Doepfer

Hi all,

I have just recently bought a set of Doepfer modules to start playing with sounds, I'm not a great keyboard player (mostly left handed!!) so I thought I might experiment with guitar input. I have the external input module A-119 which will provide Envelope Control and gate put next I would need pitch tracking...

I see on the Doepfer website there is a possible future Pitch to CV (A-195-1?) but no release date. Any further thoughts on this module?

Has anyone tried any other means of tracking external pitch? Success?

Thanks for anyone's time on this, I'm looking forward to years of fun making various sounds :-)

I've always thought a Pitch To CV module would be perfect. So I add to your query,

The only Eurorack module I know until now is the Analog Solutions RS-35, 
which is out of production unfortunately.

I assume Dieter will tell something about the state of the A-195-1.

The module is still in the "holding pattern". The problem is to derive a clean rectangle signal from the input signal under (nearly)
all conditions. Measuring the frequency of the rectangle and generating the CV is then simple. But especially during the attack
phase and for signals without (or low level) fundamental it's difficult if not even impossible without a DSP. For steady signals
with a strong fundamental it's easy to derive the CV. Maybe we will release it some day "as it is" and mention the drawbacks.

Thanks for the replies.

Dieter, I'm sure people would accept the issues, you explain them very well. I'm a programmer and hardware designer myself so I can quite understand the difficulties of extracting pitch from a complex waveform :-)

I look forward to any possible release you might do in the future...

Hello Dieter,

you may have a look at the old Korg X-911 guitar synth. It provides a 
quite reliable tracking. I can send you the schematics and may borrough 
you my X-911 too. The created CV is V/Hz, but a conversion to V/Oct 
should be doable.

I was about to make that very suggestion. I use a Sonuus G2M into a Dark Energy and can tap both MIDI and CV from there. The G2M itself tracks guitar quite well, at least in a studio setting. Getting the synth dialed in can be a bit finicky but what in analog land isn't? 

The G2M goes for only about $100 so you can't go too far wrong. They also have a unit that does pitch to MIDI through USB that's also under $100.

Has anyone thought about using one of the cheaper guitar pitch to MIDI converters (such as the one by Sonuus), then straight into a MIDI/CV module? That could work....

Thank you Florian. I'll have a look at the schematics when I have time. At the moment I'm about to prepare everything for the
Superbooth in Berlin end of March. I want to show a couple of new modules (in addition to the modules presented at NAMM).
