This class is complementary to Digital Sound Lab, with a stronger focus on interactive (non-narrative) use of sound. The principle tool to be explored is Cycling 74’s MaxMSP 5, as well as similar signal processing software (RTCMix, for example). No previous experience with MaxMSP is necessary, though a general familiarity with audio is helpful. Linking Max with other applications (Ableton Live, etc.) and extending it’s functionality through MIDI, AU and VST plugins are explored, as well as a thorough study of the parts and concepts of electronic synthesis. We also examine software synths in detail such as Propellerhead’s Reason and deconstruct some of the modules to gain an understanding of UI challenges in designing interactive, responsive instruments. The MIDI specification is covered in some detail, and class discussion key in on exploring both it’s brilliance and limitations as a music control medium. We will also examine OSC and see how it has addressed those MIDI weaknesses. The final project is an interactive piece or demonstration using one or more of the tools covered.
