I clearly mentioned. ONLY FLAC.
With FLAC ONLY it does not work.
With Wav + wma it DOES work.
Yes, you did. Thank you for confirming that PG Music apparently did change their approach and did not include WMA in the new full audiophile download. This is news.
I can bring some light to the topic.
An "only flac file version" install of Realtracks will not work with both in the BB and in the plugin.
This was reported in pre-release and confirmed by PGM as an invalid installation method. (that fix is pending the Holiday break)
I use the plugin with .flac files with no issues.
The only working installation that works is to install both the .flac and .wma files and more importantly the .db0 and db1 files required to make the entire thing work.
If you look in your Realtracks directory for a particular instrument and see only .flac files you have a improper installation.
If you have the shipped disk, run the .wma installation on top of your .flac installation and it will fix the problem.
