Yes. I had a bit of a hard time following the signal flow (a problem I have with many complex patches created by other people for ER-301). I kinda got the impression that perhaps a global chain containing an ADSR envelope is modulating itself?
I thought I’d ask for some English language description before I dived deeper into that patch and inevitably diagrammed it out in order to grok the flow, but that’ll be my next step I suppose.
Right - understandable. Me too sometimes. It is probably simpler to achieve now anyway.
For a random trigger, go to a global chain and do velvet noise–>recitifier (positive half) → skewed sine envelope. You can set the frequency on the velvet noise nice and low for Krell type stuff. Try using that to trigger your main amp vca envelope back on the channel chain as a start.
Since there is no EOC trigger on an envelope and not a very good way to route it if there were right now, you could use this exact same global chain to trigger the other S&Hs that are triggered by the EOC trigger in the diagram above. You could use the micro delay (udelay) unit on the main amplitude VCA env if you needed a very small amount of time to allow the other parameters to get set. I think this would work.
