One of the Batman games had almost nothing but slap bass samples on the WAV channel.

You can get a nice octave if you do single cycle waves

It's a pain in the butt, but it works, I've done it. I suggest naming all the samples after note values, and putting only one octave in each sample pack.

Oh I didn't know that! I'll look up how to do that

You could easily do this with LSDJ, just create a sample pack with each of the notes you need.

Does anyone know of any trackers for the DMG featuring melodic sample support? I know there are a few games for the NES with sampled basslines that sound pretty nice (absolutely filthy, but nice) and I'd love to get that kind of sound .
