and why is that a problem at all?

i must say it's been like so since day 0 in qtractor model; it has been 
like so for external soft- and hard -instruments, following the GM/GS/XG 
standard all over; plug-ins are no different either, even though you can 
insert a multi-timbral plug-in on a midi output bus, MIDI tracks volume 
and pan will converge to it on respective MIDI channel basis, so there's 
no escape from that.

otoh. the problem i see is often one of hard-wiring these MIDI 
controllers (cc#7, cc#10) directly to an internal instrument state 
parameters or control ports, whatever--in my (fairy tales) book, 
hard-wired MIDI CC's *should* "modulate" the DSP model variables, and 
never override directly fundamental state model variables.

eg. considering a state_value in the normalized range [0, 1] and 
midi_value in [0, 127] 7bit range, then the  effective dsp_value 
should be:	dsp_value = state_value * midi_value / 127;

thinking of which, you may probably know that doing this MIDI controller 
1:1 functional mapping to a plug-ins internal state is considered 
"serious felony" by the LV2 police, don't you? ;)

As a compromise Qtractor's override behaviour could made to be toggled,
ideally per track, with the default "on". Experts who know what they do
then can change it to "off".

Hi,

the condition should be a condition a user explicitly set up, IOW, if you  
scroll to a sequencer position, the sequencer should set all parameters to  
the values that were chosen before or at this position. A parameter that  
wasn't explicitly set, should be kept at the last value that was used.  
This is how all other sequencers work, since the 1980s, AFAIK Qtractor is  
the only sequencer with this odd behavior. Will, even your above  
recommendation is wrong. A sequencer should do what the musician  
recorded/edited and only set values regarding to the song position. If  
nothing was recorded or edited, the sequencer isn't allow to set anything.  
There's one exception, but even for this exception a coder should be  
careful and not by default reset everything, it's a panic button, to get  
rid of hanging notes, but resetting e.g. pitch bend or modulation wheel  
not necessarily belongs to a panic reset.

Ralf

Yes, Yoshimi accepts most standard MIDI CCs

This is a real problem. Yoshimi state is a very complete setup and is intended
to restore it to *exactly* the condition it was saved at. If you are changing
anything at all after the state has been loaded you break Yoshimi's model.

I've had this discussion with other sequencer builders. While I can appreciate
the desire to put things in a known condition, it's my belief that any such
changes should only be made *before* a state or patch set load.

Hi,

a long time ago I already considered this being a bug and not a feature.  
Rui, you'll hopefully change your mind about this approach now. This  
"reset" at the start of a track, where a user not necessarily wants the  
sequencer to control CC vol and/or CC pan is a PITA. Just imagine the  
sequencer should get started, after a live improvisation and it should  
continue with the CC vol and/or CC pan were the improvisation without  
sequencer finished, then it's impossible to set wanted values for the  
track, unless you're a psychic. Even if you know the values, sometimes you  
simply use the controls of your external MIDI synthesizers, since they  
might be all in a rack and it's easier to select sounds and to mix while  
standing next to the rack. Some people dislike to repeat everything for  
the tracks, especially since nobody remembers the values that are aligned  
to e.g. 10 pan positions, while MIDI provides 128 steps.

Regards,
Ralf

qtractor does override each MIDI track/channel with those controllers 
--they're both handled as MIDI track/channels properties for that 
matter--upon session setup and anytime later, eventually whenever
MIDI connections changes.

Well, it's weird ; Sometimes, it does. I have sessions, here, that has

BUT sometimes, it can take some time to... I don't know stick? Before 
the track actually remembers.

So I would second, there may be a PB, but it is is not exactly that 
Qtractor does not save Yoshimi's state, because, well, sometimes (and in

[Qtractor-devel] LV2-Yoshimi state save/load

[Will G. <wil...@mu...>]

Yoshimi's state includes all volume & pan settings, but qtractor somehow
doesn't seem to restore these. It gets all the instruments in the correct parts
but with pan at centre and default volume. I don't know how it manages to do
that! Both Ardour and Muse get this right.

However,  qtractor *does* respond to in-file MIDI messages correctly.

[Qtractor-devel] [ANN] Qtractor 0.7.5 - The Hazy Photon is out!

[Rui N. C. <rn...@rn...>]

Hello everybody!

   Qtractor 0.7.5 (hazy photon) is out!

