Oh yeah - the tracker itself wasn't the sampler, but one would often import sampled waveforms (or borrrrrow 'em from other tracks). I seem to remember fasttracker ][ (which i spent a ridiculous amount of time with as a teenager) had some 'draw a waveform' functionality which is possibly the worst sound interface imaginable.

Hahaha I hadn’t used fasttracker ][.

Sounds like you had a lot of fun in it though?
