the bridge client/code that interacts with the physical port is expected to
normalize incoming messages that use running status. not doing so violates
the API contract.

ardour maps can be bound to arbitrary byte sequences but i am not convinced
they will work for multiple events. not something i've ever tried or
thought about.

the problems with controllers come from the almost absurdly varied ways
that h/w manufacturers have chosen to use them.

not true. any action defined in Ardour can be bound to OSC. there is no
linkage between the keyboard shortcuts and OSC.