It comes with one top recommendation though: please update, at once, 
while it's hot! :)

Highlights for this dot/beta release:

* Overlapping clips cross-fade (NEW)
* MIDI Send/Return and Aux-Send insert plugins (NEW)
* Generic and custom track icons eye-candy (NEW)

Some other interesting points may be found in the blunt and misty 
change-log below.

And just in case you missed it before,

   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.

Change-log (since last tacky release):
- Beat unit divisor, aka. the denominator or lower numeral in the 
time-signature, have now a visible and practical effect over the 
time-line, even though the standard MIDI tempo(BPM) is always denoted in 
beats as quarter-notes (1/4, crotchet, seminima) per minute.
- Fixed an old hack on LV2 State Files abstract/relative file-path 
mapping when saving custom LV2 Presets (after a related issue on Fabla2, 
by Harry Van Haaren, thanks).
- Default PC-Keyboard shortcuts may now be erasable and re-assigned (cf. 
Help/Shortcuts...).
- New option on the audio/MIDI export dialog, on whether to add/import 
the exported result as brand new track(s).
- Introducing brand new track icons property.
- Old Dry/Wet Insert and Aux-send pseudo-plugin parameters are now split 
into separate Dry and Wet controls, what else could it possibly be? :)
- Brand new MIDI Insert and Aux-Send pseudo-plugins are now implemented 
with very similar semantics as the respective and existing audio 
counterparts.
- Implement LV2_STATE__loadDefaultState feature (after pull request by 
Hanspeter Portner aka. ventosus, thanks).
- Plug-ins search paths internal logic has been refactored; an 
alternative file-name based search is now in effect for LADSPA, DSSI and 
VST plug-ins, whenever not found on their original file-path locations 
saved in a previous session.
- Finally added this brand new menu Clip/Cross Fade command, aimed on 
setting fade-in/out ranges properly, just as far to (auto)cross-fade 
consecutive overlapping clips.

Rui, the coder of Qtractor is also responsible for QjackCtl. Perhaps
you should start with reading about QjackCtl.

What Linux distro are you using?

I can't say much about pluseaudio, however, to start with Linux audio

[Qtractor-devel] just a friendly developer

[ty a. <aa...@ci...>]

I am looking for tutorials on basically every line of code in QTractor. not
for me so much, but so that the general public and average end user can get
involved and start fixing bugs and submitting code to further the
development of qtractor.

I am also looking for tutorials on how to connect the following
applications to qtractor: Guitarix, rakkarrack, lmms, hydrogen, qsynth,
zynaddsubfx, yoshimi, etcetera and bristol

if you want, you coudl even consider incorporating similar software to
those into qtractor in an attempt to make qtractor on the same level as
ableton or something like that.

tutorials are great. And do I have to edit /etc//pulse/default.pa to get
sound? i forgot
some applications I have to.

oh yeah if you want to you can write synthesizers under qtractor like the
following it mighte be fun
Tb-303
tr-606 mc-909 march uds, lell uds, rokton uds(drum synths)
polivock, aelita(synths)
juno 6
juno 106
access virus B
and post tutorials on everything so that anyone can start designing and
coding their own soft synths.

you could even do some microphone DSP under qtractor like auto tune and
flange and stuff it might be fun.

and if you really want to you can emulate animal and industrial noises.
this is especially good for techo and electronica music because it makes
re4ally interesting music when you can throw in some animal noises too.

get creative search around the internet and see what you come up with and
do it!
oh yeah you can search for instruments too if you like.

but again these are just suggestions for fun and may help qtractor reach
its full potential.

[Qtractor-devel] [ANN] Qtractor 0.7.4 - The Tackiest Gluon released!

[Rui N. C. <rn...@rn...>]

Ahoy there!

   Qtractor 0.7.4 (the tackiest gluon) has been released!

Y'all know the drill...

   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.

