Utilities

WR-CP35

The WR-CP35 console panel - four chain-normalled attenuators, two passive mults, and +/- 6 V references.

The WR-CP35

The WR-CP35 is a passive utility panel that combines four attenuators, two passive multiples, and two static reference voltage outputs at +6 V and -6 V. No DSP, no oscillators, no voltage control - just scaling knobs, fan-out jacks, and DC reference outputs.

The four attenuator section uses chain normalling. Patch a signal into INPUT 1 only and the same source drives all four outputs - each scaled by its own knob. Patch a different source into INPUT 2 and the chain breaks at that point: outputs 2, 3, 4 follow the new source while output 1 stays on the first. Patch into INPUT 3 and the break shifts again. The cabling itself becomes the routing logic - one cable in gives four scaled copies, two cables split the chain into two scaled groups.

The two reference voltage outputs (+6 V and -6 V) are static DC sources useful as bias voltages - pre-load a VCA so it idles at unity gain, anchor a filter cutoff so an envelope modulates around a known offset, or transpose a sequencer's pitch CV by a fixed amount. The two passive multiple banks are 1-to-3 fan-outs, electrically independent of the attenuator section.

The WR-CP35

The WR-CP35 has four att knobs (A1 ... A4, linear 0-1, default 0.5). Six inputs (I1 ... I4, MA, MB) and twelve outputs: four chain-normalled attenuator outputs (O1 ... O4), two banks of three mult outs (A1 ... A3, B1 ... B3), and the two static references (+6V, -6V). Chain normalling: each unpatched input inherits from the most recent patched input above it, so I1 alone drives all four outputs while patching I3 splits the chain (O1, O2 follow I1; O3, O4 follow I3). Mult banks are independent 1-to-3 splitters. References are constant +6 V and -6 V DC sources.

In a patch

Most-used patch: an LFO into I1, take out four copies through the chain-normalled outputs at different attenuation levels - one for subtle pitch vibrato, one for deeper filter wobble, one for a touch of tremolo on a VCA, one for a panning destination. One LFO patched once gives four depth-controlled modulation routes.

Reference voltages as CV offset sources. The pitch-stack patch needs a CV mixer that adds a sequencer's pitch CV to a static offset (so the sequence plays in a specific octave). Use the +6 V reference into a CV mixer along with the sequencer output, attenuate the +6 V to set the desired transposition, and the output is sequencer + offset. Negative -6 V is the same idea for downward biasing.

Mults: same use case as WR-994. Pitch CV to multiple oscillators, envelope to multiple destinations, clock to multiple modules. The WR-CP35's two banks let you keep two unrelated fan-outs visually separated.

Inputs

I1 (audio) — Attenuator 1 input. Normals to I2, I3, I4 if they are unpatched.
I2 (audio) — Attenuator 2 input. Patching here breaks the normal chain from this point on.
I3 (audio) — Attenuator 3 input. Patching here breaks the chain to O3 and O4.
I4 (audio) — Attenuator 4 input. Patching here gives O4 its own independent signal.
MA (audio) — Mult A input. Fanned out to A1, A2, A3.
MB (audio) — Mult B input. Independent from Mult A.

Outputs

O1 (audio) — Attenuator 1 output = A1 knob × source signal (normal chain).
O2 (audio) — Attenuator 2 output.
O3 (audio) — Attenuator 3 output.
O4 (audio) — Attenuator 4 output.
A1 (audio) — Mult A output 1.
A2 (audio) — Mult A output 2.
A3 (audio) — Mult A output 3.
B1 (audio) — Mult B output 1.
B2 (audio) — Mult B output 2.
B3 (audio) — Mult B output 3.
+6V (cv) — Static +6 V reference. Use as a CV offset source.
-6V (cv) — Static -6 V reference. Use as a negative CV offset source.
