TouchDesigner meetup 17th April – Audio visualisation

Date & Time: Saturday 17th April 5pm – 7pm UK / 6pm – 8pm Berlin

Level: Open to all levels

Join the online meetup for expert talks on audio visualisation. Meet and be inspired by the TouchDesigner community.

The meetup runs via Zoom. The main session features short presentations from TouchDesigner users. Breakout rooms are created on the spot on specific topics, and you can request a new topic at any time.

The theme for this session is Audio visualisation, hosted by Bileam Tschepe with presentations from the community.

In the breakout rooms, you can share your screen to show other participants something you’re working on, ask for help, or help someone else.

Title: Terraforming with MIDI
Bio: Bjarne Jensen is an experimental audio/visual artist from the Detroit area with an interest in creating interactive systems for spatial transformation.
Name: Jean-François Renaud
Title: Generating MIDI messages to synchronize sound and visual effect in TouchDesigner
Description : Instead of using the audio analysis strategy to affect the rendering, we are focusing on building small generative machines using the basic properties of notes (pitch, velocity), and we look at different means to manage triggering. At the end, the goal is still to merge and to make alive what you hear and what you see.

Simple Systems for Live Performance: A TouchDesigner Primer – On-demand

Level: Intermediate

Whether at a concert or in a music video, visual effects can do so much to enhance the listener/viewer’s experience and create a lasting impression. This workshop aims to demonstrate how, using TouchDesigner, one can convert MIDI and acoustic audio signal into dynamic visual performances.

Session Learning Outcomes

By the end of these sessions a successful student will be able to:


  • Design and implement generative visual effects which evolve over time

  • Map out a show control system with high-level hooks for updating state in production

  • Create simple audio +/ MIDI signal workflows


  • Persisting/loading custom presets with Python + JSON

  • Map a visualization onto any performance environment, whether physical or digital

Session Study Topics


  • How to build custom UIs with widgets in TouchDesigner

  • Encapsulating new and existing VFX patches in reusable components

  • Basic MIDI input with TouchDesigner


  • Programming advanced actions with Python in TouchDesigner

  • Making custom MIDI mappings which plug into a global control system

  • Outputting anywhere: projection mapping, NDI streaming, DMX / lighting fixtures


  • A computer and internet connection

  • A free (or higher) license of TouchDesigner

  • A text editor for programming, such as Sublime Text 3 (recommended)


  • Webcam and/or microphone

  • A text editor for programming, such as Sublime Text 3 (recommended)

  • Virtual audio routing software (e.g VB Cable on Windows, Soundflower / Loopback Audio on Mac) you can use to send audio to TouchDesigner directly from other software on your computer, such as Spotify
