Ida Hiršenfelder: Voltages Chirping Vehemently (VCV)

Online monthly meetings on modular synthesis with the VCV Rack simulator.

08 January – 03 December 2023 | 8pm @ online

We are starting a new season of Modul@rnice on 8th January!

Modul@rnice will host monthly online Voltages Control (VCV) meetings for modular synthesis with the VCV Rack simulator, which contains over 1,800 free-to-access simulations of Eurorack modules. All the meetings will be held online. They will be led by Ida Hiršenfelder (beepblip). The teaching is planned as an open format for peer-to-peer learning, where participants can suggest topics and influence the course of the meeting.

Each session will be dedicated to the development of one music patch, which will interweave two thematic aspects: Musical or genre (rhythmic, harmonic, polyphonic, polyrhythmic, textures, granulation, pad, generative music) and technical or methodological (clocks and sequencers, granular synthesis, phase reversal, gated filter, connection to acoustic instruments and external MIDI controllers, sound/ring modulation). One of the goals of the meetings is to jointly search for Slovenian equivalents for modular synthesis terms that are not currently established.

How to apply

The meetings will be held via Zoom and will be in Slovenian. They are designed so that complete beginners as well as those who are already familiar with the VCV Rack tool can attend them at any time during the year. The only requirement is to watch the introductory video in which the artist explains the basics and prepares you to follow the meeting more easily.
