IO-Instruments was founded by two synthesizer enthusiasts Uwe George Giegler (Berlin) and Frank Kumm (Frankfurt / Main). For many years there has been a lively exchange of new phenomena and (re) constructions in this genre. While Frank took care of the IT department of a large bank internationally, Uwe was a producer and live-act in many countries and worked for MFB for 12 years. Both regularly held public performance sessions using all types of hardware equipment.

After the formation of numerous ideas and due to peculiarities of the existing equipment, the two decided at the beginning of 2017 to found their own company: IO Instruments was born! Concepts were experimentally implemented and specified using eurorack modules, first models were created, parts were ordered, tried out, contacts made, and logo and design studies carried out. In 2018, the time had come: various work spaces were set up and equipped. A provisional office was created in Uwe’s studio on the shore of Paul-Lincke Ufer, Berlin, and the first analogue and digital circuits were defined.

Dr. Nikolai Dichev (previously ACL) from Sofia, who is now an integral part of our team, started to develop many basic synthesizer sections. Throughout 2018 a whole line was called into being, some discarded, some postponed to make an appearance later. The product line will initially be concentrated on a dozen or so eurorack modules while stand-alone devices will follow in 2020. Own poti-, switch- and fader caps designs are created and commissioned.
