It is currently available for Microsoft Windows (98/Me/2000/XP/Vista/7), Wine and Mac OS X (10.4/10.5). Version 3 of REAPER was released on May 22, 2009.
REAPER supports plug-in APIs such as VST, VSTi, DX, DXi and also integrates the company’s own plug-in and FX scripting API, Jesusonic. REAPER can furthermore function both as a ReWire slave and host. It ships with a host of native FX plug-ins. Another feature is its ReaMote application that allows the user to use the CPU power of a second PC to process plug-ins over a local area network.
REAPER is an alternative to popular digital audio workstation software such as Pro Tools, Cubase, Logic Pro, Cakewalk Sonar, Sony Vegas, SAW Studio, ACID Pro and FL Studio.
