Easing up on the depth of the LFO controlling the pulse width will reduce the nasties.

The assignable knobs can be used to mix the volumes of each zone polyphonically in real time in performance mode, but shouldn't this also be possible in the mixer? Then the assignable knobs can be used for other things. The mixer works this way in the step sequencer, but not in a performance. By "solo mode", I was referring to "solo mode" as mentioned on page E-68 of the P1 manual and page E-79 of the G1 manual, not the solo synth. These pages suggest that "solo mode" is available for all channels 1-16, i.e., zones 1-4 in performance mode as well as parts 8-16 in the step sequencer. Which means that "solo mode" can be switched on to sound a part monophonically, and switched off to hear the part polyphonically in the whole mix. I can't seem to switch solo mode off during a performance and mix all four zones polyphonically.

With the mixer in performance mode, can I use sliders 1-4 as faders for zones 1-4? I am able change the volume (and other parameters) of each zone independently/monophonically, but can I do it polyphonically in real time? I seem to be able to do this OK for parts 8-16 while in the step sequencer, but I can't get it to work for parts 1-4. This would be very useful for fine tuning sounds in performance mode. There is something called “solo mode” in the mixer, but it makes no difference whether it's on or off.

Can't the LPF be used to reduce the "graininess" and other artifacts? I agree that PWM-L and PWM-B sound better than PWM.

Mild delay is a good suggestion. I've just discovered another method, at least on the G1, using the sample looper. Record the desired tone in the sample looper, leaving a second or so of silence before playing it, then adjust the user wave start point parameter to control the onset timing. Seems to work. More generally, it would be nice to have another envelope parameter called something like "init time".

Is it possible to control the onset/trigger timing of a tone? I'm thinking of a situation in Performance Mode (or maybe hex layer) in which one key press triggers different tones that are slightly staggered in their timing, i.e., the attacks start at different times. This would allow greater experimentation with the harmonics of different tones, or maybe even the same tone.
