I think a Midi Sync option for the Portamento Duration Slider would be a nice feature.
I'm programming a sound for a Rush song, and the Portamento Slider is difficult to work with.
If it were synced with midi, I think this would solve a lot of issues.
In the image below, I photoshopped a mock "Midi Sync" button near what I'm talking about.
When it is active, the Portamento slider range would then step through different note multiples/fractions of the beat.
I'm thinking for a 1/4 note, the Portamento duration would be a quarter of the BPM.
Also, Portamento movement rate seems fixed. Can it be a function of the distance to the next note divided by the Portamento time duration?
When would someone want a fixed movement rate?
Is there a way to mimic this proposed feature using some of the other controls?
Maybe I'll try Garagebands smart controls and Pitch Bend?
