Cycling '74, the San Francisco-based software developer, released news of its first major upgrade of MSP for MacOS at the recent AES Convention in LA.
MSP 2.0 is a collection of signal processing objects for use with Cycling's Max, an object-orientd programming environment. Initially released in 1997, MSP extends Max's ability to create custom MIDI and media applications by adding over 100 objects that process, synthesize and delay audio in realtime.
MSP feature numerous enhancements in the area of audio I/O, including support for several file formats (from 8- to 32-bit), 512 I/O channels, and inter-application connections using Propellerheads' ReWire and Digidesign's DirectConnect. There are online tutorials etc to aid your rapid progress.
The package ships later this year, and will cost $295, though, if you are already a user, you get the upgrade for 100 bucks.
