Hi all, I'm not sure if I've posted to the right forum, but I'd appreciate any advice. I've just started to get an interest in the Seq4 and would like to build one. After browsing through the Midibox site it seems there are several options to building one and I'm a little confused. What modules do I need to build, I've built an edrum recently, so I'm quite happy and confident in building as much of the seq myself including etching PCB's. Any help and advice would be appreciated, as I'm little lost as to where to start at the moment.
