stable "swell" effect

SUPER MUSCLE release 0.1.05

more-or less stable swell-effect function

So the swell effect works like this:
instruments (here: toms) send MIDI control changes to microKORG to control cutoff, resonance and sustain.
The notes are triggered automatically upon the SECOND hit of one of the instruments.
Each hit on the any of the instruments increases the instrument-specific MIDI-CC. Automatically, the values decrease with every beat the instruments are not hit, until CC values are 0 again. Then, the MIDI notes are turned off, too.

TO DO:

• implement footswitch to hold CC values (toggle)
• set CC-specific decrease-values so that the playing becomes more dynamic.
