The RxMx is a Vactrol-based 6-Input, 3-Output, macro-Low Pass Gate and Signal Crossfader. The concept is
based on Grant Richter’s circuit idea for applying “cadavre exquis” (aka exquisite corpse, a technique of serial
blind composition) to modular synthesis. When modulating the RxMx with a Wogglebug, one will achieve modular
“cadavre exquis.” When patch programming the RxMx with a sequencer such as the Pressure Points/ BRAINS or
René, modular “mélanger automatique” (automatic re-mixing) can be achieved. Because it uses Low Pass Gates
for level control and crossfading, the RxMx excels at smooth dynamic blending and percussive animation of
related or unrelated signals.
The LEVEL and Strike parameters are similar to those of the Make Noise Optomix. If you’re unfamiliar,
LEVELcontrols the amplitude and frequency content simultaneously. Strike can be used to trigger Channel(s) of
the LPG (Low Pass Gate) circuit by “plucking” or “pinging” the vactrol, briefly opening the LPG circuit to 100%,
thus allowing it to impart its magically-slow response time upon the amplitude of the signal being processed.
The Channel parameter selects which of the 6 Low Pass Gate circuits is driven by the LEVEL and Strike
parameters and the RADIATE parameter turns on channels adjacent to the one chosen by the CHANNEL
parameter. At maximum RADIATE settings, it is possible to have all six channels become active simultaneously.
Therefore, RADIATE allows for Voltage Control of the complexity of the mix, ranging from 1 to 6 active sound
sources, with CHANNEL selecting the focal point of the mix.
There is an Expansion Header on the back of the module, allowing for un-patched connection to 6 Waveforms
from the DPO (2 of which are not accessible on DPO itself), resulting in gorgeous, waveform scanning. When
normalled to a DPO, the Waveform Channel distribution is as follows:
Ch 1: VCO A Saw
Ch 2: VCO A Triangle
Ch 3: VCO A Sine
Ch 4: VCO B Triangle
Ch 5: VCO B Final Output
Ch 6: VCO B Spike
Connecting the RxMx Expansion cable to the DPO does not change any behaviors on the DPO.
Any internal connection from DPO to RxMx may be overridden by patching into one of the RxMx
Channel INputs.
Alternatively, you could choose to use the un-patched connection to the 6 bands of the FXDf Fixed Filter module
via the Expansion Header, allowing for Voltage-Controlled, percussive spectral animation of a single sound
source, such as a loop from the Phonogene. For more information, consult the FXDf Manual.
Connecting the RxMx Expansion cable to the FXDf does not change any behaviors on the FXDf.
Any internal connection from FXDf to RxMx may be overridden by patching into one of the RxMx
Channel INputs.
Using the 3 Outputs, the RxMx can have a variety of output configurations. Choose either (1) Six-Channel
Output, (3) two-Channel Outputs, or (1) Four-Channel and (2) Two-Channel Outputs for parallel processing
patches with up to 3 independent signal processing paths. The Aux A and Aux C inputs are also available for
adding two more signals to the mix such as the SUM Outs from the Optomix and modDemix, allowing for larger
more complex mixes to be patched.
