Summary0001497: Zxx Macro support for seeking
Description

CSoundFile::GetLength currently doesn't support Zxx MIDI macros at all, mostly for technical reasons. While it might not be possible or desirable to add full support for any kind of MIDI macros to this function, it should at the very least support local MIDI macros (i.e. anything that's not passed on to plugins as raw MIDI messages).

This might be done by splitting the parsing of the MIDI text macros and evaluation of the resulting MIDI data into two steps that can be carried out independently, and allow the second step to only handle local macros. But even with local macros there needs to be a distinction between macros that just modify channel state (such as filters, which are arguably the most useful macros for this use case) and macros that are local but still modify the module state (such as plugin dry/wet ratio) - the latter may only be evaluated if GetLength succeeds with seeking. When GetLength isn't used for seeking, macros should not be parsed at all to save time.
