[sdiy] What I'm building (update)

[Scott Stites]

Harry,

How about breadboarding the Korg PS series resonator and modulating each
filter from a phase of the tri-phase?  The Resonator's a fairly easy thing
to whip up if you have the Vactrols.  I've had Rene's tri-phase going, and
the resonator going, but neither at the same time.  It's something I've been
wanting to try for a while.

A year or two ago, I heard a sample Rene did with three VCOs which were
frequency modulated slightly with the tri-phase to embiggen the sound.
Sounded really, really nice.

Cheerio,
Scott
