About This Listing

Look Mum No Computer #1114 Filter Grr Clipper VCA Eurorack Modular Synthesizer.

The #1114 Filter Grr is the Eurorack version of the unique Look Mum No Computer funky filter with built in VCA.For fans of strange-acting yet great sounding filters, the latest offering from Look Mum No Computer and Funque Mod #1114 Grr Filter is something to check out. A tweaked out, modified LM13700 low pass filter, the Grr Filter can produce some gnarly clipping and with a Shelf switch, you can adjust the characteristics of the grit. A built-in VCA makes this a great option for a compact synth voice: just add an envelope and VCO. The resonance can act delightfully strange when cranked all the way up by functioning in a stepped-sounding way adding new frequencies and notes. A unique clipping circuit imparts a unique characteristic and is achieved not by diode clipping but just by turning everything entirely too loud. Two audio inputs lets you create interesting sonic timbres and the filter sounds different depending on if you run a unipolar or bipolar VCO in it. The #1114 Grr Filter sounds unique and can easily find a place in any rack.
#1114 Filter GRR Features

  • Unique low pass filter
  • Eurorack adaptation of Look Mum No Computer's Kosmo-format module
  • Voltage controlled resonance
  • Attenuverter on frequency input
  • Built-in VCA on the output
  • Unique clipping circuit that isn’t Diode Clipping… It literally works by just turning everything up too much.
  • Shelf switch that affects the resonance and also allows asymmetric waveform clipping
  • Power consumption: 21mA (+12V), 11mA (-12V)
  • Width: 12 HP
  • Depth: 25 mm (inc. power connector)

Coming from a want for a smaller filter for some voices, this, an oscillator and an envelope generator can be put together to be a small synth voice with distortion and uniquely strange characteristics.
The filter has different behavior depending on where the oscillator is in the offset. It’s well suited for unipolar waveforms (all in + territory as in the #1222 Performance VCO) but still works great with bipolar ones.
Starting from the LM13700 data sheet lowpass filter, the circuit has been pushed, tweaked and expanded to produce some very funky sounds indeed. It’s full of character and you can even get it to step and stuff. It’s proper odd.
It's a funky filter that sounds completely different depending on whether you put unipolar or bipolar waveforms into it (you can bounce between with the Shelf switch to increase its characteristics)

From the creator: "So this is a right weirdo!!!! This was made throughout a number of patreon builders livestreams looking into the LM13700 chip as I needed to do so for a number of upcoming projects. I began with the datasheet lowpass filter and went from there until I found some very funky sounds indeed. and I have to say it is pretty cool! and it actually is quite full of character, you can even get it to step and stuff its proper odd."
