Thanks for the detailed write-up! Yes, gate high/low is what I meant.
1) is exactly what I tried. The problem is that the envelope stays in the sustain stage even when the pattern or the whole sequencer stops. Only double pressing shift-stop brings down the gate.
For 2) my problem is that I don't think I could achieve the correct re-trigger behavior that I need, i.e. that the voltage very briefly drops to zero before the gate is on again.
