In Pyramid’s Scale effect, it should be possible to transpose by more than +/-12 semitones. I think this has been implemented on Hermod already. While this does not really make sense on MIDI synths, it is very convenient on modular synths where retuning oscillators is not fun at all.
Currently, the Chance effect plays or does not play a note based on a certain probability. Instead of playing / not playing, it would be interesting to have a skip / play feature in the sense that “with a certain probability, a note is skipped or played”. This would affect the length of the pattern, of course. Since polymetry/polyrhythm is a strength of Pyramid, a probability-based skip effect would be a very powerful addition.
