Hello. A feature that I'd like to request is a button on the sample tab, similar to how time stretching and pitch shifting are currently done, that would open a dialog asking for frequency, resonance and mode, and apply the high or low pass filter with these parameters to the sample, overwriting the sample with the result, with an option to undo. I know the MIDI macros feature that switches between high-pass and low-pass modes on the instrument that apply live while the song is playing. What I describe is a sample-focused destructive counterpart (probably simpler to implement as no changes in the format are necessary) to this instrument-focused non-linear editing feature.
