Free Korg Polysix Inspired Synthesizer
MOODYSIX is a 6-voice polyphonic virtual analog synthesizer inspired by the legendary 1981 Korg Polysix.
It recreates:
- the warm drifting VCO behavior
- the iconic SSM2044-style filter
- the lush ensemble/chorus effects
…but also includes several famous hardware mods that massively expand the original synth.
And yes — it’s currently FREE.
