OK! I have read this now.
I find the following to be an overcomplication. First you have:
| <base path>/program
| Make a program change on the plugin. Takes two int arguments, for
| bank and program number. (required method)
.. and then just after:
| <base path>/midi
| Send an arbitrary MIDI event to the plugin. Takes a four-byte MIDI
| string. ...
.. which covers program change very nicely and even covers multitimbral
synths receiving on several channels (which is for some reason not
covered by the required method?)
I also find that in
| 2. Discovery and Startup ...
.. it would be so much much simpler to just have two commands:
show_ui(), hide_ui() or perhaps: ui(TRUE), ui(FALSE)
.. and let the developer spawn a thread, a process or a program (recommended!)
which will take care of the user interface. The plugin "knows" its own
structure and can present a useable layout. The interpreter of a query will
probably just run out of screen real estate.
For reference: I have 16 channels with 164 parameters each ...
That is to the unsuspecting interpreter a humble 2624 parameters
on screen :)
