How TRS MIDI Works
Many MIDI instruments, effects, and modules now support MIDI over smaller “minijack” connectors, but their implementations > vary:

Type A (now the MIDI standard)
e.g.: Korg, Make Noise
Type B
e.g.: Arturia, Novation
TS sometimes called Type C or Non-TRS
e.g.: Expert Sleepers, Beatstep (Original), MFB
