It’s been a long time coming, but MIDI now officially has added MPE and “capability inquiry,” opening up new expression and automatic configuration.
MIDI, of course, is the_lingua franca_of music gear. AKA “Musical Instrument Digital Interface,” the protocol first developed in the early 80s and has been a common feature on computers and gear and quite a few oddball applications ever since. And it’s a bit of a myth that MIDI itself hasn’t changed since its 80s iteration. Part of that impression is because MIDI has remained backwards compatible, meaning changes haven’t been disruptive. But admittedly, the other reason musicians think about MIDI in this way is that the stuff they most use indeed has remained fairly unchanged.
Engineers and musicians alike have clamored for expanded resolution and functionality ever since MIDI’s adoption. The announcements made by the MIDI Manufacturers Association aren’t what has commonly been called “HD MIDI” – that is, you don’t get any big changes to the way data is transmitted. But the announcements are significant nonetheless, because they make official stuff you can use in real musical applications, and they demonstrate the MMA can ratify official changes (with big hardware maker partners onboard). Oh, and they’re really cool.
