Firstly, the synth machine is disabled for the pad that the Bass sample is on.
I’m using a C note I sampled from Bass guitar, so it’s pitch perfect. When I play it in chromatic mode, each pad changes pitch each time I hit it, even the one that is supposed to be the original sample.
If I hadn’t spent so much time sampling Bass tones I’d just let it go. I actually sampled every note on the neck, and chords, arpeggios, picked and plucked notes, and with effects.
