Free-running osc really free?

[CinningBao]

When one sets the oscillator's reset switch off, I would have expected to hear a different timbre on each keypress, when instead I hear the sound of an 8-stage phase cycle on each keypress.

Simple test:
one osc default saw
phase - reset off
mix - poly - dual/quad

is this how you intended the dual and quad modes to behave? Albino, for example, 'free-run's the oscillators as I would expect.

I'm not asking for 'that supersaw sound', just trying to figure out why it sounds like this

cheers!

Yeah, I was wondering a bit about that myself. However if you're going for supersaw you don't really need to mess with phase relationships specifically. Using the detune knobs, multiple oscs, panning/width control, and possibly chorus/delay, you can achieve some very phat supersaw sounds (I've done a bunch with Z2 so far). You can even try drawing in a doubled saw waveform as the base osc shape to get double the phat without increasing CPU much.

Yo, at the very beginning the oscillators are setup in a pseudo-random phase. So the first 16 notes you play with the same patch directly after opening an instance will have oscillators starting at identical phases (still each note starts at another phase).

Thing is, oscillators that don't sound (i.e. are part of inaudible voices or aren't activated) will not be processed, thus saving a lot of cpu. So, strictly spoken they are not free running. But when a new note is started, each oscillator keeps on running at the phase it was left, unless Reset is on.

However, lemme check it out. Bugs are subject to lurk at unexpected places, one never knows...

I wasn't

interesting - all the notes in the sequence were exactly the same length - this may account for the apparent cycling of phases. (testing required)
