Silent Way SMUX
Introduction
Silent Way SMUX provides a hack to workaround the reduction in channel count over
ADAT connections when running the audio system at 88.1/96kHz.
When using an audio interface to produce your CVs that is connected via ADAT (for ex-
ample, the Expert Sleepers
), and when the audio system is
being run at a ‘double speed’ rate (typically 96kHz), the number of audio channels that
can be sent down the ADAT connection is reduced from the usual 8 down to 4. The 4
double-speed channels are multiplexed onto the 8 ADAT channels - this system is usually
referred to as ‘S/MUX’, or sample multiplexing.
The Silent Way SMUX plug-in gets around this reduction in channel count by providing a
complementary multiplexing scheme, which takes 4 channels of CVs and combines them
onto 2 channels of the double-speed audio stream. When the ADAT output is then de-
coded by a normal-speed interface (such as the ES-3 mentioned above), the channels are
demultiplexed, and so you get your 4 channels of CV back again.
In Use
The plug-in provides 4 inputs (2 stereo busses) and 2 outputs (1 stereo bus). Simply load
the plug-in on a stereo channel in your DAW and route the 4 CVs to be multiplexed into
the plug-ins inputs. Quite how you do this depends on your DAW. For example, in Able-
ton Live this can be accomplished by setting the output of a CV-generating track to point
to the plug-ins inputs. In Logic, you would use a side-chain.
The plug-in only has two controls - ‘Flip L’ and ‘Flip R’. These flip the order of multiplex-
ing of the channels onto the output stream. Unfortunately it is quite random in what order
the channels will go out - the plug-in does not have enough information from the host to
know in what order to multiplex the samples. You have to load the plug-in and flip the
channels if they’re in the wrong order. Fortunately, there are only two possibilities.
