I am not sure why but yeah I think something happens this for sure happens on the level Rock It in Crash 2. Also it seems when I do constitute the vab files that some levels and even the warp room in Crash 2 seems to be missign at least 1 or more instrument when I convert the vab to a sf2 (sountfont that is used with midi) and yes export midi should also somehow generate at least the vab file and use some sort of command line tool with crashedit in backgound to convert it to sf2 and delete the vab or save the vab and use https://github.com/vgmtrans/vgmtrans to convert it to sf2.
