Silent Way

Device Compatibility

DC-Coupled Audio Interfaces

The following interfaces have been tested with Silent Way. If you have any experience of Silent Way with other interfaces, please let us know and we'll update the chart.

Please note: most MOTU interfaces with TRS outputs are expected to work fine. The ones listed below are only the ones that have been specifically tested with Silent Way.

Note also: Silent Way CV Input has no special requirements and should work with any audio interface. The key with Silent Way CV Input is to have the right VCA - see below.

MOTU 1224 sine The headphone and main XLR outs appear to be wired with the opposite polarity than expected. This is easily resolved - see this thread.

Lexicon MPX 500 sine Not an audio interface per se but it does allow you to get two DC-coupled outputs from any spare digital connectivity your interface might have - see this thread.

AC-Coupled Audio Interfaces

Please see this page for information on using Silent Way with AC-coupled audio interfaces.

A Note On Cables

In general special cables are recommended when using a DC-coupled audio interface as a source of CVs. Most audio interfaces have balanced outputs (on TRS ('stereo') jacks or XLRs), while synth CV inputs are unbalanced (usually on TS ('mono') jacks or minijacks). If you use a regular stereo or mono jack lead, you'll be shorting out one of the balanced output signals (usually the R (ring) to the S (shield)). While this probably wouldn't be a problem for normal audio use, when outputting the sustained voltages that are useful as CVs you risk damaging the interface hardware.

The usual recommendation is to make up special cables with a TRS jack at one end and a TS at the other, connecting T->T (tip to tip) and S->S (shield to shield) while leaving the R (ring) floating i.e. unconnected.

An alternative is to wire a TRS jack to two TS jacks, connecting one T->T/S->S and the other R->T/S->S. This then gives you two copies of the output CV, one of them inverted, which is particularly useful from LFOs. Note that this cable configuration is identical to that of a regular "Y" audio insert lead.

Synths/Modules

The following synths and modules have been tested with Silent Way Voice Controller. If you have any experience of Silent Way with other devices, please let us know and we'll update the chart.
Manufacturer Module/Synth Comments Tested by
Analogue Systems RS-95 VCO The useful range of pitches is biased towards the top end of the voltage range. Setting the VCO's frequency control to +1 octave allows it to cover a better range of notes for most purposes. Also, using the "CV-in vary" input with the level set to, say, 0.5V/octave lets you cover a wider range of pitches from the limited output range of an audio interface. Expert Sleepers
Analogue Systems RS-110 Multimode Filter This filter module is capable of self-oscillation when the resonance is turned up, and works perfectly well as an oscillator in this mode. Expert Sleepers
Analogue Systems RS-380 Modulation Controller This module has an LFO with a CV frequency control. It has a Hz/volt response, and can be used as a VCO with a tracking range of about 3 octaves. Set the 'Range' switch to 'High' and the frequency control to about 12 o'clock. Expert Sleepers
