Issue: Midi CC learning of mixer chains panning not reacting to external potentiometers consistently #1178

Closed Aethercircle closed 1 month ago

Aethercircle commented 2 months ago

Describe the issue

Oram does not respond consistently to some potentiometers on an external controller synth, that have been assigned to the panning control of mixer chains. After Midi-learning on each chain, linked to different external encoders, some incoming CC messages happen to control the panning of two chains at once.

Steps to reproduce the behaviour:

  1. Create a snapshot of at least six chains, with whatever synths/processors engaged.
  2. Individually Midi-learn the panning control of each chain (crtl + .), through six encoders/pots on an external Midi control surface/keyboard/synth.

  3. At the end of the Midi-learning process, try and set the panning of the chains with the six related encoders/pots.

    Expected behaviour

    Each encoder should independently set the panning position of just its connected chain.

Actual behaviour

Some encoders affect two proximal or distant chains at once.

Please provide a snapshot that demonstrates this issue.

I have tested and not reproduced the issue. There has been a change to the code that fixed stale MIDI CC binding not being removed so maybe this was the cause.
