Some tunes using digidrums has a slight stuttering sound when the digidrums play, i am using SNDplayer 1.51 and have tested on two Atari computers (STE and STFM).
Those i know are ghostbattle, lethal xcess, turrican 2, "oh crikey" by Mad Max and some Jess tunes (just tested a few).
I also tried to play them in JAM but then the digidrums can not be heard at all wich could mean the SNDH files are bad?
WinJAM does play those tunes (not "ooh crikey" though) correctly for some reason?
