"Incremental Button" function from NRPN with 0/1 values (toggle)

[vonglan]

On the OB6, there are many toggle buttons, for example "Filter Envelope Velocity Sensitivity".
They send NRPN values 0 and 1 alternatingly (toggle). This can not be changed on the instrument (and I suppose it is the same with most other hardware synthesizers, only they use CCs instead of NRPNs).
I would like to use these buttons as "incremental buttons" (like I do in my "hard coded" JSFX mapper that I want to replace with ReaLearn).
One obstacle is #268 , which might be a bug.
Another is that the button presses that send NRPN 0 are ignored by ReaLearn. I understand that this is intended. But for this case it is not helpful. Can this be overcome, or is there a workaround for this?

Ah, such a pity. But I guess one can already be lucky that this kind of synthesizers can be used as controllers at all.

The problem can't be overcome at the moment. I think the way I'm going to implement this is to:

1. Introduce the "Source character" dropdown also to NRPN sources (not just CC).
2. Introduce a new source character "Toggle button (avoid if possible!)" which will emit value 1, no matter what.

Ah, such a pity. But I guess one can already be lucky that this kind of synthesizers can be used as controllers at all.

On the other hand, hardware synthesizers offer very useful labels beside their knobs ("Frequency", "Noise", ...), so that is an advantage when using them as a VST controller :-)

Thanks for implementing this!

Should this already be in pre9? I see that the commit references pre9, but I do not finde it in the GUI.

[helgoboss]

Yes, it's in pre9 Source Type "(N)RPN value", Character "Toggle-only button".

[vonglan]

I don't see it. Am I blind?

[helgoboss]

Character is only available for 7-bit NRPN (same as with CC).

[vonglan]

Ah, now I see it.
Unfortunately, the OB6 always sends 14-bit.
ReaLearn does currently not "see" the 14-bit messages when source is configured as 7-bit. Could that be adapted? The OB6 sends only 0 for the higher 7 bits for these buttons anyway.

[helgoboss]

What a strange usage of NRPN, using a 14-bit message for a button press. But okay, then I will enable it for 14-bit, too. But the encoder types don't make sense there :/
