hmmm, i will look into it this morning. clicking while panning is definitely not the intended behavior 
edit: so i was able to repro the clicks, not sure exactly what the root cause is, but setting the pan slew param to a non zero value (per voice) fixes it.
i’ll push a change to the default pan slew amount as a fix.
edit the second: pan slew update pushed. update via the maiden project manager.
