@3ndymion: thanks. I actually can make arps easily in the Game Boy version by just pressing start on the note (splits the note into 4 notes that will be repeated within one envelope) ... I was asking about shuffle, that's what I used the delays for. Sorry if I was unclear. Glad you like my music
@ryba: Thank you. Yeah I'm actually making pretty moody non-chip-music, too. I've always wanted to make real chip music though and I'm enjoying the limitations. Eventually I'll probably make hybrid music, mixing tracks I made on the Game Boy with other synths. That's one reason I asked about what you guys think is the border between chip music and non-chip music.
@basspuddle: I'll be modding my Game Boy in a bit with a backlight and prosound. I'll perform some more tests if it's the Game Boy's clock that's drifting or if I just messed up loading patterns with different BPMs. If its clock is drifting I'll definitely consider also looking into replacing the crystal or what it takes to get a more stable clock. Maybe a MIDI clock via link cable?
