The year's seminars covered the following topics:
- Transformations of instrumental sound using a real-time digital processor.
- Extension of the notion of arpeggio, using regular delays and transformations such as frequency shifting and ring modulation.
- Demultiplication of instrumental rhythms using rhythmic sequences associated with delays.
- Modification of instrumental sounds by synthesized sounds or other instrumental sounds.
- Frequency detection: difficulties in detecting an instrumental frequency; different applications for triggering either a modification process or a synthesized score.
- Spatial distribution: dependent or not on other criteria, such as dynamics.
- Study of the programs on the 4X machine that enable these operations in real time.
