Although the platform was only created as an independent organisation in 2017, activities of SIMM started already in 2015. In October 2015, the research platform SIMM staged its 1st international SIMM-posium in Ghent (Handelsbeurs) and Brussels (Kaaitheater). Leading representatives and delegates from both the practical and research fields spoke about the artistic and social-artistic work that is eligible for scientific research within the proposed research sector. The SIMM-posium served as a notification of the intention to instigate the research platform, which from 2017 on started to develop an international network of people who are engaged, either as practitioners or researchers, with music-based social-artistic work. During the start-up phase of the research platform, SIMM immediately tasked itself with accompanying the organisation of the 2nd international SIMM-posium in London (July 2017). This time, the SIMM-posium was organised by the renowned Guildhall School of Music and Drama, and in a close collaboration with Royal Holloway (University of London). The aim was to demonstrate from the very outset that – although SIMM was at its start a Ghent University and University College based initiative, and continued to be administered from Belgium out – we planned to work with and in other countries and continents. The 3rd international SIMM-posium was organized in Porto (May 2018) by CIPEM. In July 2019 SIMM succeeded to organise its first SIMM-posium outside of Europe: the 4thSIMM-posium was organized and held at the Bogota (Colombia) based Fundación Universitaria Juan N Corpas, thus making clear how important SIMM-research in the global south is to the platform. In 2020 the 5th SIMM-posium is organised on 18 and 19th December at the Centre for Fine Arts (Bozar) in Brussels. In December 2021 the 6th SIMM-posium will be held at and organised in Paris by DEMOS and the Philharmonie de Paris.
