Wiardgroup

Grant has posted terrific patch descriptions. I have to thank him
twice, actually. That's because the dome filter line in the quad
panning patch made me have a good laugh at my tedious "frequency
shifter" patch in the "Wiard_hints" text.

Actually, given one uses a custom waveform EPROM, one can make a
complete, easy to use frequency shifter, able to process any signal
(and including internal, 1v/oct controlled carrier VCO) with just two
Wavecities and two Mixolators. OUCH!! I guess no one read my erratic
previous idea or wanted to bother correcting me ;-)

Instead of gaining the required 90 degrees delayed versions of the
modulator and carrier by using Envelators PLUS shaping them to sine
waves with Wavecities, like I described before (and having a very
narrow sonic palette this way ;-), one can delay any carrier and
modulator with two Wavecities that contain a 90 degree delayed
ascending sawtooth.

Use the "Wave256" program to make a full amplitude ascending sawtooth
wave and shift it 90 degrees (or 64 samples) to the right (menu
"Warp", function "horizontal adjust").

(The rest, 2 x ringmodulating & mixing, remains the same of course. I
shall update my patch file soon.)

Note: I would expect the shifted sounds to show more than just 8 bit
Wavecity "grittyness" but also distortion because frequency shifters
want very precise sinewaves for carriers.
I wonder, will the "barber pole" endless phasing effect (made with a
subsonic carrier) show noticeable stepping, like the EMS frequency
shifter?

So if anyone tries frequency shifting with their Wiard setup, I would
be overjoyed to hear the results as I don't have an own system (my
order 16 months ago never made it to a transaction thanks to my own
and the "designer capriciousness" - nice term, Doc).

Regards,

Sebastian Kuehnl
