Re: [Jack-Devel] synchronization with Jack transport

Yes I often use Ardour and Mixbus32c  but I do not actually use it for this problem: I just use seq24, seq64 and Giada: I am on ubuntu studio64 with 2 multiface II sound cards + ESI M4U Xt midi usb interface _/Try to create a minimal setup, which still exhibits the problem/_: With seq24 I control 4 synthesizers : SE-02, Andromeda, Solaris and a Q Rack with midi pattern + the DSI Tempest set as slave and all are connected in seq24 interface. The seq24 different patterns are connected to the different synthesizers by this way: just right click in the pattern and choose the midi bus. In the option menu of seq24 I put on the midi clock on the midi channel of the tempest : [4] 28:3 (ESI M4U XT midi 4) ---> on At this time everybody work fine but when I wanted to record the pattern loops in Giada (audio software) I had to connect Giada and seq24 to jack to make them synchronize and at this time I had the problem with the Tempest: 77 bpm instead of 120 bpm. At the beginning I thought that it was the fault of Giada but when I eliminated Giada of the setup, the problem persisted. It appears when I connect seq24 to jack. So to summarize the moment when the problem appears, I do not use audio software, only midi with seq24 which drives the synthesizers and the Tempest as Slave. To have a minimal setup now which still exhibits the problem, now I have only seq24 connected to the Tempest. _/ /_(I also tried  to connect the Tempest to my master midi i/o multiface but the problem persist.)
