Zira Demonstration
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
