These are the sessions for the Piano Groove Tutor. Although they still can be played in the old 0.5 version, the format has somewhat changed since version 0.7, for example in version 0.5 the metronome tracks will not be audible and some instruments may be on the wrong tracks ... so really you should download the latest version on this page to ensure everything will work ok. If you have downloaded the sessions for the older version, they work equally well in version 0.5, so all you need to do is replace the executable jar file and add sessions in the sessions folder as they become available.
All new sessions and updates will be announced here. Once a session is downloaded, you can add it to your application by navigating to the folder that the Piano Groove Tutor resides in, open the sessions folder and paste the session jar file into it.
The download procedure in some versions of Internet Explorer does not recognize jar files. Firefox can determine correct mime-type by extension first, and check header information to find out if there's a congruent match, Internet Explorer unfortunately doesn't do that. So if your session files, after download, have the 'zip' extension, rename these extensions with 'jar'. You may need to untick Hide known file extensions in Control Panel → Folder Options → View to do this.
