New Make Noise Modules in Stock!


The highly anticipated revision of the Make Noise Maths module has arrived at Switched On! In addition to that we also have Make Noise Functions and the Make Noise MMG back in stock!

About the Maths...

MATHS is an analog computer designed for musical purposes. Amongst other things, it will allow you to:

  • Generate a variety of linear, logarithmic, or exponential triggered or continuous functions
  • Integrate an incoming signal
  • With no signal applied, generate a variety of linear, logarithmic, or exponential functions
  • Add, subtract and OR up to 4 signals
  • Generate analog signals from digital information (Gate / Clock)
  • Generate digital information (Gate / Clock) from analog signals
  • Delay digital (Gate / Clock) information

If the above list reads like science rather than music, here is the translation:

  • Voltage Controlled Envelope or LFO as slow as 25 minutes and as fast as 1khz
  • Apply Lag, Slew or Portamento to control voltages
  • Change the depth of modulation and modulate backwards!
  • Combine up to 4 control signals to create more complex modulations
  • Musical Events such as Ramping up or Down in Tempo, on command
  • Initiating Musical events upon sensing motion in the system
  • Musical note division and / or Flam
  • Perfect for modulating the DPO and just about anything else

Hybrid Digisound & Aries Modular Synthesizer at Switched On

Switched On recently prepared this spectacular combination of vintage Digisound and Aries modules for a customer. We were asked by our customer to resurrect two separate systems and combine the rarest and most desirable modules. The result was very pleasing, to say the least!

The patch featured in our video is based around the four wavetable-based Digisound VCDOs (Voltage Controlled Digital Oscillator), cycling through the banks of eight wavetables on each oscillator. Each VCDO has four banks of eight waveforms totaling at thirty-two possible waveforms. Occasionally you will see the bank being switched to allow a different set of eight waveforms to cycle. By multiplying the pulse signal from the Digisound Quad LFO,  all four Digisound DCOs step through their waveforms in time. One of the VCDOs is being processed through the Digisound Ring Modulator to add some metallic brilliance. Another VCDO is being processed through the Aries-paneled Blacet Frequency Divider, adding interesting harmonics. All four are being mixed and summed into the gorgeous-sounding, discrete Aries Multimode Filter. The quality of the filter is woody and organic sounding, but has the grit of a CEM based filter. The patch sends just a touch of modulation from the Digisound Quad LFO to the cutoff and resonance of the Aries filter, adding some extra animation to the sound. Since our customer did not wish to have a proper VCA in the system, we are sending the audio directly from the filter. 

We hope you enjoy the sound of this very rare and unique modular system; it was a pleasure to work on!

About the artists...


"It's as if Freddie Mercury, David Byrne, an early David Bowie, Afrika Bambaataa, and the Cure's Robert Smith had gotten together and had a baby. He (Morgan Sorne) is an enigma, chanting like an ancient tribesman, stomping like he's dancing for rain, and whirling like a helicopter, while his voice scales the ranges of the mesmerizing and hypnotic, to almost unnaturally Edith Piaf high notes." -Stephen Macmillan Moser of Austin Chronicle

Bali Yaaah

"Bali Yaaah has a droning 60's psychedelia approach to 80's synth pop. Think love child between Velvet Underground and Depeche Mode. A fusion of deep fuzzy organs, syncopated drum machines, dubbed out bass, and blazing guitars, this trio establishes an enticing wall of dark dreamy sound. Driven by band leader and organist Chris Brown (Space Invader Orchestra), complimented by guitarist Jonas Hodges (Blase Faire, X=X) and bassist Alan Uribe (Sub Oslo, Tacks, the boy disaster, and Charanga Cakewalk) together, the band evokes an alluring blend of dark synth-pop, and art rock. Rhythmically, the group's influences come from around the world. Hints of African, Asian, and Latin traditions provide the backbone to many of the group's familiar, yet foreign compositions. Their live performances have increasingly become spectacles of light and motion that meld sublimely with the band's psyched out disco doom. Their highly recommended debut EP release, Never Early Always Fate has set the stage as Bali Yaaah continues to break new ground in danceable psychedelic music. The band is currently working on a collaborative effort of remixes due out before the new year."

Listen here:


"Troller's album cover art, likely swiped from an Eighties swinger mag, sports an androgynous woman wearing only a leather vest – with an axe positioned strategically between her legs. That barbaric smuttiness defies the sonic polish positioning Troller as the most stylistically accessible project from local experimental label Holodeck. The group's debut, originally released on cassette and twice re-pressed on vinyl, includes 10 tracks that ride high on heavily processed beats, mellowed vocal wails, distorted bass guitar riffs, and dark analog discharges. Opener "Milk" pounds hard with Adam Jones' echo-maxed kick-and-snare hits, sounding like deep space hip-hop before layers of single-note phaser noises get strategically dumped atop the alien mix. Later, "Winter" demonstrates Troller's potential for beauty with twinkling keyboard pulses and Amber Star Ormand's steamy and soaring, yet lyrically indiscernible vocals. In between, several extended ambient passages splice in, but they don't test your patience as much as provide useful segues that make Troller enjoyable from initial needle drop to closer "Peace Dream," which hints at Sabbath with a doomed bassline rumbling under misty layers of analog noise. Slow, heavy, and dark, but not evil, Troller tranquilizes with unclassifiable mood music." -The Austin Chronicle

Paul F. Conly's resumé from 1970

We happened to stumble across an interesting slice of synth history and thought it was worth sharing. Below is a scan of Paul F. Conly's resume from 1970.  For those unfamiliar of Paul, he was an early electronic composer and arranger, but is more famously known for his work with the New York based psychedelic rock group,  Lothar & The Hand People.  Paul Conly was one of the first musicians to begin incorporating the Moog modular synthesizer and the theremin into contemporary forms of music. Notice under his references you see Walter Sear & Dr.  Robert Moog.  His resume clearly outlines some of his academic and cultural accomplishments. We felt this was an excellent document to help illuminate another pioneer in electronic music. If you find this interesting, check out our Flickr where we host other interesting documents, catalogs, and other synthesizer ephemera.
