Dave Smith Instruments SYNTHESIZERS

I am definitely experiencing jumping. Its just like my other polys or monos with memory (like the moog voyager) in that respect. Particularly noticable when I grab the filter cutoff paramter knob. But I offered tat as a possible explanation for why, in poly chain mode, my "basic patch" edit resulted in 2 different sounds for the 4 voices of the keys and rack.

When you adjust a parameter on the PEK, I thought the sysex message[*]
sent over the polychain output was an absolute setting for that
parameter, which would force the rack to the same value as the keyboard
-- even if they started out with different values.

[*] "Program Parameter", p.53 in the PEK manual

[BTW, AFAIK the PEK uses encoders, not pots, so all knob edits should be
relative on the keyboard side, i.e., no jumping.]

So does the PEK not use encoders then?  Does it use ordinary pots?

[Seems like it wouldn't affect poly-chain synchronization either way
though, if the parameter sent over midi is absolute.]

Thanks,

The PEK has endless rotary encoders.  I have not experienced any
'jumping' with mine, though there is a certain amount of stepping,
which becomes more noticible as resonance is increased or distortion
is on.  You tend to get that when you have analog circuitry under
digital control, and a top to bottom resolution of 164 steps..

there is no stepping of this kind with the envelopes or LFO's.  just
direct patch manipulation causes it.
