[sdiy] Module idea - you guys get to work (for me!)

[Peter Grenader]

What I'm into...well, what I'm into in regard to sound synthesis anyway (ha
ha - but see a funny antidote on this at the bottom of this post) is having
controls track one another.

Let's say you've got a patch going with two VCOs tuned 'close' to unison.
If you do NOT sync your VCOs (I rarely do this) and tune them just so to get
that marvelous sweeping phase cancellation, wouldn't it be nice to pan the
sound across the stereo field with that?  Or sync a filter opening with
these?

That sort of thing.  This patch allows you to do this.

Now, getting back to 'what I'm into'.  When Jon Appleton accepted his SEAMUS
Lifetime Achievement Award last year at ASU,  he spoke a bit about the
halycon days and bringing it back to 'modern day' he mentioned he 'hated
plug-ins, unless you're speaking in the sexual sense of course"...

Pretty phunny for a bunch of academics.
