CRB Diamond Voco-Strings Schematic

Schematic below for this extremely rare (and extremely good) Italian analogue vocoder and string synth.

We’ve had two Voco Strings through our hands in recent years – one is part of our studio collection, and the other was being serviced for a good customer.


If you have one of these synths to sell please get in touch!


We’ll add more about this and other rare pieces we’ve come across to the site when we get time. Definitely want to get some demos up of these elusive beasts.


What you have is a four-octave polyphonic multi-instrument keyboard synth. Sections are:

  • Strings - cello, viola, violin
  • Chorus - male & female voices
  • Vocoder
