Silent Way gets 10/10 in Computer Music
It got a score of 10/10.
Some extracts:
“It works beautifully. We tried it with a Minimoog, Synthesizers.com modular, Odyssey, Roland SH-101 and even the notoriously cantankerous EMS VCS3. Silent Way was able to get each one to play nicely for at least three octaves.”
“For us, Silent Way is a no-brainer. It’s considerably cheaper than the competition and Expert Sleepers are constantly updating it. It’s a truly brilliant solution to an age old problem and one that might make you reevaluate the practicalities of owning a vintage synth.”
Silent Way v1.6.0 released
Changes in this release:
- Added support for musical scales to Silent Way Quantizer.
- Changed all the plug-in names (that appear in host UIs) from “Silent Way ...” to “SW ...”, so that more of the actual name is visible when space is limited.
- Fixed a GUI issue in Reaper on Windows.

Expert Sleepers ES-1 module announced
We’re proud to announce details of the first Expert Sleepers hardware product - the ES-1 Audio/CV Interface.
The Expert Sleepers ES-1 Audio/CV Interface is a Eurorack module designed for use with software such as Expert Sleepers Silent Way. It connects to an audio interface using standard 1/4" jack (balanced or unbalanced) or DB25 (aka DSub) connectors, and outputs CVs to your analogue synths/effects on standard 3.5mm jacks. When used with the Silent Way AC Encoder software, there is no requirement for the audio interface to be DC-coupled.
The ES-1 offers the following advantages over directly connecting an audio interface to analogue gear for CV control:
* No requirement for the interface to be DC-coupled.
* No need for special cables (e.g. TRS to TS 'floating ring' cables).
* No danger of damage to the interface - the ES-1's inputs are completely standard balanced audio inputs.
* Much greater output voltage range - up to 9x more than directly connecting a DC-coupled interface via a 'floating ring' cable.
For more details, please see the ES-1 page.

Tiptop Z8000 as oscillator
This is a pretty unconventional usage but it proves the point that as long as the Silent Way Voice Controller can send out a CV and get a waveform back, it can calibrate it, and doesn’t really care how that waveform was generated or controlled by the CV.
More details are here.

Silent Way reviewed in Sound On Sound
You can read the full review here.“If you dream of controlling your analogue synths from within your DAW software, it may be that your audio interface will let you do just that — with a little help from this plug-in suite.”
“My time with Silent Way was quite a liberating experience.”
“Voice Controller is the star of the show for me. Slick and self-contained, this has the effect of pulling a much-loved analogue synth into the heart of your DAW, with a level of control that is usually the reserve of a virtual instrument.”
“Silent Way is a genuine alternative to a MIDI-to-CV interface, and capable of a greater level of sophistication.”

Silent Way v1.5.2 released - adds AC Encoder plug-in
Silent Way AC Encoder removes the need for a DC coupled audio interface and lets you use Silent Way with almost any audio interface. The two requirements are
* your interface must have balanced outputs (almost all do).
* you need to make some special cables.
The cables are a very simple job, well within the scope of anyone with basic soldering skills.

Microtonal tuning scripts updated
Video/tutorial: Silent Way and Numerology
The tutorial is here. An excerpt follows:
This video shows how to use Expert Sleeper's Silent Way Voice Controller with Numerology. The Silent Way group of plugins allows you to use a "DC capable" audio interface as a CV control source for analog synthesizers. There are a number of advantages to this approach:
-
Easy, reliable oscillator calibration for better tuning overall.
-
When generating CV values for automation, you are no longer limited to the 127 steps of MIDI CC messages. This allows you to generate very smooth and accurate control values.
-
You do not have to worry about "saturating" a hardware MIDI interface by sending it too many messages at once.
As of version 2.2, Numerology provides integrated support for Silent Way by including direct hardware audio input and output routing in the module. This makes setup very quick, as you don't have to create separate I/O channels to route audio around, as you do in some other hosts.
Video shows Silent Way with MOTM/homebrew synth
Also of interest in this video is the audio interface, which is a Frontier Design Tango modified by Adam himself for DC-coupled operation. He’s documented the mod here.

Silent Way v1.5.1 released - adds Quantizer and CV To MIDI plug-ins
Silent Way Quantizer is a CV processing plug-in that constrains the incoming (continuous) CVs to a number of discrete values. For example, it can constrain a pitch CV to exact semitone values. This is especially useful when combined with the Step LFO plug-in in order to accurately sequence musical notes, but it can also be used with e.g. the regular LFO plug-in, or with the Voice Controller plug-in to turn portamentos into discrete glissandos.
The Quantizer plug-in is capable of loading the calibration data from the Voice Controller plug-in, in order to output accurately calibrated pitches.
Silent Way CV To MIDI translates CV signals (such as those produced by Silent Way CV Input, for example) into MIDI messages. These can in turn be used to control all sorts of software and hardware devices. Used in conjunction with, say, Silent Way LFO, the CV To MIDI plug-in provides a standalone means of generating MIDI LFOs, giving Silent Way an application to musicians who have no analogue gear at all.
Other changes in v1.5.1:
* Added ‘Random Tuning’ feature to Silent Way Voice Controller.
* Added ability to save and load calibration data to Silent Way Voice Controller.
Download now from the downloads page.

Analogue Bundle available
The Analogue Bundle combines the analogue synth controller Silent Way with two analogue-sounding delays, Augustus Loop and Little Spacey.
The bundle is priced at $90, saving $37 on the price of the plug-ins bought separately.
A summary of all the currently available bundles and pricing is here.
Silent Way sample Live sets updated
Silent Way v1.5.0 released - adds Step LFO plug-in
Silent Way Step LFO is a combination step sequencer and LFO generator. It shares many of the features of the LFO plug-in, but rather than generating waveforms based on simple sine, triangle etc. waves it generates a waveform that the user draws in the GUI. When the waveform is interpreted as a series of discrete values, rather than as a continuous wave- form, then the output is that of a traditional analogue step sequencer.
Other changes in v1.5.0:
* The Smooth control on all plug-ins is now calibrated in milliseconds, and has a much larger range.
* All Mac OS X versions now require Mac OS X 10.4.11 or higher.

