The heart of the setup is the Sequentix Cirklon. Its a very powerful hardware sequencer made by this one guy in Scotland. It controls everything else (that is controllable) in the setup. What is great about it is how easy it is to change everything so quickly. Its very non-linear in how it works. I'm also taking a Roland TB-303, Niio Iotine Core, MFB-522 drum machine, Eventide Space, Strymon Timeline and MPC 1000. Some of the equipment in the studio is too delicate to take, like the ETI 4600 so I've sampled it into the MPC.
