Yes the whole process is quite confusing. It starts confusing me even when I install an update of T-Racks. it always installs everywhere even the plugins I don't own...
The sounds installation process is even worse.
Especially if you want to install the largest possible chunks of files on a different disk...
I found the places where all files, samples, library info, presets, etc. etc. etc. are installed and was able to move them, but again, it took me a lot of time and it's VERY confusing.
Thank god the overall quality is great for the price !
