MixSurface

Read full description

MixSurface is a wireless control surface for the REAPER digital audio workstation. Set it up once and mix, tweak, and perform from your iPhone or iPad. REQUIRES REAPER running on your Mac or PC on the same local network, plus a small free extension. MixSurface is a remote controller, not a copy of REAPER. No REAPER handy? Tap Try Demo on the connect screen and explore the app with a simulated session, no setup required. * FADERS THAT FEEL GREAT Faders, pan, mute, solo and metering, with touch response tuned for real mixing: fast, precise and smooth under your fingers. Bank across every track, or group them into custom layers you switch in a tap. * SENDS ON FADER, INCLUDED FREE Flip the whole mixer into send mode and ride one destination across every channel, the classic console monitor-mix workflow. Pin the buses you reach for most so they are always one tap away. * BUILT-IN EQ ADAPTERS A multi-touch parametric EQ, pre-mapped to popular EQ plugins. Drag bands on the curve, pinch to set Q, and read live values straight from REAPER, with no per-plugin setup. * CUSTOM TEMPLATES Control any plugin with knobs and faders that read and write in real time, including gain-reduction metering for compressors that report it. Use the built-in templates, or map your own in seconds with listen mode: touch a control in REAPER and it binds. * GLOBAL CONTROL SURFACES Build your own pages from plugin controls, transport and one-tap REAPER actions, then make them global so they follow you into every project. * AUTOMATION AND TRACK SETUP Read and write automation from the surface, with each fader showing the automation value rather than just the trim. Name tracks, set colours, choose record inputs and set monitoring without going back to the computer. * KEEP THE VIEWS IN STEP Show only the tracks REAPER is showing, or drive REAPER's mixer from a layer you tap. Run several phones and tablets on one session and they all stay in sync. * FREE, PLUS ONE PURCHASE The mixer, track layers and Sends on Fader are free, forever. One purchase, no subscription, unlocks Channel Details, the multi-touch EQ, plugin control, custom templates and the global Control View. Family Sharing supported. Built for people who run REAPER and want a control surface that just works. Requires REAPER 7 or later on macOS or Windows, the free MixSurface extension, and a shared local network (Wi-Fi or wired). MixSurface connects over your local network only, with no account and no cloud. Not affiliated with or endorsed by Cockos Incorporated. "REAPER" is a trademark of Cockos Incorporated.
