Impressions from TMS concert 4.4.2024 Helsinki 3/3

Video from the TMS concert in Helsinki 4.4.2024.

At the Akusmata Polyphonic Festival Helsinki, TMS debut their new piece “Occurrences”. They have created a cybernetic system which registers and processes their sonic inputs coming from metal percussion and tactile resonance via piezo-microphones. The computer responds to their playing and calculates control data, not only for internal sound synthesis but also for an external modular synthesizer.The lower graph shows the input from 4 Piezos, 2 per performer. The computer analysis these signals and register timing, pitch and estimated formants, and randomly pick sequences from the data and controls with that internal and external synthesizer. The middle graph shows the computer output, on the top the pie diagrams show remaining data of the chosen sequences. Additionally the performers play custom synthesizer and process the sounds with pedals. The software is created with Pure Data for data analysis, storage and sequences, visuals are written in Python with PyGame library.
