OrangeAid is a MIDI controller app for Reason and Reason Essentials, giving you seamless integration with all your favorite Rack devices.

Whether you’re tweaking away in search of that new synth lead, making beats, recording or performing OrangeAid is ready to help.



Create Layouts

Create your own layouts to control your Rack devices, song files and play instruments the way you want, all from within the app.

You can use multiple layouts per device too. For example, you could create several layouts for different sections of SubTractor to use while designing patches, and a separate layout just for performance controls.

Choose How to Control…

Adding and editing controls is all done live in the app. A single tap switches in and out of the editor, so you can set up your controls and try them out straight away.

…and What to Control

Parameter mapping is a breeze with OrangeAid. Just browse the built-in lists and tap to map!

There’s Undo & Redo too, so feel free to experiment with different combinations of controls and mappings.

Control Your Rack


OrangeAid can follow the Master Keyboard input in Reason, so when you change tracks in the Sequencer, your rack layouts automatically change to match the new device.

You can also use Reason’s surface locking to stay focused on a specific instrument or effect.

Control Your Song


Use layouts for your Reason song files to control tempo, click, loop settings, create new overdubs & alternative takes and so on.

There are handy Transport controls too.

Keyboard & Pads


Use the MIDI keyboard and Drum Pads to play your Instruments.

As well as standard MIDI note mappings, you can assign pads to device-specific note mappings for supported devices, such as Redrum and Dr. Octo Rex.

Transport, Track & Patch

These controls are always available, no matter which type of layout you’re using.

OrangeAid + Reason


OrangeAid is designed to take full advantage of Propellerhead Software’s Remote technology for complete, two-way communication with Reason.

You can set OrangeAid to be Reason’s Master Keyboard, or use it alongside your existing MIDI keyboard and control surfaces.

Connect to Reason via Wi-Fi, MIDI over Bluetooth LE, or use a wired connection via a class-compliant MIDI interface for iOS.