Change-log:
- Eye-candy warning: muted/non-soloed tracks are now shaded over the 
main thumb-view.
- Faster and crispier VST plugin editor (GUI) idle cycles.
- Fixed all core processing when any plugin has more audio outputs than 
channels on a track/bus where it's inserted.
- Added one decimal digit to all percentage input spin-boxes on the MIDI 
Tools dialog.
- Added brand new and global option to disable the so called "catch-up" 
default behavior (cf. View/Controllers.../Sync).
- Fixed some track control issues related to MIDI Controllers generic 
mapping (cf. View/Controllers...).
- Try making Help/Shortcuts... dialog window modeless, as far as under 
MIDI Controller, Inputs/Outputs Connections window also gets accessible 
enough.
- Fixed some vertical scrolling and play-head line re-drawing glitches 
introduced by the recent unlimited slack to editing beyond current 
contents length on main tracks view.
- Added one decimal digit to the Pitch-shift spin-box on audio 
Clip/Edit... properties dialog window.
- Added application keywords to freedesktop.org's AppData.
- Fixed local keyboard shortcuts on the Files organizer widget actions 
and context-menu.
- Improved Mixer multi-row layout (patch by Holger Marzen aka. bluebell, 
thanks).
- Fixed the Ctrl+drag/cloning left of a clip when towards near the 
beginning of session.

indeed. this have been already fixed on git head master, currently 
v0.7.3.14+

apparently the renoise_redux_vst presents itself with a total of 24 
audio outputs and even though it defaults to have the first 2 active by 
default it seems to process and override all the remaining and 
superfluous other 22, which i find overkill (maybe it's only the demo 
that behaves like that, as to make sure it stains all the outputs with a 
bump of noise, periodically, who knows? :)

there's nothing i can or may say besides you could try and set the GUI 
refresh rate into less than 60fps; having it on 20fps is more than 
enough imho.

[Qtractor-devel] Qtractor 0.7.3 with Renoise Redux 1.0.1

[Nikita P <the...@gm...>]

Hello,

I've tried running Renoise Redux Demo
(http://www.renoise.com/products/redux) 64-bit Linux VST in Qtractor
and have noticed the following:
- there's no sound at all: the internal meters of Redux show activity,
but Qtractor meters show nothing and I hear nothing too.
- the UI is slow

When I tried running the plugin in Ardour 4.6.0 I got both sound and a
smooth UI straight out of the box.

What could be the problem?

hi Frank,

yes it's amn old i'm afraid. my best guess it's all about 
non-dummy-VST-scan and u-he Diva was/still is ill behaved on inventory scan.

if you're not trying to search for any VST shell sub-plugins in 
particular (eg. zebra2 et al.) you're better turning the dummy-VST-scan 
ON and search again.

hth.

[Qtractor-devel] Crash when switching plugin chooser window from LV2 to VST

[Frank N. <bea...@we...>]

Hi all, happy new year to the world,

I have encountered a (mostly reproducible) crash in qtractor, version 0.7.3.
Situation: I have a couple of LV2 and VST plugins on my system, with the VST
plugins (u-he's Linux ports of their instruments&effects - Diva, Hive etc; a
total of 13 plugins) installed in ~/.vst/ (just symlinks) resp. ~/.u-he/ (physical
locations of plugins).

Process to reproduce the crash:
- Start qjackctl/jackd.
- Start qtractor
- Track->New, type MIDI
- In Mixer window in the new track, right mouse button and "Add plugin"
- In plugin chooser, switch to "LV2" plugins, select and add (in my case) "Calf Organ" plugin
- Again, in mixer window in that track, right mouse button and "Add plugin" again
- In plugin chooser, switch to "VST" plugins
--> Boom:
*** Error in `qtractor': free(): invalid pointer: 0x00007f6ab3519c60 ***
Aborted

I rebuilt qtractor with --enable-debug and then ran it through gdb; below is
some extra output from that session.

The u-he plugins were taken from http://www.kvraudio.com/forum/viewtopic.php?f=31&t=424953,
and I have the most current version (build 3965) on my system.

Rui, did you (or anyone else) ever run across this?

I have noticed that if I remove some of the symlinks from ~/.vst, qtractor will
at some point not complain anymore (but on quitting it, I get a coredump); if I
continue to remove more plugins, at some point it will also behave fine on
quitting. Not sure if this is related to an individual VST plugin or their plain
amount that is getting scanned/interrogated by qtractor.


Greetings,
Frank ("new year resolutions: report more qtractor findings" :-)

[Qtractor-devel] [ANN] Qtractor 0.7.3 - A Tackier Gluon is out!

[Rui N. C. <rn...@rn...>]

Hello there and again,

This time getting ready for the NYE. Prepare to party, the countdown has 
begun... but first, let there be just one cheesier announcement ;o)

   Qtractor 0.7.3 (a tackier gluon) is released!

