Zira, Specs and features
| 2 Oscs: | Each with 48 waveforms, I picked 48 of my favourites from the Monowave. A sub oscillator, linked to oscillator one. The Sub oscillator has a level control, oscillators one and two can be switched on or off.
Note offset for Patch +/- two octaves, second oscillator has note detune of +/- two octaves and fine tune. Hard Sync of oscillator two to oscillator one's pitch. | |
| VCF: | The Korg NJM2069AD is used in the prototypes for the filter. This 4-pole low pass filter is the same filter chip used in the Poly800, DW8000, DW6000 and DSS-1 | |
| VCA: | Very high signal to noise ratio and incredibly clean sounding, again, the prototype uses the NJM2069AD. | |
| EG's: | One for Filter and one for VCA, both are ADSR type. They have Linear attack and exponential decay and release curves.
These go from very quick (~3mS) to a many seconds for each stage (~48 Seconds). |
|
| LFO: | The LFO has 4 wave forms, Sinewave, sawtooth, square and random. the LFO is routable to oscillator pitch, filter cut off and filter resonance.
A delay parameter allows the LFO to come "fade in" with an adjustable delay. It also has a key sync mode, when on the LFO is forced to reset when a new key is pressed and when the LFO cycle has finished it rests at that value. |
|
| Display: | The display uses four 7 segment displays, the same as GorF and Tron. | |
| MIDI | MIDI CC for each parameter, receipt of Patch change (64 patches). | |
| I/O: | The Connections could not be simpler, power in (6 to 12V DC), MIDI in and Audio out. |
Menus
Left to right button functions ;
Load, Save, Edit, Quick
- Pushing Load button lets you use the two left hand knobs to select bank and patch, press load again to load that patch, any other button exists load mode.
- Pushing the Save button lets you use the two left hand knobs to select bank and patch, press Save again to Save that patch, any other button exists Save mode.
- Pushing the Edit button takes you through the menus below.
- Pushing the quick button drops you to the quick edit mode, where the four knobs are assigned by the user. These are stored with each patch.

There are four "quick" edit parameters which are userdefineable.
The parameters are stored per patch (8 banks of 8) the "global" parameters are stored globally.
Global Parameters
The following parameters are accessed by holding Edit and Quick Buttons together.
| Menu Name | Knob 1 | Knob 2 | Knob 3 | Knob 4 |
| Global | MIDI Channel 0 - 15 | Tune -63 to +63 | Bend Range 0 to 24 |
