Patch Ideas: Analog Signal Processing, Voltage MATHS!
ADD, Subtract Control Signals
Apply signals to be added/ subtracted to any combination of Signal IN CH. 1,2,3,4 (when using CH. 1,4 RISE
and FALL must be set to full CCW, and Cycle switch not engaged). For channels to be added, set
Attenuvertor controls to full CW. Set Attenuvertors for channels to be subtracted to full CCW. Take output
from SUM OUT.
VC Portamento/ LAG/ Slew Processor
A signal applied to the Signal IN, is slewed according to the RISE and FALL parameters. Variable response
from Log thru Linear to Exponential, is as set by the Vari-Response panel Control. The resulting function may
be further processed with attenuation and/ or inversion by the Attenuator Panel Control.
Envelope Follower
Apply Signal to be followed to Signal IN CH. 1 or 4. Set RISE to NOON. Set and or modulate FALL Time to
achieve different responses. Take output from associated channel Signal OUT for positive and negative Peak
Detection. Take output from OR buss OUT to achieve more typical Positive Envelope Follower function.
Peak Detector
Patch signal to be detected to CH. 1 Signal IN. Set RISE and FALL to 3 'o' Clock. Take
output from Signal OUT. Gate out from EOR OUT.
Voltage Mirror
Apply Control Signal to be mirrored to CH. 2 Signal IN. Set CH. 2 Attenuvertor to Full CCW. With nothing
inserted at CH. 3 Signal IN (so as to generate an offset), set CH. 3 Attenuvertor to full CW. Take output from
SUM OUT.
Voltage Comparator/ Gate Extraction w/ variable width
Apply signal to be compared to CH. 3 Signal IN. Set Attenuvertor to greater than 50%. Use CH. 2 for
comparing voltage (with or without something patched). Patch SUM OUT to CH. 1 Signal IN. Set CH. 1 RISE
and FALL to full CCW. Take extracted Gate from EOR. CH. 3 Attenuvertor acts as the input level setting,
applicable values being between NOON and Full CW. CH. 2 acts as the threshold setting applicable values
being from Full CCW to NOON. Values closer to NOON will be LOWER thresholds. Setting the RISE more
CW, you will be able to Delay the derived gate. Setting FALL more CW you will vary the width of the derived
Gate. Use CH. 4 for Envelope Follower patch, and CH. 3, 2 & 1 for Gate extraction, and you have a very
powerful system for external signal processing.
Half Wave Rectification
Apply bi-polar signal to CH. 1, 2, 3, 4 IN. Take output from OR out. Mind the normalizations
to the OR buss.
Full Wave Rectification
Mult signal to be rectified to both CH. 2 and 3 IN. CH 2 Scaling/ Inversion set to Full CW,
CH. 3 Scaling/ Inversion set to Full CCW. Take output from OR Out. Vary the Scaling.
Multiplication
Apply positive going control signal to be multiplied to CH1 or 4 Signal IN. Set RISE to full
CW, FALL to Full CCW. Apply positive going, multiplier Control Signal to BOTH Control IN.
Take output from corresponding Signal OUT.
