Scanner 69B smoothly cross-fades or pans between 8 audio or CV signals, 2 channels at a time. Scanning rate is controlled by an internal VCO or an external CV for direct positioning.
Also a clock pulse (or LFO) can be used to sync the scan frequency
in a similar manner to that on the Quad LFO 61B. Divisions and multiples of the clock frequency are also available using the rate control pot.
Scan frequency ranges from .016Hz to 400Hz using the internal
VCO, with a wider range possible using the CV Scan input.
Using the CV scan mode it is possible to use a random or cosine random
control signal to create random scan patterns as well.
The shape of the wave controls the scan order in this mode.
The internal VCO provides a continuous ultra smooth circular scanning loop which is not possible with traditional designs. For a circular scan they would require a sawtooth CV which would glitch on the reset slope.
Other features include CV and pot control of scan start position or offset from 1, and Span or number of inputs to be scanned from 2-8.
Scan direction (L-R or R-L) is controlled by the Rate Pot and DIR jack
and the unit also includes an amplitude jack for CV or envelope control of final out level.
It has both Linear and Audio pan response curves as well as a switch
mode that allows it to be used like an 8:1 or 4:2 switch with rate and CV controls.
Switch selectable input between Audio (AC) and low freq CV (DC)
There are many possible uses for this module including:
Audio rate Linear interpolation of waves for audio and control
Multiple input panning and cross-fading
Vibrato effects like an organ scanner.
Scanning Delay and doppler type effects produce interesting results
Scan through the 8 filter responses on the Matrix Filter
Scan through multiple LFOs to produce wild modulation patterns
