Selected Test Results (selected in 'Test Results' table below)
tested with Version 2.01
Almost everything. Chosing effects and amplifiers works and loading presets and samples does work, too. Just played one hour around with it and I am totally astounded what is possible this time.
Tested everything with fst as vst wrapper and it works out of the box.
What does not
Loading presets does not work from the beginning. You have to copy the Presets Folder to a path where there's no space between characters. And voilà: it will load all presets. Same procedure with Metronome Sounds.
You're even able to use midi with Guitar-Rig.
What was not tested
Some details like saving some things.