Everyone is strongly invited to upgrade. No excuses.

   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.

Change-log (since last cheesy release):
- Slight increase on the number of decimal digits for the plugin 
parameters while on the generic plugin properties dialog. Also applied 
to automation curve node value editing.
- Unlimited slack is now in effect on editing over and beyond the 
current session or clip contents length, on both the main tracks and 
MIDI clip editor (piano-roll) views.
- Ctrl+click and dragging the left or right edges of a clip will now 
make it spill over and replicate as many clip clones as it fits in the 
left or right horizontal extent.
- Added View/Note Type and Value Type command menus to the MIDI clip 
editor (aka. piano-roll) which opens the possibility for discrete 
shortcuts to switching views eg. Note Velocity and Controller views 
(after a kind request by yubatake, thanks).
- Fixed the conversion and/or override of MIDI clip offsets when moving 
and copy/pasting across tempo/time-signature changes.
- Fixed MIDI file track/channel duration estimator, which was giving 
quite wrong and way too short reads.
- Fixed a drag-and-drop bug over the main tracks view, when new tracks 
were being inserted at the top and not to the bottom as is normally 
indicated by the floating visual placeholder.
- Fixed LV2UI_Resize handle from extension_data(LV2_UI__resize), now 
passing LV2UI_Handle in first argument to ui_resize(), as found correct 
and needed for resizable/scaleable LV2 UI's, most specially to ssj71's 
so called Infamous Plugins, thanks.

but there is: hovering for awhile on an automation node does show its 
tooltip, curve name and value; of course it needs menu View/Tool Tips 
option turned on.

wow! that was so quick and overwhelming that i've missed the whole 
question :)

just a hunch: have you ever tried double-click on an automation node? ;)

hth.

[Qtractor-devel] Automation values

[Philip Y. <ph...@gn...>]

Hi! Just a quick one on automation

Ever since TYOQA, when I use it, it's usually because I played with a 
plugin control, and decided I wanted its value to go from A to, say B. 
Sometimes there are more than 2 values.
So I set said control to value A, and keep value B in my head. Then I 
create an automation curve for this control.
Now what I'm expecting at that point, is an infinite curve with one 
point on it, set at value A.
Even better for this point would be to be created not at the start to 
the song, but at the playhead's position. That would make 3 points. I 
hope I'm making sense.
Now depending on the plugin use, I get the curve, but with no actual 
point on it, and it is "set" at either minimum 0 value, or (seemingly) 
max value. The control's (current) A position is lost, oh well.

But hey, I can work too, I can still retrieve my values and set them.

But wait, that will be hard, because there is no indication of the value 
of the point, neither as tooltip, nor in the messages window, not even 
stderr.

None of this is blocking. Furthermore, I suspect that 1-getting & 
setting those values at those precise times may be impossible on 
Qtractor's end, depending of the plugins - please note that I (and my 
friends) tend to use exclusively LV2 plugins for those reasons - I'm 
just saying. Now I got to retrieve my values, and it can (probably will, 
it depends) be long and tedious, specially if the variations are small 
in between A and B (And C and X) and I spent a lot of time within the 
plugin setting them up. I had this PB many times and forgot to mention 
it. It can be a nightmare, what I do is I loop the part, then open the 
plugin, then watch the control move, then close the plugin, pause 
everything, adjust the curve points, rinse and repeat :) reminds me a 
bit of my tracker times when each value had to be manually entered as 
(hexa) text values :)

Phil

PS - My life in Qtractor is no longer the same since I know the 
shift-click trick. You know what would be cool? A continuous contextual 
status bar keyboard help (what, you don't have a CCSBKH? Sheesh ;)) like 
the one in Inkscape. If you decide to do it, I can help with filling in 
all the messages slots

1) automatic crossfades are not in the short term plan, sorry; note that 
you can have as many clips overlapping each other, no only two; you 
still have clip fade-in/out though, as Ralf already mentioned, only that 
they are not set automatically but discretely manual.

2) i know audio clip peak waveforms can become rough and ugly on extreme 
zoomed-in scenes--however that's not a top priority on my list, so sorry 
again.

let none of the above step you back from trying make it better and 
possibly contribute a patch ;)
