Hi flabberbob, I understand how lfo pan modulation with the square wave should work, the problem I tried to describe is: when this waveform is selected, with the pan modulation knob set to 127 for instance, the trigger phase knob set to 127, with the panorama knob of the channel set to center, the phase should start on one the left side right? well this don't happen, there are a very short time (around 100ms) of sound on the left side before working properly; when sine or triangle wave selected with the same settings the phase should start at the center right, well this doesn't happen, neither, it start at one side every time.
About the unexpected change of volume, you were right I'm running VC in sequencer mode, but still, is something that never happen before, I mean with an early OS version, I haven't change anything in my setup, there is no automation or other kind of midi message that I deliberately had previously set to change that midi channel volume CC.
Finally, about the clicks/ticks its gonna be hard to record it because it doesn't happen to often, still I'll try to catch one, is something like a kick drum playing constant at 1/4 note but without the mid and bass frequencies, just the frequencies above 4 kHz, in other words from 4 kHz to 16 kHz, and some times just from 0 Hz to 125 Hz, the volume of this clicks use to be around -30dB in the channel meter. This click is not related to any specific channel or patch (I always create my own patches) I could turn down the volume of the 16 parts and the click/tick still coming in.
Thanks for the attention, cheers from Madrid!!
