The WR-994
The WR-994 is a passive multiple - a panel of jacks wired tip-to-tip with no electronics, no power, and no parameters. Patch a signal into one jack and it appears identically at every other jack on that bank. The WR-994 splits a single source into multiple destinations.
There is no DSP here. A passive multiple is electrically just a junction - all jacks on one bank are the same node. Whatever signal goes in, the same signal can be taken out simultaneously at every other jack. The WR-994 is the simplest possible solution to a fundamental modular problem: how do you send one CV or audio signal to two, three, or four destinations at once?
The WR-994 is a dual multiple - two electrically-independent banks on one panel, each wired as a 1-input / 3-output splitter. Two completely different signals can run through the same module, one per bank. Useful for keeping the visual flow of a complex patch tidy by separating two unrelated fan-outs.
The WR-994
The WR-994 has no parameters. Two inputs (A IN, B IN) and six outputs (A1, A2, A3, B1, B2, B3). Each bank is a 1-in / 3-out splitter; the three outputs of a bank carry an identical copy of that bank's input. The two banks are electrically independent and operate in parallel. There is no impedance loading - the internal bus fans out signals cleanly without loss.
In a patch
Anywhere a signal needs to reach multiple places. Common patches: a pitch CV from a sequencer fanned to multiple oscillators for unison patches; a WR-911 envelope split across a VCA, a filter cutoff, and a pitch FM destination so all three modulate together; an LFO distributed to several modules so they all breathe with the same vibrato.
In the WR-921A driver / WR-921B voice architecture, the driver outputs one composite frequency CV that has to drive multiple oscillator voices. The WR-994 is the standard tool: WR-921A FREQ OUT -> WR-994 -> three WR-921B CONTROL inputs. Each oscillator gets the same pitch CV but can be detuned slightly via its own FINE knob.
Use both banks. Bank A for the pitch CV; bank B for the envelope. Keeping the two fan-outs visually separated makes a complex patch easier to follow at a glance. For buffered fan-out (no impedance loading on the source), reach for the generic Mult instead - the WR-994 is the simpler choice for almost every case.
Inputs
- A IN (audio) — Bank A input. Replicated to A1, A2, A3.
- B IN (audio) — Bank B input. Independent from Bank A; replicated to B1, B2, B3.
Outputs
- A1 (audio) — Bank A copy 1.
- A2 (audio) — Bank A copy 2.
- A3 (audio) — Bank A copy 3.
- B1 (audio) — Bank B copy 1.
- B2 (audio) — Bank B copy 2.
- B3 (audio) — Bank B copy 3.
