Howdy John,
Glad to know we're on the same wavelength here
Thanks for the added info. There are a couple of things we can check out now that we know Composer isn't seeing anything at all from your MIDI device.
On some devices, there is a switch, either physical or electronic (setting), for "MIDI mode". I'm not sure about your Kurzweil unit, but please do check in your user's manual to see if there is such a switch or setting. Some units have something like "Audio only", "MIDI on", "MIDI through" etc. If your unit has such a switch or setting (many users have had to make such settings because for some reason the default is "off"), try changing it.
If all seems to be as it should be and you're still not getting any recognition by Composer, then please try out a small program (not developed by us) called RedDot Forever, available free at
http://sourceforge.net/projects/reddot/ This program's sole purpose in life is to record .mid files. If it detects and records from your Kurzweil, then we'll delve deeper into why Composer is not detecting it. If RedDot doesn't pickup your MIDI device, then we'll have to look more to the Kurzweil and/or the CME cable interface.
ttfn,
Sherry
