Linked here (https://framadrop.org/r/rTdz7G5_aH#PkFaWVQBz0PCz70lRVf0NrPrwu8YIA7GcAYledl+uj4=) is the session file. So he's on his machine, and I'm on mine, I hope that this is even possible, given the "Directory" absolute path field in the XML session file... why can't Qtractor use this "//" relative syntax that Blender uses? This is really weird... Qtractor does not hang, everything is fine, I just can't play (I can move the playhead by shift-clicking, but not by fast-forward to the next marker) and no messages in the starting shell..?

Aha, I'd love a setup that works so well that 1024 would be a "huge" value but sadly, that's basically the everyday setting (well, 512, but it's still huge in "normal" standards) and no, it doen't do it :( but thanks for your quick reply, Holger!

What would prevent the playhead from moving in a given session? A friend of mine and I are stuck in a big Qtractor session that will not start on either of our machines... This is kind of urgent... We tried restarting everything, then fiddling with Qtractor's transport options, then tried external jack transport clients... No luck. Qtractore won't even move the playhead from marker to marker! :( yPhil -- Yassin "xaccrocheur" Philip http://manyrecords.com http://bitbucket.org/xaccrocheur / https://github.com/xaccrocheur |

Nope, I'm stuck. I tried another keyboard, still the same weird issue: I can type text in file dialogs, I can toggle the mixer with F9, I even can use my custom F1 to F4 shortcuts, but I can no longer create a clip with C, or even copy and paste things with Ctrl+c/v What is really weird is that in the shortcuts window, every key works!

Hello, developers. I want to report some bug. When I unmute or solo one track of session QTractor plays it with a random delay. To reproduce the bug you can add some long (~30 minutes) clips in wave 24 bit 48 kHz format, hit play button and then press twice mute button or solo. |

Hi everybody, On the wrap of the late min...@c-... Berlin (April 8-10) [7][8], where this Yet Same Old Qstuff* (continued) workshop [9] babbling of yours truly (slides, videos[10]) was taken place. There's really one (big) thing to keep in mind, as always: Qtractor [1] is not, never was, meant to be a 'do-it-all' monolith DAW. Quite frankly it isn't a 'pure' modular model either. Maybe we can agree on calling it a 'hybrid' perhaps? And still, all this time, it has been just truthful to its original mission statement--modulo some Qt [2] major version numbers--nb. it started on Qt3 (2005-2007), then Qt4 (2008-2014), it is now Qt5 full throttle. It must have been like start saying uh. this is probably the best dot or rather beta release of them all! Now, Qtractor 0.7.7 (haziest photon) is out! Everybody is here compelled to update. Leave no excuses behind. As for the 'mission statement' coined above, you know it's the same as ever was (and it now goes to eleven years in the making [11]): Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Hey, Spring'16 release frenzy [7] isn't over as of just yet ;) Keeping up with the tradition, Qtractor 0.7.6 (a hazier photon) is released! Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Fortunately a lot of hardware synth allow to ignore one or the other MIDI command, but a sequencer should allow to turn off and on a feature that reset all controllers, especially between segments, parts what ever else they are called. |

However, neither of them seem to have this problem. If I re-load a session, not only are all the tracks as I saved them, so is even the song position and the complete state of Yoshimi at that time. I'm not going to get into arguments as to which is right or wrong, but it does rather take the shine off. I can sort-of get round it by bedding in CCs at the start of each track although that's rather tedious - but what other CCs do you set? It would seem to me the only valid CC for a sequencer itself to set would be 121 - reset all controllers. That would not be a problem, because one of the user settings in Yoshimi is to ignore it! (there is a sequencer that sends this at the beginning of every segment of every track). -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

If I understood this feature correctly you can switch it off with midifilter plugin(s). I tried MapCC and let it change CC7 to CC0. No volume changes were received by the synth plugin in that track. So this might be a solution for Will. |
