OSC_MIDI_OSC

A straightforward cross-platform converter for OSC to MIDI and MIDI to OSC. Designed for zero-configuration, simply set your MIDI and OSC ports, and the software will handle the translation between MIDI and OSC seamlessly. It operates bidirectionally, performing both functions simultaneously.

You will have to structure the OSC messages in the format described below.

This tool is practical but also serves as a learning journey for me in software design. If you have any tips, suggestions, or feature requests, please don't hesitate to reach out.

• Made with: openframeworks

Downloads - if you want to just use the app

• MAC OS 10.15+ (ish) 64 bit: Available on the release tab.
• Windows 10+ 64 bit: Available on the release tab.

Note: Linux has many requirements. If you're looking for a fast and light solution for Linux, this may not be for you due to the heavy dependencies of openframeworks.

Setup - if you want to play with the code

1. Download openframeworks and set it up for your platform.
2. Navigate to openframeworksRoot/myApps/ and clone this repository.
3. Navigate to openframeworksRoot/addons/ and clone the following repositories:
   • ofxMidi
   • ofxTextInputField
   • ofxMSAInteractiveObject
4. Use the project generator for your platform to generate a project.
5. Compile for your platform.

Configuration - running the software

To configure the app, go to the data folder and edit the MIDI_OSC_SETTINGS.json file, or change the settings from the GUI! You can set the incoming and outgoing midi and OSC ports and the destination IP.

Updates

• Now includes Midi Machine control.
• Basic interactive GUI for on-the-go settings adjustments.
• Midi Show Control is now included (beta version).

Windows Users

To use this with Windows, ensure you install a virtual midi port. We recommend Loopmidi from Tobias Erichsen.

To-Do

• More detailed MSC and MTC.

OSC Format

The OSC format is consistent for both sending and receiving. Here are the detailed descriptions of the address formats:

• /cc: For controller values with two int arguments: the controller number and the value.
• /noteOn: For note on messages with two int arguments: note value and velocity.
• /noteOff: For note off messages with one int argument: note value.
• /Aftertouch: For mono aftertouch off messages with one int argument: value.
• /PolyAftertouch: For polyphonic aftertouch messages with two int arguments: pitch and value.
• /Pitchbend: For pitch bend messages with one int argument: value.
• /ProgramChange: For program change messages with one int argument: program value.

The software receives OSC messages in these formats and will automatically send the corresponding MIDI signals. Incoming MIDI signals will trigger OSC messages in the same formats.

The app wll output MMC commands from the following OSC inputs, add an int argument for the device ID and a string argument for the command

Address: "/MMCCommand" Commands are:

• stop
• play
• deferred_play
• fast_forward
• rewind
• record_strobe
• record_exit
• record_pause
• pause
• eject
• chase
• command_error_reset
• mmc_reset

The app wll output Midi Show Control commands from the following OSC inputs, add an int argument for the device ID, a string argument for the command target and another string argument for the command type, lastly add extra integer arguments for the command payload (up to 3)

Here are the command targets:

• lighting
• moving_lights
• colour_changers
