[gmpi] Re: MIDI: Proposed Requirements (wrap up try #1)

I wonder if it would be possible to give the user access to the graph.

My reason if in the case of MIDI controllers and/or synths which get the
MIDI spec wrong.  Might it be possible to allow the graph to be opened in a
synth with an "advanced" tab where a user could reroute the MIDI events to
something else, or constrain them in some manner?  For example, my MIDI
controller sends cc64 sustain pedal messages at some events other than 0 and
127.  This is acceptable within the MIDI spec, but some softsynths only
respond to 0 for off, and all other events as on.  So, my controller is
sending a MIDI-correct off, but because it is not 0, it is not interpreted
correctly by the synths with incorrect MIDI interpretation.  The workaround
is an MFX called SustainFix from www.tencrazy.com which constrains 0-63 to 0
so that these synths can read my note off correctly.  Rather than bother the
developers with it, as I have been, a self-help graph where I can plumb the
MIDI myself would be preferable.  I'm sure that there are other incidents of
soft synths not following the spec properly, and of MIDI controllers also.
With the planned architecture, it seems like it might be possible to
intercede between the miscommunicating MIDI controller and soft synth.
