* simpler method adopted (pointer vs producerMessage etc)
* better tooltips

Muxlicer:
* address in can only adjust step on clock ticks

* changed polyphony logic (we don't want to "broadcast" monophonic
  channels in the mixer, as downstream these will be summed via
  getVoltageSum, see e.g. VCMixer in Fundamental)

* ADSR: added missing .svg, and removed unused variable

* more efficient crossfade function
* correcting crossfade CV logic
* added "differences from hardware section"
