The MIDI Association is announcing at NAMM 2022, the addition of MIDI 2.0 capabilities to Analog Device’s A2B ( Automotive Audio Bus ).
A2B® is a high bandwidth, bidirectional, digital bus, capable of distributing 32 channels of audio along with MIDI control data plus clock and power over a single, low cost, unshielded twisted-pair wire.
Consider what this could mean in application if this is generally accepted and used. A network of devices could all be connected with a computer device as well.
