Midi gid or piano roll for performances

I know it’s been mentioned, but it would be nice to see the performances on piano roll or grid so we can edit them. Even chords would be nice to see and edit this way.

We can even make our own custom ones. (user preformances)

This can have 2 levels. One would be modular, each performance (phrase, sequence, bass line, etc…) could have a ‘block’ pop up where you can see and edit the notes. And chords too!

Then, you can construct each ‘block’ on a grid. This grid could either be just blocks, or you can see inside the block so that the whole progression can be seen.
