Control two CC values with one knob?

General discussion

Hi there,

I own a beautiful Electra One MKII and I am in the following situation. I have a midi controllable pedal that allows you to control parameters individually left and right but not stereo. So my question is, is there a way to use one knob to control two different CC values (i.e., mix L + R at once)?

:grin:

Here is an elaborate example

Thanks, I guess I miss something. I could not see how this is related.

Then you need to try out.
You ask to change 2 parameters at once. The morphing control in this example lets you change 8 parameters at once…

Thanks again, indeed, the script is brilliant but the documentation got me really puzzled. So, the morph is global controller for the midi value on the rest of the 7 paramters. However, e.g., setting CC A = 49 and CC B = 50 wont really affect the device. And I know I am in the correct channel since if I create a “standard” fader to control either it works ok (but L or R only).

Is there some other trick I am missing? I.e., except for setting correct midi channel and in CC A = 49 and CC B = 50, should I note something else too?

Again, amazing tool, just need to figure out how to use!

Per control you need to set 3 parameters:

  • what CC number do you want to control?
  • if the morph is turned left: what value should I send ( I guess 0 for your 1st CC and 127 for the 2nd)
  • if the morph is turned right: what value should I send ( I guess 127 for your 1st CC and 0 for the 2nd)
    Also check port and channel is okay and assigned device to the controls you add is the same

short answer is yes, with some LUA programming.

for the master level control, assign it parameter number 49 and make it a standard CC control.
Then, write a simple LUA function and set the name (sendNextCC) in the “function” field of the control (not “format”)

NOTE - the example below assumes you are using the Electra One port 1 and MIDI channel 1. There are ways to make this more generic, but try this first.

function sendNextCC(valueObject,value)
midi.sendControlChange(1, 1, 50, value)
end
