Overload Audio has announced the release of a free 6-voice polyphonic synthesizer modeled on the 1981 Korg Polysix.
Like the original, MOODYSIX features one oscillator per voice with saw, pulse width, and PWM waveforms, a sub oscillator, the iconic SSM2044-style 4-pole lowpass filter, and the legendary chorus/phaser/ensemble effects section. The synth also comes with 3 classic hardware mods:
- NoisySix: Adds white and pink noise generators plus an extended MG (LFO) with triangle, saw up, saw down, square, sample & hold, and noise shapes. Variable pulse width for the square LFO.
- Polysex: Pitch envelope modulation with polarity and reference controls. Voice spread with EG and LFO modulation for thick detuned sounds.
- ModyPoly: Smooth portamento/glide that works properly across all voice modes including unison.
Just like the original you will feel the oscillators warm up when you turn it on this VST as it moves into tune, the crisp SSM2044 filters sweep and the light parameters warbling ever so slightly give an organic movement – No two notes sound quite the same, just like on the VCOs.
And also like the original Polysix, the MOODYSIX does not respond to velocity and is strictly 6 voices – this is to stay true to character of this synth.
MOODYSIX features
- 6-voice polyphonic with poly, 2-voice unison, 3-voice unison, and 6-voice mono modes.
- Saw, pulse width, and PWM waveforms with dedicated PWM LFO.
- Sub oscillator (1 or 2 octaves down).
- 4-pole lowpass filter with resonance, EG intensity (bipolar), and key tracking.
- ADSR envelope for filter, amplitude and added pitch and voice pitch spread envelope.
- MG (LFO) with delay, routable to VCO, VCF, VCA as well as voice pitch spread, with additional MG shapes via the noise section.
- Chorus, phaser, and ensemble effects (Triple BBD-modeled).
- Arpeggiator with up/down/up-down modes, 1/2/full octave range, and latch.
- Hold and chord memory.
- 32 factory presets.
- Portamento with per-voice glide.
The synth is a “pay what you like” download, available in VST3 and AU plugin formats for Windows and macOS.
