Products of Bastl Instruments
Bastl Instruments is a synth (trouble) maker based in Brno, Czech Rep. Since 2013, we’ve been helping people develop their unique sound and build up their DIY communities centered around electronic music. We started out as a friendly group of geeks, and to this day, Bastl is a family-run operation with roots in the community. Our wild inventions cover Eurorack modules, standalone analog & digital synthesizers, studio utilities, and more, and they fit perfectly into various production setups. Inside and out, they’re designed to fight boredom and routine, since we want them to be the fuel for your creativity. Whether you’re exploring alien noise soundscapes, working on your next techno banger, or anything in-between, be ready to get your hands dirty with our classics like Kastle, microGranny or Softpop 2.
Bastl Instruments - Kompas

sold out at the moment

Probability Trigger Generator. 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. Here is a video about Kompas.Features:• global clock and reset input• 3 x 32 step pattern generators with travelling algorithms• 3 CV inputs for coordinate modulation• 3 trigger outputs• 2/5/10ms selectable trigger length (via boot settings)• 5ms default trigger length• 5V trigger outputs• 0-5V protected CV inputs• 60Hz maximum clock rate (3600 BPM)DIY-Kit-Type:THT-Kit-1. This is a Do-It-Yourself kit, not an assembled module. The kit includes all parts to build the module. Only trough-hole parts to solder. Make sure to check the build guide before you buy.

Bastl Instruments - Midilooper


Looping is one of the fastest and most intuitive ways of music-making. It's always been great for improv and invention, but why not try it with MIDI messages this time?The Bastl Midilooper is an experimental device that will help you do just that. It listens to control information about notes, dynamics, and other parameters, and it loops them in a way an audio looper would process pieces of audio. Since the MIDI loops remain in the control domain, many other processes can happen simultaneously on top of them - so you can explore timbre modulation, envelope adjustments, and way more.We designed the controls of the Midilooper to be easy to access so that the device comes in handy and enhances your music-making flow. Your fresh ideas are just a few button presses away: “[The Midilooper is] highly recommended if you’re trying to simplify your workflow and/or get away from menu-diving outside of the computer,” says a recent review in The Waveform Magazine, and we couldn’t agree more.Features:• 3 independent voices (each has MIDI channel assigned)• overdub/overwrite• transpose mode• octave transpose• quantize, velocity lock, shuffle, humanize• odd looplengths, time stretch• mute, clear, erase• one MIDI Input and two MIDI Outputs• clock input (accepts analog clock or TRS MIDI Clock)• analog reset input• metronome output• CV input connectivity (transpose, velocity, re-trigger)• pedal control (record, clear, voice selection)• USB powered• adjustable divider/multiplier for the analog clock• dimensions: 125mm x 80mm x 35 mm
