I’m really hooked on Phrases. But I’d like to suggest some ideas that might help with the workflow.
Groups - When you create a Phrase. I’d like to see that Phrase as a group. That way, you can add/connect how many instruments as you want to that group. They will all play the original Phrase with the selected sound. This instead of having to duplicate a Phrase for a new instrument.
Ghost Visualisation - Have an non editable “ghost” representation/visualisation of the Phrase in the pattern editor and also in the Pattern Sequence Matrix (like normal tracks are visualised).
