Literally what are you talking about. the device is barely thick enough to fit a 3.5mm jack, DIN connectors were never on the table. frankly it's a bonus it has MIDI at all. who cares what your $2000 'proper' synths have.

Plenty of thinner gear has real MIDI ports. I hate the adapters and USB MIDI. Put a lump on the back, that'd protect the knobs a bit too.
