the way I am casing my SEQ V4 (STM32F4) there will be a 50 cm. distance between the Core and the MIDI sockets.
either I can have the MIDI I/O and Quad IIC boards close to the Core, and 50 cm. cables to the sockets, or I can mount the boards to the back plate, and have 50 cm. cables to the Core.
Is it a cable length problem with the MIDI I/O and IIC boards, like it is with the DIN/DOUT/AOUT?
It would be a lot easier to just stretch 3 flat ribbon cables from the Core to the boards, than 2-3 wires from each IN/OUT
(with 4 IN and 12 OUT, that’s 44 wires soldered / crimped on each side :sad: )
Looking at the schematic I see no reason why you shouldn’t be able to use a 50cm cable between Core an MIDI I/O module. For the Quad IIC module I don’t know for sure, but I would assume it should work.
