Description
This is a used module in good working condition with little to no rack rash

Tromsø is a combination of 3 basic utility modules: VCO, Comparator and Sample & Hold. Internal normalisation allows you to instantly use it as voltage controllable analog downsampler (or sample rate reducer if you like). The sample rate is set by VCO Rate and a sort of “dry/wet” mix effect which is achieved by adjusting the Threshold when in the Track & Hold mode.

This architecture was inspired by a machine called Distortotron made in 1994 – arguably the first analog downsampler and bit distortion of its kind. That machine came from a collaboration between Norwegian musician Mental Overdrive based in Tromsø and the inventor group Psybe (Svein Berge and Henrik Sundt). It was created from a need to bring back oldschool sampler aliasing and lo-fi effects and heavily influenced the sound of album Plugged which is the landmark of the so called Tromsø sound.

Features
  • 5HP
  • triangle core VCO
  • exponential FM input with Attenuator Knob
  • tracks volt per octave over about 5 octaves when attenuator is fully open
  • switch to change range of the VCO – high= 15Hz-45kHz, low=50s – 50Hz
  • VCO output is normalised to Comparator Input thus Comparator Output creates pulse waveform for the VCO (Threshold = PWM)
  • comparator has Threshold Knob, CV Input for Threshold, Input and Output with indication LED
  • S&H section has gate input, input and output
  • switch to select mode: Sample & Hold (samples at rising gate and then holds) or Track & Hold (at high gate tracks, at low gate holds)
  • handmade locally by Bastl Instruments in Brno, Czech Republic
