MIDI 2.0 introduction

Welcome to the future with MIDI 2.0

Music is a universal language that has the power to move hearts and captivate minds. For decades, the MIDI (Musical Instrument Digital Interface) protocol has played a significant role in connecting electronic musical instruments, enabling musicians to create and produce music in a digital realm.

But now, a new era has dawned upon us with the arrival of MIDI 2.0, promising a whole new level of musical expression and creativity.

What is MIDI 2.0?

MIDI 2.0 is the next generation of the MIDI protocol, which has been widely used by musicians, producers, and composers since its inception in the early 1980s.

While MIDI 1.0 allowed instruments to communicate basic note and control messages, MIDI 2.0 expands upon these capabilities, offering enhanced features and opening up a world of possibilities for musical exploration.

Key Differences from MIDI 1.0:

  • Bidirectional Communication: One of the most significant advancements of MIDI 2.0 is its bidirectional communication capability. In MIDI 1.0, communication was unidirectional, meaning that information flowed in one direction, typically from the controller to the instrument. With MIDI 2.0, instruments and controllers can now exchange data both ways, enabling real-time feedback and interaction between devices.

  • Increased Resolution and Expressiveness: MIDI 2.0 significantly improves upon the standard 128 steps-resolution of MIDI 1.0. With MIDI 2.0, musicians can enjoy finer control over parameters such as velocity, pitch, and timing, allowing for more nuanced and expressive performances. This increased resolution translates into more realistic and dynamic instrument performances.

  • Profiles and Property Exchange: MIDI 2.0 introduces the concept of profiles, which allows devices to communicate their capabilities and requirements to one another. This means that when you connect a MIDI 2.0 instrument to a compatible device, they can automatically configure themselves and optimize the communication settings, simplifying the setup process.

Backwards compatibility

Backwards compatibility between MIDI 1.0 and MIDI 2.0 is of utmost importance as it ensures a smooth transition and integration between the two protocols, preserving the investments and existing setups of musicians, producers, and the entire music industry.

By maintaining compatibility, MIDI 1.0 devices can continue to be used alongside the newer MIDI 2.0 devices, allowing for a gradual adoption of the new protocol without rendering older equipment obsolete.

This ensures that musicians can embrace the advancements of MIDI 2.0 while still leveraging their trusted MIDI 1.0 devices, fostering a seamless and inclusive environment for musical creativity and production.

Bluetooth MIDI and MIDI 2.0

Bluetooth MIDI communicates bidirectionally by default and potentially plays an important role in ensuring backward compatibility between MIDI 1.0 and MIDI 2.0.

By utilizing Bluetooth technology, MIDI devices equipped with Bluetooth MIDI capabilities can seamlessly communicate and exchange information between the older MIDI 1.0 devices and the newer MIDI 2.0 devices.

This bridging capability allows musicians and producers to connect their existing MIDI 1.0 instruments with MIDI 2.0 enabled devices, enabling a unified ecosystem where both protocols can coexist harmoniously.

Bluetooth MIDI eliminates the need for complex adapter setups or dedicated MIDI interfaces, simplifying the integration process and ensuring a smooth transition to the advanced features of MIDI 2.0 while still leveraging the vast MIDI 1.0 ecosystem.

That is why, the MIDI Association offered its members the ability to add WIDI Core to the first prototyping tool for MIDI 2.0, AmeNote’s ProtoZOA.


The arrival of MIDI 2.0 marks a new chapter in the world of music production and performance. With its bidirectional communication, increased resolution, and streamlined workflow, MIDI 2.0 empowers musicians and producers to achieve new levels of expressiveness and creativity.

Backward compatibility with MIDI 1.0 and the already available Bluetooth MIDI, allows you to seamlessly adapt to future MIDI 2.0 devices, while retaining your collection of excellent MIDI tools already in your studio.

The full MIDI 2.0 specification can be found via The MIDI Association.

  1. I wonder if MIDI 2.0 also increases the amount of available midi channels. When using MPE capable software/controllers, all 16 channels are in use which means that it’s impossible to switch between instruments by switching channels. Anybody here who knows anything about that?

    1. It does not increase the available MIDI channels on traditional MIDI 1.0 devices that use for instance 5-PIN DIN MIDI ports. That will be limited to 16 MIDI channels. Nevertheless, when looking at USB and MIDI 2.0, I believe it will be capable of transmitting 16 x 16 = 256 MIDI channels.
