Real Time Control with Envelope

Post by BravePriestess » Tue Apr 14, 2020 1:50 am

I like to do experiments. I'm trying to find a way to control multiples parameters like the frequency of an LFO or cut of a filter in real time. Of course i can do it in an easy way if i create a macro and assign it to a Midi Controller.

The point is that, i would like to control these things while i'm using my theremin. For example as i move my hands near the antennas to modulate the volume or pitch of the sound i would to variate also the bandwith of a BPfilter with the same envelope that i'm creating with the movement of my hand.

I know that probably this could sound weird...but i'm grateful to anyone that can help me with my weird ideas.

Thank you.

Hi BravePriestess,

the easiest way to do this is to use a theremin which puts out control voltages from pitch and volume circuits as well as shaping the theremin's audio signal itself. These CVs can then be used to control anything on a synthesizer which has a CV input (filter cutoff etc). Suitable theremins are, for example, Moog Etherwave Plus, Etherwave Pro, and also Etherwave standard if you build the hotrodding circuits yourself. I can assure you that this works - I use a hottrodded EW and an EW Pro with various CV-controllable synthesizers.

Otherwise, if you're using some other theremin without CV outputs, you could use separate modules (quite a few around) which do envelope following and pitch tracking, converting signal level and pitch to a CV.

Best regards,

Jim F.

The Moog Theremini is not only a very fine Theremin, it also excels at being able to transmit both user-scalable CVs AND Midi CCs (simultaneously, if desired) from the antennas.
It is also highly configurable on-the-fly via Midi, making it a great controller for experimental and highly customized setups.
Most of these capabilities are under-the-hood features, but the tools are certainly there for those who make the effort to learn and utilize them.

that is good info, thx!!

someday I would love to get a Theremin

ps shouldn't this be in the Theremin thread? might be easier for ppl to find
