The Bastl Tromsø is a VCO comparator. 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. The sample rate is set by it's VCO Rate and a “dry/wet” mix effect which is achieved by adjusting the Threshold when in the Track & Hold mode. that combines three essential utility functions in one module: VCO, comparator and sample & hold. Primarily, the module takes care of analog, through CV controllable down-sampling (reducing the sample rate). The circuit design was based on a machine called Distortotron in 1994, when the first analog down sampler and bit-distorter were built. It was designed to aliasing vintage samplers and replicate in order to realize violent LO-FI effects which character is responsible for the so-called Tromsø Sound.
