Re: [Guidolib-devel] API for score query

[Jonathan A. <joi...@gm...>]

Hi Dominique,

I've checked out the 'dev' branch (and the engine version is indeed 1.6.3). Thanks for the update and the example code!

I can see GuidoGetMeterAt and ARMusic::getMeterAt in the engine code, however it looks like the file MeterVisitor.h (and, presumably, its .cpp counterpart) is missing from the repo. I double-checked by downloading a snapshot of commit 6db983 on sf.net and couldn't find those files either.

Cheers,
Jonathan
