During the Jam Machine I felt I would not have enough time to build a mod of my own and AtomicBlom felt the same so we combined our forces and worked on this together. I didn't contribute as much as I would have liked to this mod as I was quite ill this weekend but I did contribute some models and the concept of a physical interface that turned out really nicely.
I plan to return to this mod and implement the cables. We made a start on them but I was a little too hopefull on the complexity of the model with blockstates so it wasn't finished. We also have a controller block that can control multiple sequencers connected directly or via cable.
