An even better MIDI extender?

From a company based in the UK 8)

LNDR is a master and slave pair that allows MIDI to be sent accurately in both
directions at the same time, across distances of over 500 metres (1640 feet)
using a standard CAT5 cable. This is over 33 times the distance achievable
using standard MIDI cables. The Master unit is mains powered using the i
ncluded PSU.

The manual:

Seems to be a lot to like here esp if itr works as stated.
Bi-directional MIDI, Hmmm and a max of 1600 ft apart.

A MIDI signal applied to the MIDI IN of the master will appear at the MIDI
out of the slave. Similarly a MIDI signal applied to the MIDI IN of the slave
will appear at the MIDI out of the master. You can send signals in both
directions at the same time.

Artisan Instruments (the uMIDI people) sell an extender pair for ~$70 that uses RS-422 which by standard should be good to 1500 meters...

What kind of latency are we talking about (or is it negligible)? I didn't see any info on the website about it but I'm intrigued by these.

Additional latency would be negligible with RS-422. The slow 31.25k rate for conventional 5-pin MIDI would remain. A better approach when possible would be to keep all MIDI traffic on USB and use RTP-MIDI for longer distances using ethernet. That gives a MIDI speed that is hundreds of times faster than 5-pin with negligible latency overall.
