Zebralette 3 Additive Engine Discussion – Page 4 – u-he Forum

Is it currently possible to set partials to semitone distribution, in various divisions?

Example would be Harmor in “oct” mode:

I haven’t yet found a way to do this in Zebralette 3. I’ve tried Spectral Dist with Curve as Modifier, using rising log-like curve, but the partials never settle exactly on semitones. Also, the distribution of partials in pitch dimension seems to always be based on harmonic series, resulting in denser partials at higher frequencies.

If per-semitone (or semitone-relative, however it’s called) partial distribution mode was not part of the design, I’d suggest that to be added – preferably to both wavetable and additive renderer, and modifiable with curves (if feasible). It’s a good basis for controllable creation of inharmonic sounds and various chordlike timbres.

In any case, it’s awesome to see new developments in area of user-programmable additive synthesis. Many thanks to fellows at u-he for efforts past, current and upcoming, and congratulations on getting the beta out!
