Andrew Robertson is designing software that can monitor and follow the tempo of a live drummer.

Rather than the performer following exactly a pre-defined "click track" the system allows computer controlled samples and effects to be timed according to the drummers own pace. Via a process called "time-stretching" the software is then able to speed up or slow down sound samples without altering their actual pitch.

In his second Components film, Andrew puts his software to the test at Queen Mary University London with a professional drummer and explains how the technology might be used creatively in musical performance.

This film is part of a project funded by the Royal Academy of Engineering to develop the on camera communication skills of engineers across the UK.
