Sennheiser Vocoder VSM 201 Serviced by Studio Electronics

via this auction
"Selling a VSM 201 Classic Sennheiser vocoder. It literally looks brand new OUT OF A TIME MACHINE.. and its more than 30 years old! i believe. This piece was worth more than 20k when it came out and they only made about 30 of them.

What is special about this unit is that this unit its serial number 11. Most of the units that came out to the public where serial number 13 up, therefore this unit is one of the original, It comes with a custom case. I had it checked by David Kulka las week and its all good to go. Look at the pictures and feel free to ask me any questions.

THIS IS SOME INFO I FOUND ONLINE ABOUT IT

This is the famous vocoder used for the robot voicesin the Grandmix intro's. It has several inputs of which the voice input and the carrier input are the most important.
What it does is this. It takes a carrier sound (synth waveformor any other sound containing sufficient harmonics) and articulatesthat sound with your voice, much in the same way as your mouth articulates the sound coming from your vocal chords. It achieves this by detecting frequencies in the voice section, andopening the corresponding frequencies in the carrier section.The more frequency bands used, the better is the resulting effect.The sennheiser uses 20 frequency bands. Many more than most other vocoders, making it one of the best vocoders ever built. There are only 3 copies of this model in Europe, one probably ownedby Kraftwerk. Other people using this model are Herbie Hancock, the Cylon robots in Battlestar Gallactica, and some droids in Star Wars."

The Intellijel Mutamix


"Introducing the Intellijel Mutamix, the successor to the now discontinued Mutagen.

I went through many iterations and design changes to arrive at this final version (hence the long delay). Some of the designs involved elaborate integration of VC mixing, panning and bussing (based on the requests of many users) but the design became way too complex and convoluted. I have ended up with something that I think is unique and will allow for some creative applications (especially with regards to CV) but it is not necessarily meant to be a traditional audio mixer. I plan to make another companion product that will be purely focused on audio in the future (mono/stereo, panning, aux sends etc.).


So here is how it works:
In "NORMAL" mode all the buttons at the top act as mute on/off switches with a single click. The leds in the slider illuminate to indicate a muted channel. If I double click I will SOLO the channel and that channels led will flash on/off. I remain in SOLO state until all channels are unsoloed.

I can save the state of the muted channels into 6 possible locations (and recall them) by pressing the [SAVE] or [LOAD] buttons for about 1 second.

If I activate [KILL] all inputs and outputs are muted and all the leds flash at a rapid rate. Pressing any button will immediately exit KILL mode and return to the previous state.

[GATE] and [PULSE] allow me to select whether a corresponding channel MUTE CTRL jack toggles mute on/off (PULSE mode) or the channel is gated on/off (GATE mode) when the controlling signal is HIGH. On the mutagen this mode selection was done via jumpers on the back and the gating was inverted.

[XMODE] is a special mode. In XMODE single clicks of the buttons no longer toggle muting. Instead they instantly recall a mute state preset (the 6 possible memory locations that you would have stored using the SAVE function).
In addition to this, all of the MUTE CTRL jacks now become XMODE controls:
CLK: cycle through all the presets in a given direction (default forward) on every pulse
RESET: Start back at preset 1
DIR: toggle the direction that the presets cycle through
RANDOM: every pulse selects a preset at random.
INV: the current mute state is inverted (i.e if channels 1, 3 and 5 are muted then after a pulse, 2,4, and 6 are muted and the rest are unmuted)
MUTE-ALL: no matter what the current state, all channels are muted.

With all of these functions it becomes clear you can turn the Mutamix into an unusual sequencer!
For example: I could take a steady voltage source and feed it to a Buff Mult. I then take the 6 outputs of the buff mult and patch each one to one of the Mutamix inputs. Now the sliders will act as attenuators for the voltage and allow me to set a pitch cv level. If I then program 6 different presets where on each one only one channel is unmuted, cycling through the presets will give me a traditional pitch sequencer (although it is 6 stages).
It becomes more interesting if I replace some of the steady DC sources with audio or lfo cv and I store presets with more than one channel unmuted. Now I would get a weird sequence where different modulations are unmuted on different steps to get a very complex modulation control.

-18HP
-Skiff friendly
-6 led linear sliders for input attenuation control (leds can be easily replaced with other colors, they just slide out).
-jumpers to select pseudo log curve (instead of linear)
-All muting realised via VCAs opening/closing
-6 audio/cv inputs
-6 mute/function inputs (depends on mode)
-6 three way bus routing switches.
-3 audio/cv bus outputs
-2 linear master output level controls.
-6 control buttons + status led
-header to normal HexVCA output to the 6 inputs. (same as Mutagen).
-Expected price: $250.00

Availability. They are built! But I am just about to go on vacation and will be back in one week. When I am back Haven and I will program and test the batch and have them ready to ship out asap.

Big thanks to Haven for all the help with the feature set!"

The Science Museum Announces OraMIX Contest Winners



via The Oramics Machine on Facebook: "The moment we’ve all been waiting for. The winner of the OraMIX competition is… Chris Weeks with Telescopic Moon. Congratulations Chris!"

And the runner-ups:
"We would also like to congratulate Atomic Shadow with his second place & Obe:lus for coming third. And a special mention for Astrogarage and The Audible Smile who also received excellent reviews from our star judges."

You might recognize Automic Shadow from previous posts here on MATRIXSYNTH, including the recently announced Hollow Sun Records. Note the winning track was selected by none other than Brian Eno, DJ Spooky and The Wire.

"About [the] Competition

In the 1960s, Daphne Oram developed a ground-breaking music technique she called ‘Oramics’. With her home-built ‘Oramics Machine’, Daphne made music for TV shows and commercials, but she dreamt of broadcasting live Oramics concerts through a network of fibreoptic cables, an idea that sounded like science fiction at the time.

This ambition, so typical of that era of boundless optimism for science and technology, was paralleled in the use of satellites to broadcast Our World on 25 June 1967, the very first television production performed and broadcast live from studios across the world.

Imagine that the producer of Our World, the 1967 TV programme that first linked the world via satellites, had commissioned Daphne Oram, the pioneer of electronica, to make its soundtrack.

Now you have the chance to make that imagined track a reality, using samples from the Daphne Oram Archive, courtesy of our friends at Soundcloud; Goldsmiths,University of London; Sound and Music; Boomkat; and the Daphne Oram Trust.

You don’t have to limit yourself to 1960s style. Use the stems to make the piece in whatever genre you fancy.

Our winning track will be selected by our judges Brian Eno, DJ Spooky and The Wire."
