Re: Vortex CV control

Re: Vortex CV control

1999-10-28 by Paul R Bower

hello all
for CV control of a Lexicon Vortex via the pedal input:
wire a TRS jack Tip=signal / Ring=not connected / Sleeve=screen
the Ring sends a +5v source from the Vortex - the service manual claims "a
50k pot will sweep the full range". As far as CV control of Vortex goes, it
says "control voltage can be used but only 0-5v will apply instead of 0-10v.
voltages over 5v will be tied to 5v"
i must admit, i've not done it for ages, but with nice long lfo... ...well
you can imagine

glad you (thomas) like the FFWD album, the 3D effect is likely to come from
a Cyclosonic Panner (by "Songbird" i think) it was a bit of an Orb favourite

meanwhile, I can announce the winners of the FFWD competition, while I was
cursing away at a little red box, David Bivins said yes (erm i'll need your
address matey), and a certain Mr Schreiber contacted me...

Geez. I didn't know I could control it via CV. Thanks for the info.
Besides the
LFO I can imagine some pretty sweet sounds using an envelope follower
with
guitar and slow release. You just breathed new life into an already fun
unit.
I wonder how fast it can respond (thinking of FM morphing...)

Thanks,
Thomas
