A plug-in engine developed by MOTU for use with their DAW software (Digital Performer), offering real time audio effects use and manipulation in a manner similar to the use of auxiliary sends on an outboard mixer. However, instead of using external processing, the DSP is done by the host computer and never leaves the digital domain. Supporting Macs only, MAS isn’t interchangeable with any of the other plug-in engines and will only work with MAS-enabled software. MOTU also has a third-party developer program for MAS, which as a plug-in platform has developed a niche for Mac/MOTU users.
