Two voltage controlled discrete analog oscillators, one sub wave of Oscillator 1, waveforms: sine (OSC 1), triangle, sawtooth and variable width square; simultaneous waveforms output; syncing of Osc 2 to Osc 1.


Two voltage controlled discrete analog filters: 12 db (classic Oberheim® style) hard-wired into voice board; 24db (classic Moog® style) in docking slot 1; 2 additional filter docking slots; 2 and 3 can host our classic Roland® 303, Arp® 2600, and Yamaha® CS-80 styled, all hardware filters; 12db filter modes: low pass, bandpass, high pass and band reject. Filters do not operate in series or parallel. Each voice can access all four filters.

Filter Control Section:

Sweep through all the filter types in real time.
Increase or decrease the filter frequency.
Increase the envelope amount.
Increase the resonance amount.
Filter ENV Delay.
Invert the filter envelope.
"CUT" Filter Decay.
Controls CODE synth engine or external input.

Filter Control Sequences for the filter tables:

SEM LP = 1
SEM BP = 2
SEM HP = 3
MINI = 5
AUX 1 = 6
AUX 2 = 7

For Units with SEM and MINI:


For Units with SEM, MINI and AUX1 (filter slot 3):


For Units with SEM, MINI, AUX1 and AUX2 (filter slot 4):


The Mono Version:

configured as a single input mono filterbank.

The 2 Voice Version:

configured as a dual input stereo filterbank.

The 4 Voice Version:

configured as a 4 input or quad filterbank.

The 8 Voice Version:

configured as an 8 channel filterbank.

Each voice card has two empty expansion slots for extra filters: the S.E.M. filter is built in and the Mini filter sits in expansion slot 1; three expansion slots total, as is the case for all Omega Series Synths.

Optional filter cards also available:


Patch Bank 3

Includes Theriot bank ($139 sold separately)

Patch Bank 4

Includes Cadix bank ($189 sold separately)


Three multiple stage envelope generators: attack, decay, sustain and release with inverting and multiple triggering; additional delay, decay 2, and breakpoint parameters for envelopes 1 and 2; assignable 3rd envelope with up to three destinations and depths. Envelope 1 fixed to filter frequency. Envelope 2 fixed to amplifier level. Envelope 3 knobs also can control the external inputs.


Three low frequency oscillators, waveforms: triangle, sawtooth, reverse sawtooth, square, noise, random; three destinations and depths each for LFOs 1&2, with range, delay, key trigger, phase, mode (mono or poly), quantize, midi sync. LFO3 fixed to voice panning.


Linear or exponential, parameters: time, mode (auto, legato, glissando), autoglide interval, dynamics, destination.

Unison Mode:

One, two, four, six, or eight voices depending on voice configuration.

Multi Mode:

Prepared: one MIDI channel, up to eight different patches (synths); split: set point; layer: 4-4; multi: channelize up to 8 patches (synths).

Additional Features:

Oscillator 2 audio frequency modulation, destinations: OSC 1 frequency, OSC 1 pulse width, filter frequency; white noise generator; auto triggering external input processor on each voice, parameters: input level, trigger level, mix level, window.

Modulation Destinations:

LFOs 1, 2 and envelope 3: VCO 1 and 2 frequency, pulse width, and mix level, VCF frequency and resonance, noise level, Xmod amount, LFOs 1 and 2 rate and depth, VCA level, external mix level.

MIDI Controllers:

Dynamics, modwheel, bender, pressure, tracking, breath controller: LFOs 1, 2 and envelope 3 destinations, including envelopes 1, 2, and 3 attack, decay, sustain, release amounts.

MIDI Specifications:

In out and thru. Receives program change, bank select, glide on/off, glide time, volume, SYSEX. Controllers: dynamics, modwheel, bender, pressure destination and amount (x2). Controller 1 assignments: dyn, mod, pressure, bend, tracking, continuous cont #2 (x2), controller 1 amount (x2). Controller 2 assignments: same as controller 1 (x2), controller 2 amount (x2). Dynamics, tracking, and bender can manipulate positive and negative modulation values. Fixed continuous controller assignments exist for all key functions.
