Odin2 is a polyphonic synthesizer plugin designed for musicians who want a broad selection of sound-generation and modulation techniques in a single instrument. Its architecture covers traditional analogue-style tones as well as more experimental sound design.
An array of oscillator models and filters gives users different routes to shape a patch. Modulation controls can introduce gradual movement or sharply articulated changes, while built-in processing helps finish sounds without requiring an external effects chain.
Its combination of synthesis depth and an integrated step sequencer makes it useful for electronic leads, basses, pads and rhythmic textures.
This is free and open source software.
Key Features
- Three oscillators with multiple selectable synthesis models.
- Drawable and conventional oscillator waveforms for custom timbres.
- Three filter slots with analogue-inspired designs including ladder and Korg-style models.
- Up to 24 voices of polyphony and unison sound shaping.
- Four modulation envelopes and four low-frequency oscillators.
- Modulation matrix and XY pad for flexible parameter control.
- Dedicated distortion and onboard audio effects, including reverb.
- Arpeggiator and step sequencer for generating rhythmic patterns.
- Scala and keyboard-mapping file support for microtuning.
- Preset bank management and graphical sound editing.
- CLAP, LV2 and VST3 plugin formats on supported Linux hosts.
- Cross-platform support – runs on Linux, macOS, and Windows.
