Voltage-controlled, three-coordinate probability trigger generator

Stock immediately available from our UK supplier.
Ships from us within 1-2 working days.


Kompas from Bastl Instruments is a three-coordinate probabilistic pattern navigator. Each coordinate has a unique travelling pace and a dedicated trigger output. The amount of probability can be adjusted manually or by external voltages. Once a coordinate has been adjusted, a new pattern is generated and looped until the next change of direction.

This tool is the outcome of the environment we are in and is inspired by non-linear approach to music and life – don’t build any expectations, choose your direction and discover new paths!

Unlike common probability operation, instead of filtering a pre-determined sequence, Kompas uses probability to generate new looping patterns based on the direction you choose.
