Backbone crashes in GigPerformer 4.5

Dear all

Backbone is fantastic plugin and i would like to use it live.
But GigPerformer crashes when i close the plugin.
Anybody who as the same problem or solution?

Would there be a chance that Steinberg would make a multi backbone engine in the style of groove-agent to load up multiple instruments (16 layers) in one instance?
This would be great and much more cpu friendly for live use…
