New External Instrument track concept - recording both MIDI and Audio to one track w/ smart sync

When recording keyboard/synth, I like to record both MIDI and Audio.

Why not combine this into one track type? Quantize MIDI to the audio to correct MIDI jitter/latency.

You could edit the MIDI and have the audio reflect, and vice versa. And or, you could edit the MIDI, have the audio reflect as a preview, and then re-record only the audio using the new edited MIDI.

The relationships are maintained and sync’d so that one always knows which audio and MIDI are related.
