Haven't been patching a lot lately, but had a very good time again yesterday night with my G2 and MS20. I always had some trigger issues; fast steady triggers were no problem, but triggers in a varying rythm did not work 100%. This has to do with the S-trig trigger inputs on an MS20; which need a constant high (>= +3V I believe) signal for a 'trigger off' message and a low signal or no signal at all for 'trigger on'.
I found out yesterday that by using a fast square osc with level converter (pos only), patched through a Behringer Mic100 preamp with the phase reverse button activated, gave a very reliable S-trig (OFF) signal. By interrupting this signal, an S-trig ON signal is given, also very reliably.
The strange thing is that if I use the level converter to make the square osc trig signal 'negative only' and deactivate the preamp phase reverse button (which should give the same result, right?) the triggering doesn't work anymore. Maybe another osc level bug, some asymmetric DC-prevention effect from the G2 DA convertors or a MIC100 thingie, I don't know yet.
I've included the patch for other peeps that use this combination. It is a really good combination (but I think I already hinted at that at the beginning of this patch )
Oh, and did I mention that there's no obvious reason why this shouldn't work on a NM classic? Can't check, but unless the different DACs behave very differently, it should work.
