REAPER Feature Highlights
  • Unlimited creativity with no track limit, free routing for sample-accurate MIDI and audio alike, sidechain control of any plugin
  • Incredibly flexible and powerful routing - functions as an entire virtual studio with patchbays, enabling all sorts of effects not possible anywhere else
  • Fast installation and execution - starts up in seconds, always ready to record
  • Streamlined, tool-less work flow with context menus and item handles for fades, volume, per-item effects, etc
  • Integrated network FX processing - use spare machines for additional processing power
  • Supports mixing sample rates and media formats on the fly - WAV, AIFF, OGG, FLAC, ACID, APE, WavPack, MP3*, and more
  • Intuitive editing features - auto-crossfades, takes and lanes, ripple editing, arbitrary item grouping and locking
  • Unlimited sound processing - tons of included FX, support for thousands of third party virtual instruments, sample players, audio and MIDI processing plug-ins (VST, VSTi, DX, DXi, JS)
  • Design your own graphical interface and create your own custom action lists for total customizability

REAPER Feature Guide

Fast and powerful editing
  • Drag and drop files to instantly import them into a project, arrange, and render out to a file
  • Mix any combination of media, file type, sample rate, bit depth on each track
  • Easily move, split, glue, resize, trim, loop, timestretch, pitch shift, fade, crossfade, snap items
  • Intuitive zoom, scroll, scrub, jog, tab to audio transient, midi navigation
  • Separate audio or midi into freely arrangeable takes and lanes for easy comping
  • Normalize, quantize, and more complex per-item manipulation
  • Configurable and editable automatic crossfading of overlapping items
  • Powerful folder system allows group editing, routing, bussing all in one step
  • Easily group any number of items across any number of tracks
  • Ripple editing - moving and deleting items can optionally affect later items
  • Unlimited tempo, time signature, and playback speed changes per project
  • Define and easily copy/move regions, to quickly try out alternate arrangements
  • Record and edit automation envelopes for volume, pan, mute, plug-in parameters, playback speed, pitch
  • Lock items, envelopes, loop selection, and other elements independently
Unlimited and creative routing capabilities
  • Any track can function as a track, bus, or bus folder - any signal can be sent anywhere else
  • Unlimited parallel sends to other tracks or hardware outputs
  • Sends can be fully configured: audio, MIDI, before or after FX and track controls, volume/pan/phase
  • Tracks can have as many as 64 individually routable channels for easy support of multi-out virtual instruments, parallel FX processing, sidechaining, and submixes
  • Visual routing matrix to easily view and change signal flow for the whole project and every plug-in
  • Any audio signal can be converted into parameter modulation for sidechain control of any plug-in, even plug-ins that don't support sidechaining
Powerful recording and rendering options
  • Direct multi-track recording and rendering to all supported formats, including WAV, AIFF, OGG, FLAC, ACID, APE, WavPack, MP3*, and more
  • 64-bit audio signal path throughout, for maximum resolution and clipping overhead
  • Any track can record any audio or MIDI input signal, or that track's processed audio or MIDI output
  • Punch and auto-punch recording in and out, loop and overdub MIDI, and change track recording settings on the fly
  • Easily split, glue, explode, and collapse recorded items and takes
  • Optionally bounce mixed output live to disk
  • Automatic gapless file switching to avoid 2GB/4GB filesystem limits
  • Import and export cues and loop markers
  • Very high quality dither and noise shaping options for final audio renders
Extensive MIDI support
  • MIDI items can be mixed and arranged with audio on any track
  • Piano roll, drum map, or event list MIDI editor with multiple continuous-controller lanes
  • MIDI channels are as freely routable as audio, with unlimited parallel sends
  • Multi-track recording/monitoring of any MIDI hardware input, and any track can send to any MIDI hardware output
  • Support for MIDI virtual instruments (synthesizers and sampler players) and MIDI filter/processing plug-ins
  • Record MIDI input in loop, punch, and overdub mode, or record processed MIDI output from any track
  • MIDI ReWire support
Totally customizable
  • All graphical elements are themeable - create your own user interface colors and images or choose from hundreds of user-created themes
  • Configure and dock utility windows right where you want them, save and restore screensets
  • Create custom action lists and assign keyboard or MIDI controller shortcuts to do complex tasks with ease
  • Track and FX chain templates allow you to easily save and reuse work
  • Define aliases and organize hardware I/O and plug-ins
  • Fully searchable pages of user preference settings allow you to set default behavior exactly the way you want
  • Use the included JS effect scripting engine to design your own audio and MIDI plug-ins, including graphical interfaces
  • Public API/SDK allows seamless integration of third-party extensions
