FR: Make Audio Dispatcher morph/scanable

[docbot]

I love Mulab but sometimes are missing some more niche features that one would use if you're into modular.

Would be very handy there was a module that works like the Audio Dispatcher, but with a slider that controls where the signal is being output to, fading/morphing between them.

so you could fade a signal between 8 speakers/outputs by simply turning a knob. Not just very handy for multichannel speaker performances, but also for building wierd matrix mixer like effect routings.

Feels like it might not be that hard to implement? basically a knob that fades a input signal between multiple outputs

pretty please Jo!
