this is an emf detector – 2 inductors for stereo – 1 stereo – 2 mono outputs – that’s it…there are lots of unusual sounds to find inside your apartment/house – just walk over to the fridge, or “scan” the surface of your computer monitor while clicking away – just amazing…
this is lärm no. 4 – a nand gate based quad oscillator
pitch control is achieved via pots or photo resistors (switchable for each channel) – the oscillators modulate each other but their signals also have separate outputs – 6 rotary switches alter filter settings and can extremely change the sound and interaction of the oscillators – also, the main pitch can be adjusted via external CV – sputtering noise, drones and basic rhythmic patterns are just a few things this little beast can provide…
This is lärm no. 3 – a quad distortion audio processor / filter / spatial distributer…
send audio into its 4 channels…distort the signal via a combination of transistor fuzz, diodes and op amps…and either use the photo resistors to distribute the 4 signals spatially or the mini joystick to send 1 or a combination of signals to 4 different speakers…a multitude of distortion types can be selected via switches and driven into insanity via pots…the photo resistors act like simple low pass filters…also, the unit comes with stereo outs and 4 pan pots to place the 4 signals within the stereo field…
this is the werkstatt extension – a 2nd oscillator, 2nd LFO, 4 light sensors + a gate in
the light sensors are switchable and give control over pitch / LFO / filter and volume…most of the werkstatt on board inputs / outputs are routed to the extension + 2nd LFO out / VCO square and saw out – mixing it all up and using light to control parameters creates a whole new instrument…the exciting soundscapes of the already excellent sounding werkstatt can be delved into further …the extension also makes interfacing other gear possible…
this is lärm – a quad noise maker / weird filter / panner
lärm is based on 4 circuit bent op-amps and 4 LFOs…it can be used in a quad speaker environment or just via a stereo mix of its 4 quadrants / channels…both control and playing surface are separated this way, though the latter allows overlapping of its areas…a plethora of connections can be made via touch…some will create oscillations with various pitches, or some can mute the signal and change its timbre while the LFOs can interact with all of those…buzzing, hum, crackling from the LFO, arhythmic patterns and much more…the timbre of the internal oscillations is at times shrill and harsh…a very direct and intense sound that becomes especially interesting when blended with other sound sources via the 4 inputs…there are also a bunch of stable and unstable CV outputs from the LFOs…even patch cables inserted into one or more of the these outputs can be used to alter sound by touching the playing surface with it…its endless…
this is lärm no. 1 – a noise maker / low pass gate / 6 ch-mixer…
here the fine print: there are 5 chip oscillators on the left which can be manipulated manually or with light…another 4 in the center which can interact with each other…an “opened” preamp circuit with 6 touch pads (noizzzzze!)…and the mixer / low pass filter on the right…2 channel output on the back…that’s it!
this is lärm no. 2 – a noise box / preamp / matrix mixer hybrid…
here is the set-up: in the center sit 2 preamps with insane gain stages …below that are 2 frequency dividers which can be directly connected to each of the preamps…on the right is a passive ring modulator whose circuit has been “opened” and can be altered by touch…intense and very unpredictable outbursts of noise are the “results”…everything is (as usual) interconnectable, so even plugging in a contact mic, your electric ukulele, or whatever else you have laying around can make some incredible noise!
