Tried using Jammr as a master clock to my DSI REV2 via USB and it was pretty erratic, like +/- 20 BPM.

I also experience problems with the midi clock. I have a Korg KROME EX, which I tell to take midi clock info over USB, jammr also sees my Korg fine, it also transmits the clock to it, bpm changes are well reflected in my Korg's sequencer, BUT if you stay on the same bpm for a longer period >1 minute, both the jammr's metronome clock and my Korg's get out of sync - still correct bpm but out of sync.
My idea was to program loops in the Korg to have a chord progression going all the time in the background while still being able to stick to jammr's metronome - this seems impossible.
Any ideas ?

One thing I have found is that if you join an empty room at BPM 120 then i seem to get a lock. No drift. However once I change the BPM the midi clock getting sent to my drum machine does change and its synced for a couple of minutes then it starts to drift. I try to put a drum machine into a jam to keep people on track as no one appears to follow the metronome. But have found i spend more time disconnecting and reconnecting trying to hunt down the elusive sweet spot of soundcard settings and inputs.
Feels like witchcraft. The only thing i can think is its at the Jammr end as opposed to mine. As I have 3 midi devices that all stay locked together once they get the clock. Its the Jammr metronome that is actually drifiting. Which is fine when people just follow the metronome as everyone drifts together.
Kinda weird.

I don't think for a second it's your setup leeastone. Introducing a network into the mix just makes a few new problems to overcome.

It would also be sufficient if somehow a re-sync could be triggered after every interval … Somehow my sequencer only syncs after a bpm change.

I'm finally connected and getting MIDI messages on tempo change, but it's not changing my tempo whatsoever. I'll keep hammering.

The Jammr app is running a metronome that doesn’t drift. Have the app divide that clock into 24 pulses per beat and send a MIDI clock (248) every pulse.
