MB free.

Frustrated, I started a process of uninstalling each program that has anything to do with sound. I had done Nero's Media Player, with no difference. I didn't re-install it because I doubt I will ever use it. Then I did Total Recorder, with no change in the results when I played anything using SB Synth A or B.

THE REST OF THE STORY...
I went to Creative forums to try again to find someone with the same problem, but couldn't. While there I downloaded the user manual and read the section of soundfont bank management. The previous software had only a static soundfont cache, which I had set to something over 134MB, since I was using a bank that was 62MB--it wouldn't allow you to change banks unless you had more memory than the combination of the bank you were removing and the one you were replacing it with.

So I opened SBFM and found a dynamic cache of 12MB, with the 4MB default bank loaded. More on a whim than anything else, I upped the memory alloted to 45MB and made the cache static (which reverted to dynamic apparently, after I'd closed SBFM).

With this setup, when I played the same .not I'd been using, I could switch all staves to SB Synth A and play the whole file. With some pops, but not crash. I experimented with raising the soundfont cache and changing it to static again. Each time I raised it, physical memory available went down, but the sound quaility improved.

So, it would seem the eons of nightmare are over, though I haven't yet tried to play a midi file. It would appear that it DID have something to do with memory, only soundfont memory allocated. By extension I suppose more RAM would help a lot, too. I am getting angrier the more I think about it that Creative couldn't have created a pop-up telling one that the soundfont bank cache should be increased/decreased.

Hopefully, I can get rid of the pops in otherwise very good sound by playing with the soundfont cache memory. Hopefuly, too, I can play midi files without crashes now, though as long as I can play .not files and reinstall total recorder to record them, I can get along.

all best,
mgj

Hello M.G.,

It does sound like you have pinned down the problem to memory allocation for the SoundBlaster Font Manager.

Please keep us posted about your testing about how different memory allocation values affect the pop noises and crashes.

Please remind me, how much memory does your system have?

This was a painful experience you went through to pin down this problem with the SoundBlaster Font Manager. Perhaps one consolation here is that we'll write a summary of the soundfont memory problem and solution, so that others can benefit from what you learned.

Cheers
-- Mark
