There are notes missing on CMF playback. I think it could be to do with the number of instruments (and so could potentially be an easy fix, I hope). @Malvineous, what do you think?

Attached is an example of a file from the game Xargon. Included are the CMF file and two different recordings of it (one through ADPlug and one converted with a CMF Tool several years back). You'll notice that the bass notes are consistent throughout the CMF Tool's output, whereas ADPlug skips over some of them (leaving spaces).

Here's an example: example.zip
