I would like to be able to find the chord on the keyboard (and voicing ) myself - play it - hold down al the notes - and then simply press either the sustain pedal to tell SCALER to insert this chord - or maybe a second piano MIDI pedal - set to a different MIDI CC
This - for those who know exactly the chord they want to enter - but require both hands on the keyboard to make out the full voicing - while using another means to enter the (SINGLE) chord - would be great for workflow.
This is a good idea, however it is hard to define what would happen if you DAW plays back MIDI from a track with a sustain message and Scaler starts to change your progression on the fly.
This would need to happen only in some sort of “EDIT” mode. Which would break the workflow a bit.
What you can do at the moment is using the Detect mode and playing the chord you want on your MIDI keyboard.
