Rack: MIDI learn

[Be-ing]

It would be awesome if modules' knobs could be mapped to MIDI controllers.

Andrew Belt say "MIDI learn might land in v1.0 in November/December." :-)

A MIDI CC in with 32 output jacks for all the 14 bit controllers looks most
general. Has any one ever had a controller which needed learn which was not
one of those? Maybe it would need a flashing light so that the control
could be seen.

I'll make a MIDICC2CV module with 16 changable CC outputs in Core later, which is closer to what you're talking about. But this issue's request is about MIDI-to-knob mapping in Rack itself.

[Euphorbium]

@AndrewBelt Are you working on this? I might try to implement it, need this asap. Already mapped 2 of knobs by modifying current midi module (my novation launch key mini has no pitch or mod wheels)
Ideas on the looks of the module?

[AndrewBelt]

It might be ~3 weeks before I can get around to the MIDI Interface revamp, and MIDI learn will likely be even after v1.0 releases. It's still on the TODO list though.

If you need it urgently because of a live show or something, you can hack MidiInterface.cpp near the lines

    case 0xb: // cc
        switch (data1) {
            case 0x01: // mod

by changing the data1 hex number to whatever your controller emits. Then, the Mod output will respond to that controller knob.
EDIT: Sounds like this is what you've already tried.

[Euphorbium]

Yeah, already figured it out :)

Sorry for the other duplicate request post. +1 on OP here. Would LOVE to see Midi Learn added at some point if coding time etc allow.

[wilmermurillo]

Can't wait to this feature! I would defenitely abandon Reaktor for VCVRack when Midi learning is supported. Thanks for all of your effort!

[JoakimLindbom]

What would be the proper way to implement this? Is there a preferred way to send messages from one module to another (except via Wire::step())?
One way could be to implement a MIDI-wire, working as the normal Wire, but sending 4 values. Another would be to extend ModuleWidget::addParam and implement a ::Step()-method on Knob where received values override the Knob value. I guess the leter is better.

[AndrewBelt]

The way I'll do it is have a special MIDI-learn core module and a special GUI for hooking up knobs to MIDI channels.

No MIDI wires.

[wilmermurillo]

@AndrewBelt That's exactly how I had imagined it. Thanks for putting this on board! We love you and VCVRack :D

[sixstringeek]

Need this to control filters, functions with midi fighter twister if I figure out a template I’ll share it!

[Dopplgngr]

Would be great to have an "Instant Mapping" mode for MIDI Learn - to address the problem of 1 physical controller meeting a high number of virtual controls and dynamic modules placements. E.g. always map all knobs of active module. Use case would be right hand mouse-navigation to activate modules, left hand could stay on controller moving knobs of that active module.

[amp3rsand]

any progress on this feature?

[AndrewBelt]

@amp3rsand Won't start until Rack 1.0 development is active, which will be 4-6 months from now.

[bgracie]

Thanks for your great work on Rack @AndrewBelt! When it's time for this feature, might be cool to consider bidirectional mapping -- so ppl with controllers that programmatically show current position (lighted encoders, touchscreen apps) can get proper feedback if they turn mapped knobs from within Rack. This would also open up the possibility of using another program with a more timeline-based UI paradigm to snapshot and sequence parameter changes.

[alectron]

+1 for a Midi-learn feature, that would be brilliant.
Thanks for all the work & love put into this beautiful project!

[alectron]

Is this still on track for the 1.0 release ?
I'm still hoping to one day be able to have a dedicated surface mapping... eg use a Novation Launchpad to control the VCV consoles controls among other things.

[KoreTeknology]

It was in my suggestions list, i would really support this feature.. how can we help this one to come up ?

[amp3rsand]

Not sure how we can get them to implement thus feature but it sure would
make it much more tactile.

+1 for this feature. Its the one big thing I'm missing!

[0mars]

It's working on rack v1-gpl (branch) for those who can't wait, I absolutely love this feature!

[nay-seven]

@0mars If you have a Mac release to share, i'm interested ;-)

[0mars]

@nay-seven unfortunately, I don't have a mac.

[nay-seven]

ok, no problem, thanks anyway ;-)

[gilbertohasnofb]

Has this feature been implemented in the recently released version 1.0?

[AndrewBelt]

Yes, I believe this can be closed
