VacoLoco Zira

VacoLoco Zira

The Zira is more or less a mini version of the Modulus monoWave. The project by Paul Maddox, the creator of the MonoWave and co-founder of Modal Electronics, was originally named PicaWave (see lower left of the red PCB) and was later renamed to Zira. It got the same two digital oscillators as the MonoWave, but with "only" 48 digital waveshapes. There is one sub-oscillator, hard sync, and one LFO with an fade-in parameter. The discrete ladder filter of the MonoWave was exchanged for a Korg NJM2069AD Filter/VCA chip (as found in the Korg Poly800, DW8000, DW6000 and DSS-1). The envelopes are both digital created. It uses 4 LED 8-segment displays and endless encoders for editing. You can save 64 patches on board. All housed in a clear housing sized 120 x 90 x 24 mm. It got connectors for power, Audio Out and MIDI In.
