02.2 ArrangeUnlockNew
Live on Android · iOS in TestFlight beta
Arrange: your song on the timeline.
See the whole project the way REAPER draws it and move through it with your fingers. Jump to the chorus, check a take while it records, or fix an edit without walking back to the computer.
What you can do
- Items with waveforms, fades and colours·
- Folders open or collapsed, with their contents·
- Pinch to zoom, drag through song and tracks·
- Watch takes grow while you record·
- Hold, then drag: move items in time and across tracks, or box-select·
- Trim, fade, split, item gain, mute, delete and ripple·
- Item FX: open any item's plugins with a tap·
- Faders, arm, mute and solo in the track headers·
Select and move with your fingers
Hold a finger on an item, then drag it in time or onto another track, even a new one. Hold on empty space and drag to box-select. One undo in REAPER.
Ripple, split and loop
An edit bar with Split, Delete, Mute, Ripple, Snap and Lock, and a tap on a selected item for its menu. Drag the loop on the ruler. Locked items stay put.
Item FX
Tap the FX badge on an item to open its plugins: the same layouts, EQ and learn as track FX.
Edit items with your fingers
Drag edges to trim, corners for fades, the top half for gain. Every drag is one undo in REAPER.
Levels without leaving the arrange
Each track header gets a fader, and the selected track's full strip sits on the right.
Markers and regions on every tab
A ruler with your markers and regions on every tab, and a region list for live sets: tap to jump, long-press to play a song next. Free.
Timeline docs →02.3 Channel DetailUnlock
Channel Detail: your plugins and sends, made for touch.
Think of REAPER's FX chain and sends, rebuilt for fingers. Every plugin on the track opens as a control layout. Use the generic one for anything, or build your own for the plugins you use every day.
What you can do
- The whole FX chain: add, reorder, bypass·
- FX containers, any depth·
- A layout for every plugin, or build your own·
- Multi-touch EQ on mapped EQ plugins·
- A/B/C/D states per plugin·
- Delta solo: hear only what a plugin adds·
- Sends and receives for the track·
Parametric EQUnlock
Shape the curve with your fingers.
Drag bands, pinch to set Q, draw a new band into existence. MixSurface renders a close approximation of your plugin's own curve, so the shape under your fingers matches the plugin.

A live GR meter for any compressor that reports it, in your layouts and on Control View pages.
02.4 Control ViewUnlock
Metering: live on Android · iOS in TestFlight beta
Control View: your page for the whole project.
A blank page you fill with whatever you need from anywhere in the project: REAPER actions, plugin parameters from any track, track meters and GR meters. Pages can be global, so they follow you into every project, or belong to one project. Mapping is touch-to-learn: run the action or move the parameter in REAPER and it lands on the page.
What you can do
- Buttons for any REAPER action, toggle or momentary·
- Knobs and faders for any plugin parameter·
- Loudness metering: LUFS, true peak, PSR, spectrum, spectrogram, stereo and VU·
- Track meters and GR meters·
- Global pages or per-project pages·
- Group, colour, resize and arrange controls·
Loudness metering
Mastering and Mixing metering pages from a template: a super meter with LUFS, true peak and PSR on one dial, loudness history, spectrum, spectrogram, stereo cloud and VU. Pinch to zoom any meter.
An action sidecar
The REAPER actions you use all day on big buttons: save, render, markers, your own scripts. Turn on learn, run the action in REAPER, done.
A meter bridge
Every input or bus on one screen, next to your GR meters. Add meters from tracks and group them by section.
A FOH page
Reverb decay, delay time and mix-bus controls from different tracks on one screen, so you can change them mid-show without hunting through FX chains.
02.5 Everywhere
Works the way your rig does.
Any phone or tablet
iPhone, iPad, Android phones and tablets. Layouts rearrange for the screen you're on and for portrait or landscape.
Fine-tune per screen size
Build a layout once. If a phone needs it different, save a version for that size; the others keep theirs.
Several devices at once
Connect a few phones and tablets to one REAPER and they stay in sync: one at FOH, one on stage.
Precision when you need it
Fine mode slows every drag down. Rest a finger on a control to zoom into a narrow range around its value.
Feel docs →Your own toolbars
Reorder, hide and add to every bar. Run any REAPER action and it becomes a button. Free.
Faders that feel right
Respond the instant you touch them, slow pushes for small moves, fast throws for big ones.

05FAQ
Common questions.
How is MixSurface different from TouchOSC or Lemur?
Those hand you a blank grid and a manual. MixSurface already knows REAPER: it finds your machine, loads your tracks, and lays out your plugins. You build controls by touching parameters in REAPER, not by wiring a template by hand.
Can I run REAPER on an iPad or Android tablet?
No. REAPER runs on Mac, Windows and Linux. MixSurface is the remote: REAPER and your plugins keep running on the computer, and your iPhone, iPad or Android phone or tablet controls them over Wi-Fi or USB.
Does it work over USB, or only Wi-Fi?
Both. Connect your phone or tablet over your local network, or with a USB cable. No cloud, no account.
Which EQ plugins work with the multi-touch EQ?
A growing set of popular parametric EQs map onto the multi-touch curve. Every other plugin still opens as an auto-built control layout.
Do I need an internet connection or an account?
No. MixSurface talks to REAPER directly over your local network through a free extension. Nothing goes to the cloud, and there is no sign-up.
Can I use it for live sound or front of house?
Yes. Ride plugin parameters and faders across channels from one screen, over Wi-Fi or USB.
What do I need to run it?
REAPER 7 or newer on Mac, Windows or Linux (beta), the free MixSurface extension, and an iPhone, iPad or Android device on the same network or connected by USB.
