Attention: This app is not a standalone product. It works in combination with the REAPER plug-in ReaLearn only. If you don't know what this is, please don't install this app. Thank you! This is an addition to ReaLearn which allows you to project a schematic representation of your currently active controller to your mobile device: 1. Use this app to scan the QR code displayed when you press the "Projection" button in ReaLearn plug-in. 2. Put this device close to your controller in order to see immediately which control element is mapped to which parameter. For more information, please visit the ReaLearn project website https://github.com/helgoboss/realearn.
