MIDI (or OSC!) to CV?


#1

I notice that Memory Palace has MIDI in. This got me thinking about the possibility of integrating some sort of MIDI CC to CV module into a system to expand modulation possibilities. Or, better yet, OSC to MIDI since that would allow for much greater resolution (though I am surprised that I can’t actually seem to find an audio-focused module that does this at all; maybe I am just getting tripped up because searching for “OSC” brings up a load of oscillators?). Better still: wireless OSC.

Anyone use MIDI at all in their systems? Or OSC, if possible?

AS a VDMX Ninja i have had the Exact same unge: to integrate control for the moduler video synth from my Control setup, using the step sequencers and waveclock audio sync etc…
But have found no osc modules(almost impossible to google OSC in the moduler World AS it gives Me all oscillators, so perhaps there is something out there…

I have had some succes With the befaco MIDI Thing module. It Can be set up to output 4 CV channels, and have midi in on the old DIN connctor.
But it is quite a hazzle: from computer to midi usb interface, to midi thing, to skaler, on to the actualmcv input, and Then it only gives about 60 steps of resolution because of the onde octave Per volt principle for the midi thing. But i have 4 CV outs, which is something.

I have begun developing a usb midi to CV module with a friend. He just pinged me he have an early breadboard prototype giving 0-1v cv from pitch Bend, which is 12 bit, meaning 4096 steps of resolution, and no scaling Nessecary.

A Lot of channels out should be possible in this architecture, but dont yet know If this Will be a private project, or made info a published module yet.

Making the osc version is beyond my friends knowledge.

Theres a couple of modules able to do that.
OSC: https://www.rebeltech.org/product/open-sound-module/
https://github.com/hdavid/ports
or even: https://github.com/mxmxmx/terminal_tedium
For MIDI there’s of course many options, CVPal being the cheapest, easiest to build https://www.thonk.co.uk/shop/cvpal-kit/
I’m developing a small 1u utility as a ‘midi host’ to Orion Midi converter, meaning connecting a Midi controller and changing parameters internally in the Orion series modules that accept that.
btw, @creatorlars , theres two Midi TRS standards (A and B) widely used, which one is the one present in Memory Palace. this one i guess: https://www.midi.org/articles-old/trs-specification-adopted-and-released.
To adapt that 1u module as a USB-midi device would be pretty easy.

great idea more 1u modules for the video folk
