Theremini MIDI to Axocontrol

#1

Hello,

Is there anybody who can help me with following matter?

I want to control 2 of the knobs (e.g. volume and vibrato or reso, or other(s)) with the sensors (Volume and Pitch) on the left and right hand side of my Moog Theremini to control the by hand movements cq hand gestures.

According to Moog it is possible via CC2 (Volume) and CC20 (Pitch) to connect it to USB from Axocontrol.

I am using the patch Little Classic of (Thank you!) TIAR.

I do not know where i can do it. Does anybody know?

The Theremini is recognized by Axoloti:

I know it is not possible to send note MIDI's to axocontrol, but maybe it is possible to use the Windows Axoloti software and use the keyboard within the program!

I tried to find a way, but me as a newbie I don't know where to start and to look a way to find the parameters and the way to match it with the CC Midi codes of the Theremini.

I sthere anyone who can and is willing to help me?

Greetings Peter

According to the Theremini manual, you can set up any CC to be sent by it. To control any dial in your patch via MIDI CC, just right click it and choose the correct number under "MIDI CC". If you want to control something that has no dial, but an inlet, use a "midi/in/cc" object.

Thanks borututuforte,

I found that to send midi message from my left antenna of my Theremini I can send CC2 (Volume)

I would like to send it to #1 Pot (PA5) of my Axocentrol dedicated for CutOffDist.

Do i have to rightclick on the box "gpio/in analog" and go to "edit object definition" and then to:

tab "Inlet" or tab "MIDI" I cannot inser any midi CC here?

I am afraid i do not exactly know where i should do the alteration?

Maybe you can show me the exact path, pls.

Thanks Peter

As I said you can change the transmitted CC number on your Theremini if desired, check the manual.

You can not send a MIDI CC "to a pot", just to parameters. A "gpio/in analog" object reads from an analog input and puts out a value to control things like filter cutoff. So pots as well as MIDI CCs are modulation sources, not destinations.

You probably want to leave the pot connected and use your MIDI CC for additional control of filter cutoff? Then you'll have to add the value of the MIDI CC to the value of the pot using a "math/+" object:

EDIT: I forgot to connect to the "Cutoff" inlet. As the input for filter cutoff is processed differently, add another "math/+" object to add MIDI CC and the processed pot value (coming from "math/<<").

Thank you for the explanation, I understand I think!

I'll give it another try.

Bye Peter
