MIDI Spec A/B/DIN question

[Jesse Johannesen]

I'm relatively new to the TRS convention for MIDI connections, so I started poking around the net reading specifications, etc.

One question I have - the TRS spec seems to limit the length of a cable to 2 meters (approx. 6 feet).  The original MIDI spec for DIN connections is 50 feet.
Can you in fact use TRS MIDI for distances longer than 6 feet?  Does it depend on the transmitting and/or receiving device?  Does it differ if you use a TRS to DIN adapter and connect the device to a traditional DIN MIDI socket?

Also - given that a number of MRCC slots have all 3 MIDI types, can the MRCC support parallel connections (i.e. - using both MIDI A and DIN for a slot?)
understanding of course that the information sent will be identical.

thanks

I can't say I've researched the range issue yet, but I can look into it. From what I understand however I believe you would be able to use both out ports at once, I'll report back once I get confirmation.
