[sdiy] Combined CV/Gate on a cable

[Gene Stopp]

Back in the 80's a friend of mine built a stretched wooden case for a
Minimoog and had me build a 5-octave keyboard into it. I made a digital
scanner/DAC CV interface and created a bunch of option switches for it -
highnote/lownote priority, linear/expo glide, up only/down only/both
direction glide, and single/multiple trigger. For the multiple trigger, I
differentiated the CV to create a trigger and used that to "glitch" the gate
by pulling it to ground with the open collector output of an LM339.

It worked great, so here's at least one vote in favor. I think if the
release time is anything but zero, the new attack will just build on the
existing sustain level, as Rene says.

Hi all,

I guess this depends on the design, but the envelopes I use do that, if 
there is a tiny portion where the gate goes back to zero at the start of 
the new note. (Thus resetting the internal flipflop.) The output of the 
envelope doesn't have the time to change significantly in that time.

Cheers,
