Timing specs/precision

Is the latency constant, or does it vary?

I very strongly disagree with another commenters' assessment that timing issues are more often a product of the midi implementation of the receiving advice.

I am highly interested in a potential clock offset feature. It would also be welcome if the MRCC could automatically compensate for the latency it introduces. For example, if it introduced 1.4 ms of latency, clock signal would offset by -1.4ms.

Negative offsets are achieved in the E-Rm multiclock by filtering out the clock signal for 4 pulses, similar to 1 bar of pre-roll on a DAW recorder.

Of course you're free to disagree, but when you can prove with accurate measurements that the master MIDI clock is really tight, where do you think the issue will lay? In the MIDI cables? :-)

How would an automatic latency correction work with MRCC, when it should compensate for the latency it (the MRCC?) itself is introducing?

Negative offsets are actually simply positive ones - when the clock is stopped, you cannot apply a negative offset. It would be like saying "start 1.4 ms before I tell you to start"! :-)
