> The IRCAM merged it with their Cube-based synthesis and processing system. Eventually that became Max/MSP, a commercial product with both MIDI and audio generation and processing.

Miller Puckette, the original author of Max, left IRCAM and went on to develop Pure Data (Pd) as an open source alternative. Pd introduced realtime audio processing. Max integrated Pd's DSP code and became Max/MSP. MSP stands for 'multi signal processing' or 'Miller S. Puckette'. (Miller himself named Max after computer music pioneer Max Mathews.)
