The Bastl Tromsø is a voltage-controlled oscillator for Eurorack modular systems. The Tromsø is capable of creating much more complex waveforms than your typical VCO thanks to the addition of an internal comparator. The comparator interacts with the triangle-core oscillator to create complex waveforms. Tromsø's comparator can also process external sources. With all this functionality, it's hard to believe the Tromsø is only 5HP!
Tromsø will fit comfortably in the musical arsenal of even the most experimental sound explorers.
