I did have some problems starting out, but everything woks fine now.
Check the archives, there is something there about how I was losing
audio when running with MIDI.

I think it was actually also a problem with Csound5? It had something
to do with the MIDI callback. But my problem was that I could perform
an MIDI instrument, but then if I recompiled it the MIDI was lost. In
the end I think I just had to make sure I called csoundPreCompile().

Maybe rtmidi can be set to null and a device selected automatically when a callback is set. It doesn't make a lot of sense to use it another way.

Cheers,
