Routy Lite is an advanced MIDI protocol processor/router. It wires two digital devices and process messages send between them.
Connect your MIDI devices via USB OTG interface and discover completely new capabilities for your instruments.

Capabilities:
- connect together MIDI keyboard controller with MIDI sound generator and bypass messages between them
- connect MIDI piano (with internal sound generator) with other MIDI keyboard controller so you can use two keyboards at the same time
- bypass output of your digital piano to its MIDI input to split keyboard into separate sections with different sounds
- define mapping files for your instruments
- define Presets with different split points dynamically changed by simple button press
- define Sets inside Preset where you can define:
    - which keyboard parts should be used,
    - which messages will be processed,
    - what input and output channels to be used
    - how to transpose notes to desired pitch
    - how to change channel volume
    - and many more.

Minimal requirements:
- android device with USB OTG support enabled
- android Marshmallow or later (MIDI support were added starting with Marshmallow)
- USB - MIDI cable (MIDI class compliant cable), be aware that cheap MIDI cable will not work

Future plans:
- be able to switch presets by using additional USB controller (sold separately) connected with foot switch pedal
