I would like to hear how people may be converting incoming audio into Control Voltage for eurorack use.
This year i indulged in building a eurorack synthesizer and i would like to start using some interesting libraries i have found in pure data to control my synthesizer but i want to do it elegantly.
For example: I am trying to make a Fractal CV generator with pure data. I am using Ben Bogarts "Chaos" libraries and i am hoping for some ideas on how to convert the streams of data into usable CV outside the box,

Hey Ricky,
I've done some major google searches and have yet to find where one can get this Audio cape [bela?]. Can you point me to it?
Thanks, Alex

I'm right now controlling an analog synth via Pd :-). I'm just using an arduino - works well. It depends how many CV sources you wanna have, though. Generating trigger signals (e.g. for envelope generators) is really easy because you can directly use the digital outs. CV for modulation is a bit more tricky because you have to smooth the PWM outputs of the arduino with low pass filters. I found that using two RC circuits in series (with C = 1 microFarad and R = 3,3 kOhm) works decently for pins 5 and 6 on the Arduino Uno (pins 9, 10, 11 have a lower PWM frequency and therefore might need a lower cutoff frequency). I'm thinking about trying out some multichannel DACs with 10 or 12 bit because PWM on the arduino is only 8 bit. DACs also operate at a much higher frequency so smoothing would be much easier.

The TLC5940 or TLC5941 PWM ICs have 16 channels of 12-bit resolution, and can be daisychained for more channels. They are supported by a library for Arduino. Although they are usually used for LEDs they also work for servos or general PWM.

Ahh cool, yeah, I saw that page but only quickly scanned and found no
info where to get the hardware, the place it links to has this at the top of the page:
"Update 25 November 2014: software link below; stay tuned for hardware
info"
ha.. I just emailed Andrew directly. Thanks!

I would like to hear how people may be converting incoming audio into
Control Voltage for eurorack use.
This year i indulged in building a eurorack synthesizer and i would
like to start using some interesting libraries i have found in pure data to control my synthesizer but i want to do it elegantly.
For example: I am trying to make a Fractal CV generator with pure
data. I am using Ben Bogarts "Chaos" libraries and i am hoping for some ideas on how to convert the streams of data into usable CV outside the box,

wow, this looks great! I'm certainly gonna try one of these for my next arduino shield. thanks!

The TLC5940 or TLC5941 PWM ICs have 16 channels of 12-bit resolution, and can be daisychained for more channels. They are supported by a library for Arduino. Although they are usually used for LEDs they also work for servos or general PWM.

are you aware that you can increase the pwm frequency considerably? still less for 9 10 11 but far higher then by default for all pwm pins.

I'm right now controlling an analog synth via Pd :-). I'm just using an arduino - works well. It depends how many CV sources you wanna have, though. Generating trigger signals (e.g. for envelope generators) is really easy because you can directly use the digital outs. CV for modulation is a bit more tricky because you have to smooth the PWM outputs of the arduino with low pass filters. I found that using two RC circuits in series (with C = 1 microFarad and R = 3,3 kOhm) works decently for pins 5 and 6 on the Arduino Uno (pins 9, 10, 11 have a lower PWM frequency and therefore might need a lower cutoff frequency). I'm thinking about trying out some multichannel DACs with 10 or 12 bit because PWM on the arduino is only 8 bit. DACs also operate at a much higher frequency so smoothing would be much easier.
