Timing specs/precision
#1
Hi all!
Would it be possible to share the timing measurements for this unit's routing function?
Like sending a pure MIDI clock signal (please check with an oscilloscope that it is *very* neat!) and then measure on the MIDI outputs how the signal looks like (delay, jitter, ripple, ground noise/offset, voltage and current).
I'm struggling in finding such a MIDI router which really does not deteriorate too much the MIDI clock signal...

Thanks,
F.

Hello Flavio,
it seems that the conductivelabs are a bit busy, then I'm answering to help ...

you will find all the infomation concerning some early measurement here :
https://www.kickstarter.com/projects/the...ts/2656230

to summurize: That's early measurement on the prototype.
Latency is about 1.4ms (from midi input to all midi outputs, 1.4ms is the worst midi out value) and jitter below 400us. There is almost no latency between all the midi out.
(personnal comment: compared to other midi routers -without processing-, 1.4ms is equivalent to the best in class exisiting midi router latency).

This is for sure without some potential future effect processing etc ... it will increase the latency but I think that we can be confident. The MCU used is powerfull enought.

Darryl explained they will continue to monitor the latency/jitter.

For the MCU, the Darryl's communication:
https://www.kickstarter.com/projects/the...ts/2636355
(there is another communication about this point which describes the prototype MCU, sorry i've not been able to find it again).

hope it helps ...

Yomanfree, thanks for sharing that link to the Kickstarter post. That's what I would have shared.

We will publish some new Latency and Jitter specs when we are about done with development.

I can't tell by your message what is the specific problem you are trying to solve. Is it latency and jitter? What is the symptom? That is, how do you know there is latency and jitter, can you hear it? If you can hear it, its bad  Dodgy  I assume you are using 5 Pin DIN and not USB since you asked about electrical characteristics of the MIDI outputs?
