Hi all, I'm currently writing a very simple step sequencer. It runs fine and has many features I wanted :P But the sync causes me headaches. I can start my sequencer more then one time(of course), so they all start in a sepereate window and have an own midi out thread. My problem is to sync them all. I thought that the main app, from which I launch the step seqs, has got an own thread, which count a whole tact and starts the selected midi out thread of the new seq. But as it is possible to use crazy length(as 1/7 or so) I think my sequencers will get out of sync. And if one sequencer hangs, it will get out of sync, too. But how can I get it back in sync? Questions questions questions... I hope you understand my problem and have a solution. p.s.: I want to keep it platform independent, as it uses rtmidi and sdl which run on all audio platforms.
