Profile: The 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 has worked for MFB for 12 years. Both regularly held public sessions using all types of hardware equipment. Due to numerous ideas and 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, logo and design studies carried out. In 2018, the time had come: Various workplaces were set up and equipped, the provisional office was created in Uwe’s studio on paul lincke shore, 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. In the course of the year 2018 a whole line was called into being, some discarded, some postponed to later. The product line will initially be concentrated on a dozen or so eurorack modules, and stand-alone devices will follow in 2020. Own poti-, switch- and fader caps designs are created and commissioned. The first prototype, the themisto VCO, saw the light of day at the end of 2018. VCA, MIXER, RING MODULATOR, NOISE and FILTER modules are in progress. In addition the physicist Riccardo Perris and software developer Sven Braun (developer of Zmors modular/app for the ipad and founder of SI GmbH) could be brought into the team, the brasilian graphic artist Jorge Kuriki supports us with the design, at the website this is Martin Sroka. Sissy Lohmeyer is doing the assembling, soldering and testing stuff and take care we all have enough coffee to work proper;) The first fairs are coming up (superbooth 2019-berlin / synthfest 2019-nantes) and a new office in the beautiful berlin old treptow neighborhood has been found. The preamplifier DIA brings the Studio Edition to life. the goal is to bring the audio quality of the 500 series into eurorack format. The second prototype, the themisto VCOs can finally go into series, the VCA Sinope and the 12x Mixer / Attenuator Sponde will be seen and heard in may. Show less
