lv2-saverestore

23 February, 2010 - 23:16 — dazgard

hi there,

i can't get Linuxsampler lv2 version to keep it state after save/close in qtractor.
i tested qtractor last version and svn : same error
Linuxsampler's dev said LS is using the lv2-saverestore extension.
Is it because Qtractor does not support this extension, i can't save/restore LS state in Qtractor ?

You're correct, Qtractor doesn't support the saverestore extension, yet.

I'll have a look at it soon.

Byee

im glad to hear this.
thx man ;)

Today's SVN trunk already has it for the grabs (qtractor-0.4.5.1529+).

Don't be shy and please tell whether it works for you, specially re. LinuxSampler LV2 plug-in. It does seem to work for me ;)

Enjoy

hi Rui,

i gave the last svn version a try, and linuxsmpler lv2 is working fine here.
man that's really cool. qtractor is becoming something really interesting, thx to you.
Brother, lv2-saverestore mission for qtractor is a success !!!
see ya ;)

Awesome!

May you disclose a little bit about the ways you're using the linuxsampler lv2 plugin? Do you use it on a MIDI track (single channel) or bus (multi-channel/timbral)? How many plug-in instances and/or sampler channels are you using effectively? Does the lv2-saverestore extension work without clashing on all scenarios? Which linuxsampler front-end do you use for setting up sampler channels? Qsampler, Jsampler (or is it raw lscp via telnet/netcat like real men do:) ?

hi Rui

Do you use it on a MIDI track ?
- Yes, everything is working just fine

or bus (multi-channel/timbral)?
- Yes i tried this configuration too, no problems to report, i just have to figure out how to route the plugin audio and to add FX on each instruments. Maybe the simplest way would be to use one sampler instance for one track...

How many plug-in instances and/or sampler channels are you using effectively?
- not that much : 5 or 6

Which linuxsampler front-end do you use for setting up sampler channels?
- Jsampler, sometimes Qsampler

if you have other question just go ahead and ask :)

thx man

From which version of Linuxsampler is this supported?

You add linuxsampler as plugin, but how do you add an sample? Or do you start linuxsampler outside qtractor first?

LinuxSampler 1.0.0 comes ready in both LV2 and DSSI plugin forms. Just add one instance to a MIDI track or bus and linuxsampler server will get automatically started behind the scenes. Then you can use your preferred LS front-end, either Qsampler or Jsampler to add and manage sampler channels, as usual.

nb. each LS plugin is seen as one device instance of the PLUGIN device type which gets in use by each sampler channel (this is all LSCP parlance:). You don't get the usual/integrated GUI for each plugin instance. You use a regular LS front-end instead to manage all sampler channel instances, including the ones which might not be inserted as plugins at all, ie. the regular stand-alone LS use cases on device types JACK, ALSA, etc. Yep, kitchen-sink approach :))

Just try :)

Cheers

- yes, of course

What is the benefit of using it as plugin instead of standalone app?
- the host (eg. qtractor) will take care of saving and restoring session state seamlessly; after all that is the whole purpose of the OP ;)

Cheers

Hi,

I use linuxsampler as a DSSI plugin in qtractor, I load and select the instruments through QSampler, which works great. However, I have difficulty saving and restoring the session. If I quit and reload qtractor session, the samples from plugins are not loaded. I'm not sure how this is supposed to work. I tried saving a session in QSampler and restoring it atfer loading qtractor session, but that doesn't seem to work (gives a lot of errors in Qsampler output). So the only solution right now seems to be to load instruments manually after I open qtractor session. Am I missing something, perhaps I should try with LV2 plugins?

thanks,
Marko

Can't really say how linuxsampler-dssi works wrt. saving/restoring its state. From your post I can read that it doesn't and you're welcome to ask the linuxsampler-dssi developers how they intended that to work, if at all.

I guess the linuxsampler-dssi plugin should save/restore its state through the DSSI "configure" interface as it's the official protocol for just that. Qtractor would handle it as with any other DSSI plugin. However, it doesn't seem to work in that way. I'll have to investigate this case in particular and try and tell you later what's actually missing.

Meanwhile, the LV2 plugin seems to work just fine in that regard.

Cheers

hi Rui,

im trying to get the lv2 linuxsampler to accept more than 2 channels with no success.
I am adding one instance per track. so that is one linuxsampler instance and one audio and midiport pair per track.
qtractor will keep on crashing when trying to add more than 2 tracks with an lv2 instance of Linuxsampler.
if you need more info, just ask :)

I'm sure it needs more info, yes, specially about the actual crash circumstances. Stacktraces are always due but you'll need to build it for debugging (./configure --enable-debug).

Re. MIDI channel assignment, I'm afraid you'll need to give it a tweak also on the linuxsampler side (qsampler?), that is, when you add a new MIDI track in qtractor it will increment MIDI channel accordingly, which is just convenience, but event though you add another linuxsampler plugin instance in there, it will keep as set to MIDI channel 1 (one) as default. You'll certainly have to travel to your preferred frontend to let the new sampler channel match that newer MIDI channel. That's it. or am I missing the point?

hi Rui,

MIDI channels are OK. qtractor midi track 1 and 2 have Channel 1 and 2 and the last midi track (the third) is on channel 3. inserting an other lv2 linuxsampler just make qtractor crash.

here are some more information about the crash :

Ay caramba!

Does it always crash on inserting the forth (4th) instance?

I just can't reproduce that. Here I've managed to as plenty as 7 instances, or more.

However, sudden and rather randomly, it was LinuxSampler plugin code that started to bitch itself about lacking of resources to create another thread or something like that. I believe that's exactly the same as I can read from your crash dump above. It sometimes does crash or just hangs in that, but definitely it's a linuxsampler issue, somehow.

Please, report it also to bugs.linuxsampler.org.

Cheers

hi man,
yeah it ALWAYS crash on the third (3rd) instance, no matter what :)
when using Linuxsampler alone, i can add as many channel i want.
tonight I'll give linuxsampler standalone an other try with on port pair per channel to see what happen
and by the way, which LS version are you using ?
I am using the cvs one, maybe this is the cause...dunno

22 March, 2010 - 11:07 — dazgard

yeah, i gave LS lv2 and qtractor an other try, on an other system (an other linuxmint).
And you know what ? man... everything is working just fine. i must review my system to see what's going on

thx for the help man ;)

Guys, what is bus (multi-channel/timbral)? What do you mean by that?

In Qtractor parlance, a MIDI track holds one single addressable MIDI channel (1-16), usually assigned to drive one and only instrument or voicing.

A MIDI bus is a virtual mix-down of all the assigned MIDI track streams, so that it merges all 16 MIDI channels in one MIDI data stream. This is how a MIDI bus can drive a multi-timbral sound module generator which can be a plugin, an internal or external synth or sampler, where each MIDI channel drives one distinct instrument voicing (or instrument patch, preset whatever).

Fluidsynth and Linuxsampler are examples of multi-timbral soft-synths/samplers. In opposition, Phasex are one example among many, of a mono-timbral soft-synth as each instance is addressed by one or any MIDI channel (the latter case means it functions in "omni mode" as in MIDI standard).

Most instrument plugins are mono-timbral and thus only make sense inserted on a MIDI track (1 channel). Multi-timbral instrument plugins are better used when inserted in a MIDI bus (16 channels).

I sort of think I know what you mean. In other words, if someone would show me an example project I would me most grateful.
