[gmpi] Re: closing reqs 3.8

At 4.23...

"If GMPI is to succeed at all, it must be interoperable with the enormous installed base of MIDI applications, plugins, and devices. Pure MIDI, however, is too limited for GMPI's use. GMPI plugins and hosts need more flexibility than simple MIDI can provide. The notion that a parameter requires a fixed MIDI CC number is obsolete. In the software world of control signals, any CC should be able to go to any parameter."

...we should probably define 'pure MIDI' and 'simple MIDI' so people know which of MIDI's many, many aspects you have in mind there. For example, the MIDI event message transport layer per se doesn't force any particular interpretation on any controller number; really its flexibility can't be beat. Perhaps you're confusing MIDI per se with unfortunate limitations in the ways MIDI has been implemented in previous OS and plug-in APIs?

Can I suggest replacing the above with the following?:

"If GMPI is to succeed at all, it must be interoperable with the enormous installed base of MIDI applications, plug-ins, and devices. However GMPI's handling of MIDI must take care to preserve the inherent flexibility of the MMA MIDI specifications, and avoid the numerous harmful assumptions and other limitations on MIDI message contents and semantics from which some previous OS and plug-in APIs have suffered. In particular, the notion that a plug-in parameter requires a fixed MIDI Controller number is obsolete; in the software world of routable control signals, any MIDI controller message source should be able to drive any GMPI plug-in control (parameter)."
