Key Features:

• Flexible MIDI Routing: Map any input channel to any output channel on the fly.
• Message Transformation: Real-time transposition and key range filtering (perfect for keyboard splits).
• Preset Management: Create and quickly switch between entire configurations for different songs or setups.
• Advanced Filtering: Selectively allow or block messages like Pitch Bend, Control Change, and Program Change.
• Midi Panic: A dedicated "Panic" button to instantly silence stuck notes by sending Note Off to all channels.

1. Introduction and Hardware Configuration

1.1. About ROUTY

ROUTY is an advanced MIDI router designed for Android devices. The application serves as a digital patchbay and signal processor, allowing for flexible communication management between controllers, keyboard instruments, sound modules, and other MIDI gear. Whether you're building a concert rig for the stage or configuring a home studio, ROUTY gives you full control over the flow and modification of MIDI messages in real-time.

1.2. Physical Connection

To start working with the application, you must physically connect your MIDI hardware to your phone or tablet. Since most mobile devices do not have dedicated MIDI ports, the connection is made via the USB port using appropriate accessories.

• MIDI Interface: For communication with instruments equipped with traditional 5-pin DIN ports, use a USB-MIDI interface, such as the Roland UM-ONE.
• USB OTG (On-The-Go) Adapter: A special cable or adapter that allows an Android device to act as a "host." This enables the phone or tablet to power the connected interface and receive and send MIDI data.

Step-by-step connection instructions:

1. Connect the USB OTG adapter to the charging port (USB-C or Micro-USB) on your mobile device.
2. Plug the USB connector of the MIDI interface (or a USB MIDI controller directly) into the OTG adapter.
3. Connect the interface plugs to the instrument: the MIDI IN tip to the MIDI OUT port on the instrument (and vice versa – the MIDI OUT plug to the MIDI IN port).

1.3. Hardware Requirements

• Support for USB OTG Standard: This is a necessary condition for the application to function correctly. Without hardware and software support for OTG, the phone will not detect the MIDI interface. In some models, the "OTG Connection" function must first be manually enabled in Android system settings.
• Power Delivery: Power for the MIDI interface or controller is drawn directly from the phone's battery. For large setups, consider an active OTG adapter with an additional power socket for simultaneous charging.

2. User Interface (Home Screen)

2.1. Control Center

The main screen of ROUTY is designed for maximum readability and ergonomics. It serves as a central control panel, from which you have immediate access to all MIDI signal flow configurations. The interface focuses on quick navigation and precise presentation of the active routing state.

2.2. Preset List

The heart of the ROUTY interface is the dynamic preset list. Each preset is an independent set of rules (sets) that determines how MIDI messages should be processed and transmitted.

• List Management: Add, delete, or copy configurations at any time.
• Reordering: Arrange presets in the order you will play them during a concert for instant switching between tracks.

2.3. Optimization for Mobile Screens

Each expanded preset can be collapsed into a compact bar, displaying only basic information. This allows you to fit dozens of items on one screen without constant scrolling, increasing clarity on stage.

2.4. Personalization

Each item on the list can have its own name, such as "01_Cyber_Track" or "Split: Bass / Lead Synth", ensuring you immediately see which preset to activate.

2.5. Visual Guide

3. Routing Architecture: Presets, Sets, and Zones

3.1. Data Hierarchy

[ PROJECT ]
   │
   ├── [ PRESET 1 ] (e.g., "Cyber Track")
   │      ├── [ SET 1 ] (Bass synth rule)
   │      ├── [ SET 2 ] (Digital piano rule)
   │      └── [ SET 3 ] (String section rule)
   │
   └── [ PRESET 2 ] ...
            

• Project: The main file containing your entire configuration.
• Preset: A container for a specific song or part of a performance.
• Set (Rule): A single, independent MIDI signal path within a preset.

3.2. Set (Rule) Parameters

• MIDI Input/Output: Define source and destination channels.
• Transpose: Shift notes in semitones.
• Level: Set volume (CC7) for the rule.
• Bank/Program Change: Automatically trigger sounds on your instruments.

3.3. Key Range and Zones

Define Low Note and High Note to create keyboard splits. For example, assign Bass to the lower octaves and Lead to the upper ones.

3.4. Layering

Define multiple sets sharing the same Key Range to send signals to different targets simultaneously (e.g., Piano + Strings + Bells).

3.5. MIDI Channel Conflicts

It is very important that each set (rule) has a different MIDI output channel defined. When you select a new preset using the "Next Preset" button, Bank Change messages are sent to the output device to switch the selected sounds. If two sets in a given preset share the same MIDI output channel, the sound settings will be determined by the last rule with that output channel in the preset.

4. Main Menu Structure

4.1. Project Section

Manage your configuration files: create new projects, save changes, and load existing setups from your device's memory.

4.2. Routing Section

• Start Routing: Enables MIDI processing between input and output devices connected to the application.
• Play Test: Sends a sequence of notes to the output device to verify that the routing is correctly configured and working.
• Play Panic: Sends Note Off MIDI messages to every MIDI channel for every note, ensuring no "stuck" or orphaned notes continue to play.

4.3. Application Section

• Settings: A configuration window where global application behavior can be modified.
• Privacy Settings: Allows users to manage consent and options related to advertisement display.
• Open Source Licenses: Provides a comprehensive list of all open-source libraries used within the program and displays their respective licenses.
• About: Displays the current application version and provides direct links to the official website and the End User License Agreement (EULA).
