Ida Hiršenfelder: Modular synthesis simulation

A two-day workshop on modular synthesis with the VCV Rack simulator

31 August – 01 September 2022 | 17.00–21.00 @ osmo/za, Ljubljana

A two-day workshop on learning about modular synthesis with the VCV Rack simulator and a demonstration of the volumes (patches) in physical form using the Music From Outer Space (MFOS) Soundlab Ultimate and Expander DIY synthesizer. The VCV Simulator is a great tool for anyone who would like to get to grips with modular synthesis but doesn’t know where to start or has limited financial resources.

We will learn the basics of patching, and how to control three key aspects of electroacoustic sound: frequency, timbre, and intensity. A voltage control oscillator triggers the sound wave and controls its frequency. It also determines the initial tone by selecting the waveform (square, triangular, sawtooth). The module shapes the color of the sound with a voltage control filter. The amplitude of the sound and its variation over time is shaped by the voltage control amplitude. The process allows a wide range of electroacoustic musical effects.

You do not need any prior knowledge of modular synthesis to take part in the workshop, but you must have a sufficiently powerful laptop with a minimum of 2.7 GHz processing power and a minimum of 8GB of ram memory. You also need headphones to attend the workshop.


beepblip (Ida Hiršenfelder) is a sound artist and archivist. She makes immersive bleepy psychogeographical soundscapes with analogue electronics, DIY and modular synths, field recordings and computer manipulations. She is interested in bioacoustics, experimental music and sound spatialisation. She was a member of the Theremidi Orchestra (2011–2015) and is currently a member of the Jata C group for bioacoustics and sound ecologies (2018–) and the Clockwork Voltage community for modular synthesis. Her solo albums Noise for Strings, Vol. 1 (2019) and Noise for Strings, Vol. 2 (2020) were published by the Kamizdat label. She completed her Master of Sonology studies at the Royal Conservatoire in The Hague (2023).
