Using JACK transport, they also start at the same time (sample accurate). Its possible for an application to be one or more JACK cycle times behind or before. This offset would be constant while playing (and would be an bug of course). What you probably expect is that the midi tempo of two JACK applications is in sync. But JACK has no idea about the mapping of samples to midi ticks and is not designed for such kind of tasks. What you need for this is some kind of a global tempo map. The only way to sync midi applications is for now to send a midi data stream from the midi master application to all midi slave apps containing midi sync information. Werner |
