Hello
MIDI module is not busy because there is no device.
To summarize:
  MIDI 3.14 is the Acorn version number of the MIDI module, but it was not 
a USB version, it was for a Podule.
  Harriet's MIDI 3.14 module is a renumbered version of Rick Murray's 
module because Rhapsody wanted this version.
No more needed.

To day if you have MIDI equipment, use the Rick Murray/Dave Higton/Colin 
Granville module, otherwise use Pete Everett's MIDISynth module, which is 
a good solution for those without equipment.

Rick's module works well with Maestro, Rhapsody4, for MIDI files with 
!Player , DigitalCD and under emulator !MelIDI (unfortunately I only have 
the demo version)

Pete Everett's mod is fine too, all the programs listed above should work.
Pete's !MIDIPlayer application is very good and according to the Forum 
games can benefit from the MIDI module.
