SPECIFICATONS
Construction
Sturdy steel chassis, 21 metal shaft pots, 8 knob-less plastic shaft pots, 18 chrome metal toggle switches, (16 three way for expanded functionality), Through hole circuit boards, AC power adaptor
Dimensions
Panel, 8.7" wide x 7" high, Height, 1.75" at front, 3.25" at back
Sound Generation
Discrete voltage controlled analog oscillators, filter, amplifier and envelopes. Hand matched transistors in filter and amplifier. No Curtis chips.
Oscillator 1
Center off switch for selection of individual or combination of sine, triangle,
saw and square waveforms, pulse width modulation by Envelope 1 and/or software LFO.
Two octave position sub square waveform. Bi-directional 1to2 or 2to1 oscillator sync. Five
position octave range switch. Modulation of frequency or pulse width by Oscillator 2 with
depth control.
Oscillator 2
Sine, saw or square waveform. Fine tune control. Six octave range switch with LO
frequency position. Keyboard tracking on/off switch. Modulation by Envelope 1 or Envelope 2
with depth control. Level control.
Noise Generator
Level control.
Ring Modulator
Level control.
Filter
Frequency and resonance with 1/3 or full keyboard tracking. Envelope modulation control. LFO or Oscillator 2 modulation control.
Filter Types
4075-classic Arp 2600, 5089-classic Moog 24db ladder, SEM-classic Oberheim 12db (full function, with LP to HP mix control), 303-classic Roland TB.
Envelopes
Four-stage with attack decay, sustain and release. Invert, loop and drone functions. In Master mode, Envelope 2 modulates both the Filter and Amplifier for simple, one envelope operation. Envelope 1 retains modulation control of other parameters. Single or multiple triggering of attack and decay stage. Envelope 1 dynamics control.
Amplifier
Two position overdrive. Volume control. Feedback control routes output back into filter and amplifier.
LFO
MIDI syncable software generated sine, triangle, saw, reverse saw, narrow, normal and wide square, random and slew random waveforms. Two speed delay function for LFO depth. Depth control for Oscillator 1 frequency or Oscillator 1 pulse width. Depth control for Oscillator 2 frequency or VCA level. Rate control, position determines sync division.
Additional features
Master tune, glide time and bend range controls, MIDI and power indicator leds, VCA clipping adjustment, ModWheel and Aftertouch control switch.
Patch points
VCO, VCF, VCA and gate inputs. External audio input. Envelope 2 and osc 1&2 pre-filter output.
MIDI Modulators
Volume, glide, modwheel to LFO, bender and dynamics. In, out and thru jacks.
