Build a MIDI 2.0 program using the Apple UMP API – Workshop 2 / December 6th

Date & Time: Monday 6th December 2021 6pm UK / 7pm Berlin / 10am LA / 1pm NYC

This workshop builds on the first UMP Workshop, and focuses on C++ development using the new Apple UMP API. Automatic 20% discount will be applied at checkout to this workshop if purchased at the same time as the first workshop.


Difficulty level: Advanced

  • Inspect the new Apple UMP API
  • What can be done with the API, where are limitations?
  • Build a simple UMP program in C++


This workshop builds on Workshop 1, and will provide developers with knowledge and code for implementing MIDI 2.0 Universal MIDI Packet (UMP) development using the Apple UMP API in C++. The Apple UMP API will be presented and explained. Then, the participants will co-develop a simple implementation in C++ using the Apple UMP API. For that, a stub workspace will be provided. Exercises will let the participants practice the newly learned concepts. Xcode on MacOS 11 required for building the workshop code.

Learning outcomes

At the end of the workshop the participants will:

  • Be able to build MIDI 2.0 products using UMP using the Apple UMP API

Study Topics

  • Looking at the Apple UMP API
  • Extending the code from Workshop 1 with Apple i/o
  • Presenting fragments of the code in the stub workspace
  • Testing and interoperability with MIDI 1.0

Level of experience required

  • Attendees who joined workshop 1 <add link>
  • Some experience with C++ coding required
  • Attendees should be familiar with MIDI 1.0; they should have experience building and debugging applications using Xcode (macOS)

Any technical requirements for participants 

  • A computer and internet connection
  • A webcam and mic
  • A Zoom account
  • for development: Xcode on MacOS 11
