Description:
WaveBurner only lists a few Waves plug-ins although a lot more are installed.

Explanation:
In WaveBurner the Plug-in folder is set to the Waveshell folder. As a Waveshell can only load one plugin at a time, there are only four Waves plugins available (WaveBurner allows up to four plug-in folders).

Solution:
Please choose the Waves plug-ins folder in addition to the Waveshell folder in "Edit->Preferences...->Plugins". After restarting WaveBurner all installed Waves Plug-ins will be available.
