COLD MAC

Whimsical Raps (Mannequins)

Analog utilities with creative mixing and patch surveillance. Combines classic analog computing elements with unified control: 6-input mixer with VCA, VCA/PAN/CROSSFADE, analog logic (OR/AND), envelope follower, wavefolder (CREASE), integrator (LOCATION), and Patch Surveillance meta-control via SURVEY.411

Capabilities 7

Analog Logicanalog-logic
OR (Maximum/Peak) and AND (Minimum/Trough) perform analog logic comparisons on two inputs, normalled to SURVEY as the compare value.411
Envelope Followerenvelope-follower
FOLLOW input/output tracks the envelope of any signal for sidechaining; sending a trigger/gate creates a simple envelope.411
Integrator (LOCATION)integrator
LOCATION integrates input voltage; output slowly shifts toward input direction and freezes at 0V input.411
Mixermixer
Mixes up to 6 inputs (left-column jacks) into MAC output with SURVEY-controlled linear VCA; AC coupled so CV is not mixed.411
Voltage-Controlled Amplifiervca
SURVEY knob (or CV) provides linear VCA over the entire 6-input mix at MAC output.411
Voltage-Controlled Crossfadercrossfader
LEFT/RIGHT input/output block implements VCA, pan, or crossfade depending on which jacks are patched; FADE input decouples from global SURVEY.411
Wavefolderwavefolder
CREASE input/output applies amplitude-sensitive wavefolding to audio or induces discontinuities in CV. In Patch Surveillance mode CREASE is one of 8 transfer function outputs.411

Jacks 21 — 12 in / 9 out

NameSignalVoltageDescription
Inputs (12)
AND(1)mixedPrimary input to AND (Minimum/Trough) function. Normalled to OR(1) per normalled connections list.411
AND(2)cvSecond input to AND (Minimum/Trough); normalled to SURVEY per normalled connections list.411
CREASE (input)mixedInput to CREASE wavefolder/discontinuity function. SLOPE has 2x gain into MAC when CREASE is unpatched.411
FADEcvCV input to control the pan/crossfade position directly, delinking from global SURVEY control.411
FOLLOW (input)mixedEnvelope follower input; also responds to trigger/gate to create a simple envelope. Normalled: FOLLOW to SURVEY.411
LEFT (input)mixed411
LOCATION (input)cvIntegrator input; output slowly shifts toward input voltage, freezes at 0V. Larger inputs move more quickly.411
OR(1)mixedPrimary input to OR (Maximum/Peak) function. Normalled: OR(1) to GROUND per normalled connections list. Also has 2x gain into MAC when AND(1) is unpatched.411
OR(2)mixedSecond input to OR (Maximum/Peak); normalled to SURVEY per normalled connections list.411
RIGHT (input)mixed411
SLOPE (input)mixed411
SURVEY CVcvCV control over SURVEY; knob position adds as offset. Accepts slow CVs through audio-rate modulations.411
Outputs (9)
AND (output)mixedOutput of AND (Minimum/Trough) function — the lower of the two AND inputs.411
CREASE (output)mixedOutput of CREASE wavefolder: amplitude-sensitive wavefold for audio, or discontinuity inducer for CV.411
FOLLOW (output)mixedEnvelope follower output; responds to audio for sidechaining or to trigger/gate for simple envelope generation.411
LEFT (output)mixed411
LOCATION (output)cvIntegrator output; slowly follows the trend of the input voltage toward the input direction, freezes at 0V input.411
MACmixedMix output of all 6 left-edge inputs, with SURVEY controlling a linear VCA over the entire mix. AC coupled — does not mix CV signals.411
OR (output)mixedOutput of OR (Maximum/Peak) function — the higher of the two OR inputs.411
RIGHT (output)mixed411
SLOPE (output)mixed411

Parameters 1

NameTypeRangeBehavior
SURVEYknobMeta-control for the entire module; controls the linear VCA over the MAC mix, the pan/crossfade position (normalled to FADE), the compare value in OR and AND, and SLOPE. In Patch Surveillance mode (no left-column inputs), the 8 shaded outputs provide different transfer functions of SURVEY. The CV input adds to the knob position as an offset.411
