Invalid Midi file header: missing MThd chunk id

[newbee]

Oh dear, I am SO sorry to hear that. I had just found a Post by him regarding this Error, back from 2002, which I will try to insert below.

I will also try to send you a couple of the files (out of a great many) that have the problem.

Forgive me... but maybe this will help in the meantime? It's a shortened Quote from that Forum regarding the Error I get.

MidiNotate chokes with an error message -- "file was downloaded, but it is not a correctly formatted MIDI file...cannot convert to notation. Invalid MIDI file header: missing MThd chunk id"

Some, perhaps all, of the MIDI files at the Classical Midi Connection web site (www.classicalmidiconnection.com) are not correctly formatted MIDI files. MidiNotate cannot read these files.We successfully reviewed many of them when we listed them at our www.notation.com/midifiles.htm page. I may have to drop the Classical Midi Connection from our list of recommended MIDI file sites.

Someone named Les Winters. I sent him a message about this. No reply yet. I have a feeling it's something intentional, to prevent unauthorized proliferation of the files.

Posted on Sunday, May 05, 2002 - 11:13 pm: Hi, Steve. Given the contact you found, I have also sent Les Winters at the Classical Midi Connection a message. Not many weeks ago my wife and I successfully tried out MIDI files from this web site. So, this is a recent problem. I doubt that this web site is intentionally reformatting the MIDI files so that they cannot be read by programs like MidiNotate, There's some other explanation. If I don't hear back from Les Winters in a few days, I'll dig into the MIDI file data to see where it deviates from the expected MIDI file format.
