I see you're using a lot of Erica TUBE/Fusion modules as well as the Plasma Drive. What is your power supply situation?

To add some interest... a Trigger Riot, for complex pattern generation might be fun for your drum situation.
A Worng Electronics Vector Space for complex modulation possibilities.
A Noise Engineering Mimetic Digitalis for adding some stepped CV modulation into the equation (lots of fun hooked up to the Trigger Riot).

new rack has 5 separate doepfer PS. it was custom built with my modules in mind, so power left to spare :)

really like that Vector Space and the Mimetic Digitalis but both appear to be out of stock :( lots of good suggestions so far but most of the modules aren't easily purchasable. thats Vector is wicked cool though!
