Introducing the Oscitrode

A synthesizer controlled by your skin and breath.
You extend the circuit by letting the current flow through you and the circuit extends you by turning the physical contact into sounds yielding from simple oscillations to complex and chaotic patterns.

Six analog oscillators controlled by and interacted with through twelve electrodes.
A "starve" control known from the world of circuit bending serves the mean of varying timbre and modulation in a nonlinear and chaotic way.

The electrodes are made of bare non-tinned copper and will probably change colour (and conductivity) over time adding a final time dependant layer of complexity to the circuit.

Designed to be as simple as possible to build, even for beginners.
Full kits available for dkk 150, assembled dkk 400.
Available at CPH Music Maker Space, Copenhagen N or directly from me.
Worldwide shipping (untracked), padded envelope USD 8, national shipping USD 6 (DKK 40)



Hexafonisk elektrodestyret synthesizer

Kredsløbet består af seks oscillatorer, hvis parametre - tonehøjde, amplitude og klangfarve formes ved berøring af de 12 elektroder - to for hver oscillator. Samt en “sult-knap”, der gradvist “sulter” kredsløbet for strøm og byder uforudsigelige fejlkilder og artefakter velkommen.
På mange måder lig den måde, hvorpå man kan modificere eller bøje "bende" et kredsløb, når man circuit bender - åbner et kredsløb op og stikker fingrene ind, på jagt efter spændende lyde.

Instrumentet er tilpas simpelt til, at det for nybegyndere kan være en ideel måde at lære at lodde.
For mere avancerede hackere er der rig mulighed for at viderebygge - CV-kontrol af modulation, sult eller måske et filter?

Maskinen er en hyldest til circuit bending og tungt inspireret af den famøse "Crackle Box", omend de to er opbygget på to vidt forskellige måder.

Forvent ej lyden af en Mini Moog (medmindre der tilføjes ladder-filter, cv-kontrol, klaviatur, lfo'er og vca'er), men snarere en indgang i analog lydsyntese og muligheden for selv at konstruere et instrument fra bunden af.

Oscitrode workshop, Ground Moscow

A few pictures from an Oscitrode workshop in Ground Moscow. Great place and amazing students!!

Demos of the Oscitrode

A couple of demos of the Oscitrode synthesizer.
Thanks to the builders who took the time to make demos! Much appreciated.

Oscitrode Build Video

Dmitry, a student from my workshop in Ground Moscow made this video of him building and demonstrating the Oscitrode - nice! The Oscitrode is available as a kit (20 euros) I’m happy to ship it anywhere. It is also available at the Copenhagen Music Maker Space (and now in Ground Moscow)

The Oscitrode says hi from NCCA Moscow

From Oscitrode workshop in the National Center of Contemporary Art in Moscow (NCCA). Second of March 2019

Audio demo by Alan Chamberlain

An audio demo of the Oscitrode with some fx... I'm impressed by the diversity of sounds Alan get's out of it.
