Not that this matters to me much, but in DIN sync the MIDI data pins 4-5 are optional, so the mandatory part of DIN sync protocol can actually be shared with MIDI on the same output (using custom cables and some care ). Pyramid offers MIDI and DIN sync on one of it’s output ports this way: https://squarp.net/static/50b525404c07f5376161b8f5fe04d357/fc32b/din_sync_routing.webp
