Making the connectors properly takes a bit of practice, but it's not too hard... You might screw a couple up before you get it right, but once you figure out the technique, the IDC cables "just work". When you apply pressure to crimp the cables, make sure the pressure is perpendicular to the connector, don't apply uneven pressure, or pressure at an angle. If you have trouble with a connector you've made, test it with a multimeter to make sure all wires are connected, and no wires are shorted to their neighbour. Make sure the two connectors are orientated properly before crimping them on to the ribbon cable - there are "pin 1" indicators on the connectors, make sure the Pin 1 indicators on both connectors are both attaching to the wire you've designated as Wire 1. Take a minute to think about orientation before crimping, there are several different possible ways to attach the connectors to the cable, and only one of them is right. There are also little protrusions on the connectors that fit in the connector shroud on the PCB, so you can only plug them in one way if you're using shrouds on your PCB... The protrusions are marked on the PCBs... Just take a minute to think about orientation before crimping the cables, and you'll figure it out - it's easy once you get it, but it's hard to explain in words. https://www.google.ca/search?&q=idc+connector And make sure the cable is orientated properly when you plug them in (although for most of the connections on the MIDIbox SEQ other than maybe the LCDs, it's unlikely anything bad will happen if you get the orientation wrong, or if you've crimped your connectors on backwards, other than that the connected mudule won't work properly.)
