ventosuswhat is LV2_Object_Body.id for?09:08
ventosusspec says it should be: URID, or 0 for blank.09:08
ventosusI've only seen it used by Ardour, which sets it to 1?09:08

rncbcrgareus: hi15:40
falktxhey rncbc15:40
rncbcfalktx: ola15:40
falktxrncbc: small thing in qtractor. your lv2 barBeats time position is wrong by 1 value15:40
falktxrncbc: see http://lv2plug.in/ns/ext/time/#barBeat "from 0 to beatsPerBar"15:41
rgareusrncbc: hiho15:41
falktxrncbc: but qtractor starts that value as 1, not 015:41
rncbcfalktx: bars and beats are always base-115:41
falktxlet me make a screenshot showing/proving this15:42
rgareusdoes anyone know what range  units:degree intends  Grad, Rad or Deg?15:42
rncbcrgareus: feeling great with setBfree :)15:42
rgareusrncbc: cool. I'm glad it keep the vibe.15:43
rgareusrncbc: does it work with qtractor OOTB?15:44
rncbcrgareus: but onder if im working it as rly intended, i mean on qtractor15:44
falktxrncbc: here http://i.imgur.com/Rxe4bhr.png15:44
falktxrncbc: right plugin ui is from qtractor. left is from jalv15:44
falktxrncbc: on qtractor the bar shows 2, on jalv it shows 115:45
rncbcrgareus: yes, but question is: is it supposed to work as a chain?15:45
rgareusrncbc: 2 setBfree's chained? no.    Keyboard [with motorized drawbars]  -> setBfree -> keyboard [drawbar motors]15:46
rncbcrgareus: i mean, dsp first then the other fx-plugins, including the final awesome leslie plugin ui?15:46
rgareusrncbc: the idea is that if you load a preset or midi-program, the drawbars move to the position.15:47
rgareusrncbc: the b_synth itself includes all effects15:47
rgareusthe tube, reverb and leslie are all included (to be able to control them with presets just like the real organ)15:48
rncbcrgareus: that's the tricky part of my question, qtractor may access the leslie w/e gui plugin alright, but it doesn't always get effect15:49
rncbcrgareus: i mean the lv2 preset15:49
rncbcrgareus: otherwise i'm having a hammond party all the way ;)15:51
rgareusmmh are you taking about the separate b_whirl.lv2  (not the organ itself)?15:51
rncbcrgareus: what u mean separate?15:52
rncbcrgareus: dsp first (no gui) than lesli (the rotating gui)15:52
rncbcleslie*15:53
rgareusthere are 4 LV2 plugins.    b_synth.lv2  All in one  the organ + amp + reverb + leslie15:53
rgareusb_whirl.lv2  separate leslie - e.g for playing guitar through a leslie15:53
rncbcrgareus: the laslie lv2 presets doesn't always work. may is my fault, i dunno15:53
rgareusmmh.  try    jalv.gtk http://gareus.org/oss/lv2/b_whirl#extended    or lv2info on it15:54
rncbcrgareus: and what i mean not working is about not having any evidence that the sound is any different.15:55
rgareusmaybe you have an old version in /usr/lib/lv2 and a new in /usr/local15:55
rncbcrgareus: and somewhat a third time it works. bummer15:55
rgareusaah. they don't sound different, really.  just the speed is different.15:56
rncbcrgareus: aha. yep i can see the knobs in stock gemneric moving... that must be it15:57
rgareusI found 2 different sources  how fast the horn and drum should spin and created the presets to check that out.15:57
rncbcgeneric*15:57
rgareusit's a ui#X11UI   that should just work with qtractor, does it no?15:57
rncbcrgareus: it works np.15:58
rgareusI'm just tweaking the port-names to make the generic UI a bit more usable.15:59
rncbcrgareus: question is/was about the stock leslie lv2 presets15:59
rgareusrncbc: I should probably remove them.15:59
rgareusthey only cover a subset: the RPM values15:59

rncbcfalktx: is that 1|1|0 from the vst and 2|1|0 from the lv2?16:01
falktxrncbc: let me try...16:01
rncbcfalktx: try also hit "play" :)16:02
falktxhmm, qtractor doesn't set transient window hints :(16:02
rncbcfalktx: wha?16:03
falktxthe external ui doesn't set the parent (transient) window id16:03
falktxanyway, same thing with vst / lv2 in qtractor16:04
falktxrncbc: vst has time right, lv2 has +116:04
rncbcfalktx:  ok. ill investigate. what's that transient window thing all about?16:05
falktxsomething for later16:05

rncbcfalktx: in think ive found the mistake... you seem to honor LV2_TIME__barBeat calculations, and ignore LV2_TIME__bar and LV2_TIME__beat ones17:21
falktxrncbc: I use LV2_TIME__bar, but not LV2_TIME__beat17:23
rncbcqtractor gets its LV2_TIME__bar = jack_position_t.bar (no point up nor down)17:27
rncbcfalktx: thats interesting because vst gets exactly the same information, but get it right (not off by 1)17:29
falktxthat's because you need to add -1 in there somewhere17:31
rncbcfalktx: lets see...17:32
falktxhttps://sourceforge.net/p/qtractor/code/ci/master/tree/src/qtractorLv2Plugin.cpp#l356517:32
falktxlv2_atom_forge_long(forge, long(time_bar.value));17:33
falktxthat seems to be it17:33
rncbcfalktx: and? https://sourceforge.net/p/qtractor/code/ci/master/tree/src/qtractorLv2Plugin.cpp#l351717:34
falktxI guess so17:34
falktxI haven't tested it17:35
rncbcfalktx: letmesee what vst does...17:36
falktxvst has ppqPos, which is a different beast17:37
rncbcfalktx: ohya17:37
rncbccould it be that it suffices a --bar ?17:38
rncbcat least i matches bar numbers17:40
