I am thinking of ways to add SD card to the front panel and it would be nice to have a slot in the middle of the encoder row. I suspect there is not enough space to add a card edge connector from a floppy cable, but since i don't have neither sequencer pcb nor connector yet, i can't verify it. If somebody has got a card edge connected floppy connector feel free to post the dimensions of it... one obvious limit is the height of 10mm... maybe there is some low profile connectors available...
