One approach might be to amplitude modulate an audio signal with your control voltage signal. That way you could record the modulated carrier with any standard audio recorder. And you could send it to the Capybara as an audio signal (and use the AmplitudeFollower to recover the CV signal).

Analogue Systems' RS300 CV to MIDI converter - (http://www.analoguesystems.co.uk/pdf/RS300.PDF)

Kenton's Control Freak - (http://www.kentonuk.com/keybds_conts_midi-players/controllers_knob-slider.shtml)

SmartController's various possibilities - (http://www.smartcontroller.com.au/instruments.html)

These all convert Control Voltage into MIDI information, which can then be fed directly into the Capybara or recorded using a MIDI sequencer, and then fed to the Capy.

Another possibility would be to simply connect the CV output into an audio interface. I have tried this with a pair of headphones directly into a CV socket, and yes I can hear the signals, which are a series of clicks of different amplitudes. It should therefore be possible to either record or amplify these as audio using an audio interface and then manipulate them in Kyma (or another program, such as the excellent ABox (http://www.andyware.com/abox2/index.html) so as to translate these different amplitudes and also the time between the clicks into MIDI information or maybe even to control and pitch and amplitude of an oscillator.

If the signal you are monitoring is primarily clicks, then you should be able to send them to the Capybara audio inputs. Once they are signals inside the Capybara you could listen them directly, use them as triggers for anything with a Gate or Trigger field, capture them with MemoryWriters to be played back at slower speeds, act as modulators on parameters of other Sounds, use Capytalk to measure the duration between clicks, etc. Once you have it as an audio signal, there would be little reason to convert it to MIDI unless you also wanted Kyma to *output* MIDI to an external synth.

No problem with sending an analog voltage signal < +/- 12 volts to the Capy converters.

There's also a wireless (Bluetooth) version.

A few oyher thoughts - Tim Place makes the Teabox interface that takes CV and modulates them onto a S/PDIF output http://www.electrotap.com/teabox/

Also Angelo Fraietta Makes some good CV-MIDI devices http://www.smartcontroller.com.au/instruments.html
The Micro-CV is wireless

Also http://www.arduino.cc/

There are many other options including the Making Things Board, Teleo, Phidgets, MIDITron, MIDISense.

I have a collection of notes re interfaces on my Blog http://www.activatedspace.com/blog/?cat=5&paged=1

To which I am adding - so if you have other interesting interface options I have missed please let me know.

Hope that helps
