Kompas

probability trigger generator

Buy Here

Kompas 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.

B(astl)-SIDE

Behind Kompas there is an Arduino-compatible hardware (ATMEGA328P chip) which can be re-programmed and hacked for different eurorack application.

controls:

  • 3 linear pots (B100k)
  • 3 CV inputs (0-5V protected circuit)
  • 3 trigger/gate outputs
  • 2 trigger/gate inputs

indication:

  • 2 LEDs hardwired to trigger/gate inputs
  • 3 LEDs hardwired to trigger/gate outputs
  • 3 LEDs accessible via backside header

bottom board extra pins:

  • 5 I/O digital pins (3 of them are connected to LEDs via jumper by default)
  • +5V and GND
  • RX connection pad (suitable for MIDI hack)
  • 6-pin FTDi connector

DIY KIT

Kompas is available as DIY kit which can be purchased from our noise.kitchen shop or from some of our resellers. It can also be built upon request during our DIY soldering workshops.

SOLDERING AND CODING WORKSHOP

If you are an organisation, an institute or a shop, Kompas is available as a part of our regular DIY soldering workshop or as a dedicated Arduino coding workshop upon request.

During the soldering workshop we assist participants into the soldering and assembling process of the module, the coding workshop shows how to read the code and how to hack it for different eurorack applications.

For workshop info and booking don't hesitate to get in touch with us (info[at]bastl-instruments.com)
