Converting audio input to MIDI or pitch/CV-out information

Electrosmith Products Daisy Patch

Hello Daisy Forum!

I am in my first, blissful week of Daisy Patch-dom. I already have the unit running in a quadraphonic setup at home; much fun!

I am interested in translating audio input (i.e., coming in through AUDIO IN 1, IN 2, IN 3 or IN 4) into either

  1. MIDI information
    OR
  2. Pitch-CV (or other CV) information (i.e., output via CV Out 1 or OUT 2).

Is anyone aware of a program that does this? I am operating in the gen~ environment, so am particularly interested in a gen~ patch, though I am happy to consider alternatives (e.g., C++) as necessary.

Thanks for any help or advice!

Brief context: I run an experimental / avant-garde music venue in NYC

I intend to use this unit in quardraphonic performances at the venue, for music composed / performed by others, as well as myself.

There was some discussion about pitch detection here

Regarding quadraphonic audio, FAUST has some relevant functions that I’ve ran on Daisy Patch with OWL successfully. Things like panner, mixer and a suitable reverb (4 channels from an FDN reverb). They tend to be a bit more computationally expensive than I’ve expected out of the box, so using C++ might be required if you want to have more than 2 running at once.

Thank you for this information.

I am considering doing some coding in C++; trying to determine how beneficial (or simply necessary) than is likely to be for the more-ambitious projects.

I appreciate that there is a potential for putting an inordinate computational load on the Daisy chip. A viable alternative is to use a specialized pedal earlier in the signal chain to produce a parsable signal.
For $449, there is the option of an impressive, quadraphonic synth pedal, the The *Poly Effects Beebo Multi-Effects Pedal:

Quote:
The MIDI to V/oct module allows you to drive the synthesis modules from MIDI note input.

For a more-focused pedal, but still $229 (~50% of the price of the profoundly-impressive, quadraphonic Beebo), there is the Ghost Writer by Recovery Effects:
GHOST WRITER PEDAL (Audio to MIDI device) – Recovery Effects and Devices, which will emit MIDI signals (that in turn can be parsed by a significant portion of existing modular-synth setups, including those involving the Daisy.

I will probably end up going with one of these, leavingthe computaitn headroom in the Daisy Patch for other tasks, such quadraphonic mixing.

I’m wondering - what kind of input do you want to handle? Is it expected to be musical notes, that could be expressed in terms of NOTE_ON, NOTE_OFF?

That Poly looks like an interesting device, but I have trouble gleaning much information from their website or manual.
