Zira Demonstration

April 21, 2012 · Posted in Uncategorized 

A quick run through of Zira and it’s features.

Background data:

Zira came out of an idea I had to see how small I could build a synth and still get it to sound good. The prototype is based on the Korg NJM2069AD Filter/VCA chip, the reason for this being I had 8 lying around I bought a while back from Korg to build a polysynth with.

There are a small number of these being made, I will be selling these as fully assembled modules with a case.

However, I fully intend to try and replace the NJM2069AD with a discrete filter and VCA of some kind (currently a 2 pole State Variable Filter based VCF and simple VCA is looking good) and turn this into kits in much the same way as I did with GorF.

A quick summary of it’s features;

  • Two oscillators, each with 48 waveforms
  • One Sub oscillator
  • Hard Sync of oscillators
  • Two ADSRs, one VCF, one VCA
  • One LFO
  • Multiple routing options
  • 64 patch memories
  • MIDI updatable firmware