Silent Way v1.4.3 released - adds CV Input plug-in
Silent Way CV Input is something of a breakthrough in audio interface-based computer/CV interaction, since it lets you get your CVs back into the computer (most other CV-generation software focusses entirely on generating CVs). Moreover this plug-in has no special requirements on the audio interface, and so is not just usable by those with DC-coupled interfaces.
This release also fixes an issue with the AU Generator versions of Silent Way DC & LFO (added in v1.4.1) when loaded as mono plug-ins.

Silent Way v1.4.0 released - adds Trigger plug-in, portamento, and swing
Changes and additions in this release:
* Added Silent Way Trigger plug-in.
* Added smoothing option on all outputs of all plug-ins.
* Added ‘swing’ feature to Silent Way LFO.
* Added portamento feature to the Voice Controller.
* Fixed a bug that would very occasionally cause the GUIs to be corrupted.
Silent Way Trigger is a simple plug-in for generating a gate or envelope in response to an incoming MIDI note. A typical application would be for triggering drum sounds, where you might have a number of different sounds mapped to different notes.

Silent Way v1.2.0 released - adds LFO plug-in
This release adds a new plug-in to the Silent Way suite - Silent Way LFO. As you might guess from the name, this plug-in is a low frequency oscillator device. It offers a variety of waveforms, tempo sync, and can be combined with the control outputs (e.g. envelopes, velocity) of the Voice Controller plug-in to achieve effects such as vibrato that fades in during each note.

Silent Way v1.1.0 released
We're happy to announce the release of Silent Way v1.1.0 (all platforms & formats).
This is primarily an update to the Voice Controller plug-in, though the DC plug-in also benefits from the OSC enhancements.
The full list of changes in this version is as follows:
• The Voice Controller AU now has an effect variant so it will work in Digital Performer.
• Added new OSC commands (registerOSCPathForParameter() and registerOSCPathForParameterNormalized()) added, primarily for compatibility with TouchOSC.
• Output configuration changed from a set of drop-down menus to a full matrix of knobs.
• Envelope scale parameters removed, since the same functionality is now offered by the output matrix.
• Added new 'velocity' output.
• Added velocity-based scaling of envelopes.
• Added Hz/V calibration mode.
• Areas of the full MIDI note range note covered during calibration are now filled with ‘wrapped around’ values from octaves that are covered.
• Added note priority modes (last/low/high) and retrigger modes (on/off).
• Added ‘panic’ button.
• Fixed some incorrect envelope triggering behaviours.
• The ‘trigger’ output is now slightly longer than before (it was previously a single audio sample).
NB the reworking of the output configuration unfortunately means that v1.1.0 of the Voice Controller is not preset-compatible with earlier versions. If you install this version and then load up a song that already uses the Voice Controller, some of the settings (notably the envelopes) will be wrong. This is something we usually go to great lengths to avoid in Expert Sleepers plug-ins, but we felt it was acceptable in this case as most workflows will involve using Silent Way to control a synth which is then recorded as audio before moving on - so to some extent storing presets is irrelevant, since you can't store the state of the synth along with it.
Get the update from the downloads page.
Silent Way and TouchOSC
This functionality will make it into the OSC implementations of other Expert Sleepers plug-ins in due course.
Silent Way v1.1 progress report
Changes so far:
* AU version has an effect variant so it will work in Digital Performer.
* New OSC command added for compatibility with TouchOSC.
* New 'velocity' output.
* Velocity-based scaling of envelopes.
* Hz/V tuning mode.
* Note priority modes (last/low/high).
I have some more stuff to add in, then this will probably be released in the next week or so.
After that, I really must add an LFO plug-in.

Silent Way VST updated to v1.0.2
These are identical except now the Voice Controller plug-in is no longer a VSTi. This makes it possible to use in Cubase, since Cubase has problems routing audio to virtual instruments.
NB if you were successfully using v1.0.1 (e.g. in Live) you may find you need to slightly reconfigure your song files to take account of this change. We apologise for the inconvenience.
The AU version is unchanged, and remains a virtual instrument.

Silent Way v1.0.0 released - new modular synth controller plug-ins
There are currently two plug-ins in the Silent Way suite - Silent Way DC and Silent Way Voice Controller. These are described in more detail below. It is anticipated that more plug-ins will be added to the suite in the future - watch the website for product announcements.
All plug-ins also feature
* full MIDI and OSC control.
* MIDI/OSC scriptability.
* sample-accurate handling of MIDI note messages.
Silent Way DC
Silent Way DC is a simple plug-in that generates constant output signals. It is intended to be used in conjunction with parameter automation (via MIDI or directly by the host application) to generate varying signals. For example, you could use it as an LFO where you draw out the LFO waveform in your host’s parameter automation GUI.
Silent Way Voice Controller
Silent Way Voice Controller is a virtual instrument plug-in designed to directly control an analogue synthesiser by generating the appropriate CV and gate signals via an appropriate audio interface.
By listening to the synthesiser’s output signal, the plug-in is able to calibrate itself to generate the appropriate pitch CV for the incoming MIDI notes.
As well as the basic pitch and gate signals, the plug-in can generate three multi-stage envelope CVs which you can feed to VCAs, VCFs etc. in your synth.
Pricing and availability
Silent Way is available immediately in Mac OS X Audio Unit format, priced at $49. Mac and Windows VST formats to follow.
