Trinity is a universal musical instrument and original sounding modular groovebox. It can function as any type of digital synthesizer, sequencer, controller, arpeggiator or almost anything that can be programmed into a micro-controller. Trinity is designed to be connected and combined with other Trinities of different functions in a chain, so that you can create your own music making environment. It is ready to communicate with the outer world via MIDI and different sync and CV methods using MIDI Bastl. We are musicians passionate about exploring new fields of sonic experience – we already developed 4 different instruments for Trinity which work great together. They are sequencer, drum synthesizer, polyphonic synthesizer and monophonic FM synthesizer.…and there is many more to come!
