MIDI - Can I map two controls to one MIDI knob?

Having trouble with LMMS? Ask about it here.

I'm trying to make sci-fi droid noises, using a technique I saw in this YouTube video:

At about 4:30, he links two controls to the same MIDI knob, so both vary together. Right now I'm trying to do this but can't get it to work.

Here's the tech part...I have an Adafruit Macropad, using this code:

This defaults to the knob set up to connect to Pitch Bend. This works fine. But I'd also like to connect the knob to the Coarse setting.

Can LMMS connect two controls to one MIDI knob? I try to assign it but it gets ignored. If necessary I can put a different setup together with regular Arduino and a potentiometer.

I found a project that works:

This allows you to connect a few pot knobs to an Arduino, install a couple of free drivers, and then install software on the Arduino.

Once you have this set up, you CAN link two controls to one pot on the Arduino.

Right-click a control in LMMS, pick "Connect to controller" and then wiggle the knob you want connected. The Connection Settings dialog will identify the channel and connection. Click OK, you're done. Do it again and wiggle the same knob, then both controls will be linked to the same knob.

Cheap and quick!

You solved it yourself! Good and nice to post the solution here for everybody's benefit!

Thanks! I always try to leave a solution behind. Someone will come along in a few months and will need it.
