In Piano Roll select random or only odd/even notes for moving them around form a group of notes or a measure.
No random select. Either select each event by clicking, or use the marquee drag selection.
Being able to save quantize patterns (swing, shuffle, etc)
You can create your own library of patterns by saving individual note patterns to a MIDI file, which you then can drag onto tracks. You cannot apply them as a groove template.
Create an automation lane with a sine wave, saw, triangle, etc shaped automation curve for tempo based constant variatons in the chosen parameter
You’ll have to draw a single single sine oscillation, and then repeat the curve sequence event on the track.
