Odin 2

A free, open-source 24-voice polyphonic synth with analog-style oscillators, classic filter emulations and five built-in effects.
Odin 2 is a 24-voice polyphonic synthesizer that combines analog-style waveforms with emulations of classic filters like the Moog ladder and Korg 35. It has five onboard effects and a broad modulation system, so you can get from basic VA patches to fairly involved sound design without leaving the plugin. The whole project is open source under GPL-3.0.
