PS: The day when I had this trouble I used extreme "Frames/Period" and "Periodes/Buffer" settings, sometimes there were asyncs, xruns (without hearable glitches), but not while listening and getting this bad sound, there were no messages by JACK. Today I used normal settings.
I repeated it, running jack with this extreme critical settings, Oberheim --> system capture_1 --split--> jkmeter left and right, phases are fine and without playing the Oberheim a little bit less between 0 at +, than when using Qtractor. Even this bad settings don't cause phases for jkmeter BUT when I listened to it by headphones I can hear that the sound is bad on mono. So the voodoo isn't voodoo, but wrong settings for JACK, even if there are no messages by JACK and even if jkmeter didn't notice it, it's hearable. Anyway, this dosen't happen when using good settings for JACK :). > Fons Adriaensen wrote: >> jkmeter started with the -C option. > > 1. > > Qtractor > imported a sine at 440Hz mono > > Qtractor Master/out_1 connected to jkmeter in-1 and in-2 > phases are > fine, at +1 > Qtractor Master/out_1 connected to jkmeter in-1 and Qtractor > Master/out_2 connected to jkmeter in-2 > phases are fine, at +1 > > 2. > > Audacity > imported a sine at 440Hz mono > > Audacity out connected with Qtractor in (not visible by any JACK > connection GUI) and Qtractor Master/out_1 connected to jkmeter in-1 > and Qtractor Master/out_2 connected to jkmeter in-2 > phases are fine, > at +1 > > 3. > > Anyway, an Oberheim Matrix-1000 connected to the sound card channel 1 > and than connected by JACK system capture_1 to Qtractor Master/in 1 > and Master/in_2, while Qtractor Master/out_ was connected to system > playback_1 and Qtractor Master/out_2 was connected to system > playback_2 the sound WAS bad, when I rooted the subgroop by my mixing > console to mono AND it was not the mixing console, for other sources > doing this the sound was fine. > > 4. > > Oberheim Matrix-1000 connected to the sound card channel 1, system > capture_1 connected to Qtractor Master/in 1 and Master/in_2, Qtractor > Master/out_1 connected to jkmeter in-1 and Qtractor Master/out_2 > connected to jkmeter in-2 > phases are fine, at +1 but without playing > the Oberheim phases aren't at 0 or +1, but a little bit beneath 0 at +. > > Checking it by headphones on mono the sound is fine :). > > This is very strange!
