Partials & Discrepancies

Partials & Discrepancies is an 8-voice additive polysynth built around one additive oscillator per voice, with up to 128 partials per voice, slot-based timbre motion, and deliberate divergence between voices. It was made as a more disharmonic and experimental companion to Curves & Membranes, but still with a layout where you can actually follow what is happening and stay close to the sound while it shifts.

Each slot stores a full partial shape with seven node handles plus six behavior parameters, so the sound can move between harmonic and more broken states. Offset, Wave Warp, and Weirdness push the partials away from neat spacing, while the slot sequencer, voice offset, and discrepancy controls let voices drift, diverge, and sometimes misbehave in very musical ways. It is good for animated additive pads, unstable leads, brittle digital choirs, and inharmonic sweeps that still stay playable.

It is not trying to be a conventional polysynth with a different paint job. The point is to put the additive structure, slot motion, and voice divergence right in front of you, so the sound can get weird while the workflow stays readable.

Highlights:

• 8-voice additive synth.
• up to 128 partials per voice.
• slot sequencer for timbre motion.
• discrepancy controls for controlled voice drift.
• MTS-ESP support.
• MPE compatibility.

Good fit for:

• additive synthesis with a quick and readable interface.
• harmonic exploration that can drift into stranger territory.
• synth parts with motion.
