segfault macos: ErraticInstruments::MPEToCV

adding/removing ErraticInstruments::MPEToCV via package manager in a patching workflow session causes segfault on macos w/ rack 0.6.0. trace shows macos MIDI issues -- would you like a full stack trace?

terminating with uncaught exception of type RtMidiError: MidiInCore::initialize: error creating OS-X MIDI client object (-50).

Hi dirkleas, does the same happen with you use the MiditoCv module? They should act very similarly... a stack trace would help but I'm not sure I understand exactly what you are doing to trigger this, otherwise I could try and repeat it myself :)

[dirkleas]

I was generating dox patches of varying size/complexity/number of modules as well as testing multiple File.Revert invocations. it occasionally occurs with MiditoCv as well -- I'm assuming the root cause is the MIDI macos service/usage, but it's not clear whether it's a Rack core thing or a module API or instance thing

There's some new updates to midi and seems like there are still some glitches. I'm guessing the problem is the underlying midi library Rack uses.
