Feature request: advanced retriggers - retrigger stretch & retrigger count

[hubweil]

2 things would make the retriggers even better:

• probability for retrigger count = randomize how many retriggers PER STEP are triggered
  by this it is not meant, IF a step plays retriggers or not, but HOW MANY

• retrigger stretch
  by this, the time, in which the retriggers are played could be stretched from very short bursts to slow trioles etc
  just like a drummer uses to vary the playing. The stretch could also be quantized to step(s)
  additionally, there could be also probability and RAMP parameters for it = speed up/slow down in time
