If a MIDI message is valid (i.e., not corrupt, and uses all legal values), no error will be returned. Whether or not a
message produces a change in behavior on a MusicDevice is entirely dependent on the specific Device and the
preset (instrument) which is loaded into it. There are fair number of MIDI control change messages (0xB0) which
affect most instruments: Volume (7), Expression (11), Pan (10), etc.
Channel pressure will produce an effect if the currently-loaded instrument has a connection defined which indicates
what it should be controlling (there is no default value for this unless you are importing DLS or SF2 bank instruments).
General MIDI Portamento and Poly Pressure are not supported in the current release. Instruments imported from Logic
and GarageBand will honor any portamento used as part of those instruments.
