Hello (First of all, sorry, I didn't find the time to write my patch files and send them here) I'm exepriencing some troubles, quite weird and not so reproductible, with MIDI synchronization between seq24 and other stuffs. I've got to describe a bit my setup to make this mail understandable. So, I use Sooperlooper as Jack Timebase Master, and as a live-looper, of course. I then use seq24 as a a sequencer controlling several instances of AlsaModularSynth, and one of Tapeutape (a sampler), and also Q Light Controller (a light controller package). I've made some patches in seq24 so that I can bind a MIDI control to start and stop playback. Now, here is the problem: Sometimes, all work fine, when I hit the playback MIDI binding or the space key, sequences begin to play with tempo given by SooperLooper. I can change SooperLooper tempo, it works really fine. I mean, starting playback is "instantaneous" (as much as possible) with the MIDI Signal. Some other times, it's not the same. When I hit the playback MIDI binding, there is a really big delay (like 5-10s) before it begins to start playback. One important thing is that everything is launched using a bash script, so that the init sequence is the very same each time I power up the computer. The only thing changing from one session to another is the time when I've to unplug/plug my MIDISPORT interface as it's not detected by udev when plugged at boot. Another important thing is that when it doesn't work, it doesn't work until I powercycle the COMPUTER!!! I know you probably cannot give me a solution or answer with so "etheral" informations, but I first would like to know in which direction I should look. I'm not very used with MIDI synchro, and perhaps it's a really basic error, but I cannot figure out what it deals with. Thanks a lot. Aurélien -- Aurélien |
