It also has to do with the adjustable length of gate time, the Dreadbox based around it’s VCA, EGs & LFO. Without that, there would be no control over the frequency of the retriggering. For example, the LFO would be retriggered on each new input note that crossed the threshold level.
It’s a rare application of combined controllers. In a Beebo (probably Zoia or similar), it would start with an Onset Detect or Env Follower module – for the note trigger – split off to a Trigger To Gate module, with a gate hold parameter. And also split off to an LFO Reset. I suppose it can be done. I would think LFO Phase might get involved, as many will expect an LFO Retrigger to reset at the maximum height of the waveform.
It might be more straightforward to send a MIDI CC mapped to Retrigger from a sequencer.
