Get/Set value in `MIDI CC/OSC only` actions

[Navelpluisje]

In the REAPER action list are action which are `MIDI
CC/OSC only` like actionId 999. Is there a way to retreive and set the value in these actions?

[mschnell]

The Midi CC value is set by the incoming Midi message (on the Reaper Control Path i.e. fed by a Midi device with "Control" checked and by plugins like "MidiToReaConntrolPath" or "ReaLearn" or by directly using the "Send Midi" Reaper API in a script).

I found that the Midi value can be retrieved by an appropriate API call " get_action_context(#filename,sectionID,cmdID,mode, resolution,val); ", but OSC values can't be retrieve. Hence setting the value does not make sense.

I hope for improvement on that behalf, but I did not find anything yet.

OTOH ReaPack:ReaLearn seems to be able to receive and decode OSC messages properly.

Set value: Yes, but only as "normalized" 7-bit or 14-bit MIDI value, see KBD_OnMainActionEx. E.g. you can't pass dB for metronome volume.

Get value: I wish there would, but I'm pretty sure there's no such way ATM. An action in REAPER just doesn't have the concept of "a current value". The exception are toggle actions, which can report their on/off state. But there's no such thing for reporting e.g. a floating point value.

ReaLearn maintains current values for action targets to have at least some pseudo feedback, but of course it falls short in some ways.

Thanx for the replies. Will try them

Not a general answer, but for getting current metronome volume (action 999):

Should also be possible (normalized) with get_action_context() as mschnell wrote, no?

edit:
Ok, that's for scripts only it seems, maybe of no use for ReaLearn(?).

Yes, only accessible to the script being invoked. Even more important: The value doesn't represent the value of the thing being controlled but the incoming value (the MIDI CC) ... so not usable.

Thanx, this is working as I expected and hoped.
