Already as a kid, MuTools founder Jo Langie was passionate about music and technology. He built his own hardware synth when he was 15 years old (and used it on-stage), and later on started R&Ding music software. At the same time he was very active as a musician, mainly in the electronic music styles.

Step by step I.M.S. (Intuitive MIDI System) grew into one of the first generation software sequencers available on the Atari computer, in concurrence with other apps like Steinberg's Pro24 and Cubase, and C-Lab's Creator and Notator, and others. I.M.S. was intensively used by a closed group of musicians and was not commercially available at that time.

Later on tech company MeepMeep participated in the commercialization of I.M.S. resulting in the new product MBoom. Mboom was a unique MIDI sequencer that combined pattern-based and linear song arranging with an integrated audio sampler. MBoom was available for both MacOS and Windows computers.

On the MBoom foundations, Jo Langie developed Muzys, a next generation music sequencer which was much appreciated by many musicians around the world. Muzys not only allowed for recording, playing and editing of MIDI but also featured integrated high-quality sound and effect modules like the MuZynth and the RevOrb.

Muzys' strength was also noticed by Computer Music magazine and they licensed a customized version of Muzys, Computer Muzys, as the main part of their music studio that was bundled with their magazines.

Following the success of Muzys, M-Audio (now Avid) and main developer Jo Langie cooperated many years on several high-quality music products. Due to non-disclosure agreements, no more details can be listed here.

Since the world crisis caused deep reorganizations, Jo Langie founded MuTools and developed MuLab (initial name 'Luna'), state of the art music studio software for OSX and Windows. MuLab is both a flexible music composer and a completely modular audio engine which results in vast creative and productional possibilities.

In 2009, the Svendborg Gymnasium, one of the largest Upper Secondary Schools in Denmark with 1000 students and 100 teachers, chose to use MuLab in its courses.

2010: Tunited, a new community website for independent music dreamt up by Ultravox legend Midge Ure, selected MuLab as their primary music application to launch new musicians.

2009-2011: Formula One Management Ltd contracted MuTools to R&D their new real-time audio processing software used during the broadcasting of Team Radio.

2012: MuLab 4: The next generation of this top-quality sound and music production system for Mac OSX and Windows.

2012: The Blessed Edward Oldcorne Catholic College chose to use MuLab in its courses.
