Perhaps on stock filter modules the tacking feature should be centred on middle C instead of increasing the cutoff for all notes.
Right now turning the tracking from 0-1 bumps the cutoff up five octaves when playing middle C. I've always found this counterintuitive as you always have to scale back the cutoff frequency when adding tracking. But you could instead have it so that, on middle C, the tracking knob had no effect and on lower notes it drops the cutoff while on higher notes in increases the cutoff accordingly.
