[sdiy] trying to understand appregiators in late 70's synths

[Paul Maddox]

Dan,

yep, though you need make sure it doesn't invert at the same time :-)
You can do the same with MIDI, check out the demo video of GorF (http://www.zoybar.net/video/gorf-019 
) at around 1:35, it's quite handy to be able to do.
