Using MIDI expression pedal to control wah wah in Guitar Rig 6

academyofrock

I have an M Audio MIDI Expression pedal which works with pianos as a volume control. Can it control the wah wah pedal in Guitar Rig 6? I have searched but found nothing on how to connect and use it.

If it's the EX-P pedal it needs to be connected to an interface/keyboard that converts the pedal output to MIDI. Once you've done that you should be able to map the MIDI from the interface to GR6.

Yes, I should have mentioned that I have an S88 keyboard which the EXP pedal is connected to. It sends MIDI and piano sounds can be controlled by it,

You can validate the behaviour via this magnificent tool:

It should show what MIDI info is used so you can map it to GR.

I will try this thank you

The Expression Pedal registers off and on when I depress it on the MIDI monitor.

If I right click MIDI learn on the wah in GR6 and move the wah knob no response from MIDI monitor.

If I right click MIDI learn on the wah in GR6 and depress the Expression Pedal, nothing happens from MIDI monitor.

So EXP pedal works but is not modulating the wah pedal.

Does that make sense?

hello @academyofrock ,

It appears from the logs that the MIDI events are coming in from your Komplete Kontrol expression pedal. MIDI learn on the other hand will not work when your turn a know in GR6, MIDI is uni-directional from your keyboard towards GR, not the other way around. I think the next steps is to go to the preferences of Guitar Rig and enable your Komplete Kontrol keyboard as a MIDI source. Afterwards go back to MIDI learn of the wah-effect and press the expression pedal, this should normally work.

Grtz,

Wouter

Thank you for this, I started the standalone GR 6 app and the boxes for MIDI control were all unchecked. I have now ticked them. I restarted Logic and a version of GR 6 but can get no control of wah pedal. Should I restart the mac?

I would first try to get things working in the stand-alone version of GR, Logic is a different ballgame in regards to MIDI-routing. In a recent version of Logic Apple changed the behaviour of MIDI-controllers without interacting with or informing 3rd parties, since then I can’t use my MIDI controller anymore and decided to switch to Ableton Live.

Thank you Walter - I will try that as you suggest. My best, Peter

OK, I have got the wah pedal working on the stand alone version of GR6 by assigning channel 11 to the wah pedal (see screenshot). When I go to the GR6 in logic, I can assign CH 11 to the wah for control from my mouse, but the MIDI pedal does not control the wah. I can see that the pedal is working via MIDI monitor by no

wah control.

Great to hear the stand-alone setup is operational 👍, communication is working. I’m no longer using Logic, hopefully someone else on the forum can support you on that topic.

TYSM for your help Wouter. I have made good progress thanks to you.
