<<I believe you could be happy with any of these systems. The exciting

Wiard:

The Omni filter can work as a phaser (allpass mode). It has 1v/o-calibrated
and attenuatable exponential inputs, att. linear input (FM), either positive
or negative feedback, has outputs shifted by 360 degrees (two poles) and by
720 degrees (four poles) and can be crossfaded into highpass filtering mode.

Frequency shifting can be realized to a limited extent if you have two Dual
Envelators, four (sic) Wavecities and two Mixolators: shape both quadrature
related Envelator triangle outputs to sinewaves, ringmodulate the respective
sine and cosine signals and add/ subtract for single sideband outputs.
However the Envelators are controlled linearly for most of the audio range,
the sinewaves won't be perfect and the Mixolator ringmod function is not the
quietest around.

Variable slope filtering (between 12dB/o and 24dB/o) can be done either with
a crossfade between the Omni two pole and four pole outputs (as mentioned in
the phaser reply), or with a crossfade of the two Dual Borg Filter outputs
if they are patched in series.

Each Envelator section can be used as CV divider. During the attack phase
they do not retrigger so raising attack when the trigger input is a wave
below 500 Hz will make the Env. output any whole number division of the
input in length until the Env. maximum slope time is reached. (I don't know
what the output will be if the trigger is above this frequency.) There is
not only a pulse output as with most other dividers (e.g. Serge) but also
the slope output which is shape-stretched as the attack setting approaches
the next whole number.


You see, the Wiard is far more powerful than obvious at second or even third
sight. Also, one often is somewhat deceived by the "6-module-system"
concept - owning a "double system" will multiply the capability by a
trillion (as seen from the frequency shift setup for example). Grant has
realized this by now and tries to lay off the system approach.

Divider and Boolean Logic module have been added by Rex.>>

This is incorrect. Only 2 Wavecities are required: for a near sinusoidial (8
bit approximation) carrier. For sub-audio frequency shifts however (through
zero "barberpole" phasing effect), the variable triangular Envelator outputs
can be used withoput sineshaping. So all required for a limited range of
interesting frequency shift sounds (for example: FM the Envelator which
plays the modulator) is a double Wiard system.
