There was a problem hiding this comment.
15.84... used to be calculated as a factor from MAX_dB, if we every adjust MAX-dB in the IDL file, this needs to be adjusted as well, so it shouldn't be hardcoded.
I.e. just add another constant next to the MAX_dB constant definition and use that for this registration, so it's obvious that both have to be adapted if we touch the constants in the future.

This ports all properties of the MidiSynth to C++ (except for object properties SNet/PNet).
I had to fix a bug in BsePcmOutput (first commit), because setting the volume on the output object had no effect, but I wanted to test my code.
To have 1:1 the same ranges, I introduced constants for BSE_MIN|MAX_VOLUME_dB, but maybe this should just be hardcoded to -96 / 24. For the new max midi channel constant I think a constant should be used (maybe moved up to the other constants).
I noticed that some property idl constants don't combine properly. If you write Range (... GUI STORAGE ...), this expands to "r:w:G" "r:w:S" - so instead of getting a "G" hint, you get a "Gr" hint. Here I used STANDARD as ported property type, to work around the issue,which has both "G" and "S" hints. Not sure what is intended here, but adding ":" at the beginning and end of each property constant would allow using both versions for a GUI & STORAGE property.
