Would it be possible to extend the quantize options so that, as well as ‘hard quantizing’, snapping notes exactly onto the beat, we had a softer quantize option that simply nudged the notes towards the beat.
I’ve seen this in other sequencers (Reason, I think?) – you can specify a quantize percent. Obviously, at 100% it will snap the notes exactly on the beat. At lower settings, it will, for example, move the note 30% towards the beat. This allows you to tidy up a sloppy performance, whilst still preserving a looser, less mechanical feel.
