i've noticed a few different areas where audible high frequency artifacts appear. i don't know if fixing them is beyond the limits of the processor, or if they are purposely left in for extra "digital" character, or if there are any more significant firmware updates planned, but i'll document them here. i'm using 0.36.
1. knob zipper noise. i hear this on the overdrive in the mix section, when rapidly turning the drive knob. slewing the knob value would be a typical fix.
2. envelope noise. i hear this most pronounced on the snare and clap envelopes, set to zero repeats, with a moderately fast attack time.
3. auto-panning noise. this may essentially be the same as the first two since they all have to do with amplitude changes. if i set a sine or tri lfo to control panning, i hear zippers as it changes direction.
4. triangle phase offset. does the triangle waveform not start at zero? with no attack i hear a click at the start of the sound.
5. separate from number four, the already documented phase reset clicks on overlapping amplitude envelopes still exists. i program my envelopes around it, but it sneaks back in when i morph. no real workaround until the envelope level check gets implemented.
6. sine artifacts. i hear high frequencies in low sines, probably due to wavetable size or sample rate limitations. not a biggie for me.
there are probably other zippers and clicks having to do with lfos and amplitude that i havent noticed yet.
i enjoy some of the artifacting that happens. i appreciate the extreme ranges that allow intentional destruction (very low pitches, or parameter switching on kit morph for example), but it would be nice to see some of the simpler more obvious ones cleaned up.
i'd take a stab if i could get the tools to install on my ancient computer.
