You can find tutorials, jams, and a nerdy studio tour there.
If you're looking to build a system based on the Behringer System 55, I've created a template for that here:
This shows everything as it comes in the box. I have rearranged my own rig for ease of use, placing envelopes and VCAs together in pairs, and removing one of the oscillator controller modules to make space for other stuff. I'm happy to answer any questions.
Cheers,
Monodux
