Additive Synth Sound Design | 10 New Partials & Discrepancies Presets for the coming update

"Ten new additive synth presets from the upcoming Partials & Discrepancies 1.3.2 update.

No talking in this one, just sound examples. The patches focus mainly on two new features: X-Voice FM and Velocity Position, with sounds ranging from restrained and cinematic pads to noisier textures, keyboard sounds, and a more percussive patch.

X-Voice FM lets each synth voice FM-modulate the next voice in a circular chain. It can use either the previous voice’s filtered signal or oscillator output as the modulation source, and the FM amount is stored independently in every oscillator slot.

That means the amount of FM can move and slew together with the rest of the patch.

Velocity Position lets note velocity select the position, or an interpolated position, between the active oscillator slots.

So playing dynamics can change much more than volume. Depending on the patch, velocity can move between different partial structures, harmonic relationships, X-Voice FM amounts, or combinations of all three.

The result can be quite expressive with surprisingly little movement from the player.

The update also adds Live View, which follows an active voice in the waveform editor and shows its slewed node geometry, partial settings, and slot position in real time.

There are also new waveform-editing shortcuts, multi-step undo/redo, slot copy/paste keyboard shortcuts, and a fairly substantial round of interface-performance and stability work. (But more on that on the website when the release is here)

Partials & Discrepancies 1.3.2 is expected to be available on September 1, 2026."
