Getting started with Interactive Machine Learning for openFrameworks – On-demand

Level: Intermediate – C++ required

Using openFrameworks, ofxRapidLib and ofxMaximilian, participants will learn how to integrate machine learning into generative applications. You will learn about the interactive machine learning workflow and how to implement classification, regression and gestural recognition algorithms.

You will  explore a static classification approach that employs the k-Nearest Neighbour (KNN) algorithm to categorise data into discrete classes. This will be followed by an exploration of static regression problems that will use multilayer perceptron neural networks to perform feed-forward, non-linear regression on a continuous data source. You will also explore an approach to temporal classification using dynamic time warping which allows you to analyse and process gestural input

This knowledge will allow you to build your own complex interactive artworks.

By the end of this series the participant will be able to:


  • Set up an openFrameworks project for machine learning

  • Describe the interactive machine learning workflow

  • Identify the appropriate contexts in which to implement different algorithms

  • Build interactive applications based on classification, regression and gestural recognition algorithms

  • Collect data and train a neural network

  • Use the neural network output to control audio parameters

  • Design gestures as control data

  • Use classification of gestures to control audio output

  • Refine gestural input to attain desired output

  • Integrate visuals for multimodal output

  • Build mapping layers

  • Use models in parallel and series

An introduction to Flora for monome norns – On-demand

Level: Some experience of norns required

Flora is an L-systems sequencer and bandpass-filtered sawtooth engine for monome norns. In this workshop you will learn how L-system algorithms are used to produce musical sequences while exploring the script’s UI and features.

Flora on Vimeo

By the end of the first workshop, you will be able to:

  • Navigate the Flora UI and parameters menus to build and perform your own compositions

  • Create dynamically shaped, multinodal envelopes to modulate Flora’s bandpass-filtered sawtooth engine

  • Build generative polyrhythms and delays into your compositions

  • Use crow and/or midi-enabled controllers and synthesizers to play Flora

Session study topics:

  • Sequencing with L-system algorithms

  • Physical modeling synthesis with bandpass filters

  • Generate multi-nodal envelope

  • Norns integration with midi and/or crow



  • A computer and internet connection

  • A norns device with Flora installed

  • Optional: A midi-enabled controller and/or synthesizer

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.

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.

Understanding Indian rhythm through simple algorithms – On demand

Level: All Max users

South Indian Carnatic music is home to a huge array of fascinating rhythms, composed from algorithms. Rooted in maths and aesthetics, Carnatic music has many facets that can be applied to computer music. In this workshop you will be given an introduction to this tradition, and provided with the opportunity to observe, create, and hack various patches that demonstrate some of these ideas.

Session Learning Outcomes

By the end of this session a successful student will be able to:

  • Be capable of reciting a simple rhythmic konnakol phrase

  • Be capable of conceiving simple rhythmic algorithms

  • Be capable of translating these concepts into simple Max patches

  • Understand South Indian rhythmic concepts & terminology such as Tala, Jhati, and Nadai

Session Study Topics

  • Learning a konnakol phrase
