The MIDI Beat Clock is not related to network latency. MIDI is only local to your computer. jammr does not transfer MIDI over the network.Another way of explaining the current clock drift behavior is that jammr knows the right time at which to emit a MIDI Beat Clock message, but the MIDI message is sent at an arbitrary point in time afterwards. The precise timing currently depends on your computer or you could say it's left up to chance. Adding a timestamp will ensure that the receiver knows exactly when the MIDI Beat Clock message is supposed to happen, regardless of when it was actually sent and received. This should significantly reduce drift.Don't worry, I will get to this if no one else does before me. At the moment it's looking like 3 weeks.

Thanks for the response, really appreciate it.

One thing to consider, why is it that a VST drum machine can stay in sync without the same issues as MIDI clock? Maybe there's a fix there?

That would be stellar. My coding is a bit rusty and would probably a while to get solid build let alone write a fix like this.

Anyone on windows want to try this older 32 bit VST to see if you can get stable clock from it?

I tried it, didn't seem to do anything.

Keep in mind that MIDI Beat Clock is a convenience feature for syncing the tempo automatically between apps/devices.

You can play in sync simply by manually setting the tempo in your drum machine instead of using MIDI Beat Clock.

This is not a good solution, without clock sync the drum machine will drift out of time. Maybe thats fine if its just a drum machine, but you cant have multiple jammrs using electronic instruments that rely on clock.

eb_liveDrums: Just until the MIDI Beat Clock is improved.

I have started working on this.

The rewritten MIDI Beat Clock is now available in the jammr 1.2.90 beta release:

Would be great to hear if it works for you!

tried my first every session last night and midi sync was the first thing I reached for. tried using Logic and outboard to try and drop in additional rhythms to somebody else's drum drack / produce in sync synth arpeggios & sequences, but no joy really.

checked the external midi radiobox on the midi preferences. I think I may have experienced sync once for about 30sec over a 3 hour period.

am I missing something or is this roadmap stuff on the app? should I give up for now and just strum along?

Either way it was SO nice to get some musical interaction after so long!…..
