[gentoo-user] Zynaddsubfx connected to Rosegarden WITHOUT Jack?

[meino.cramer]

Hi,

 may be this is a RDQ(tm) (real dumb question), but....

 Is it possible to connect rosegarden and ZynAddSubFX
 without using jack ???

 Thank you very much for any help in advance!
 Best regards,
 mcc

Hi Michael,

thank you for your info ! :)

What do I need for a midi connection (sorry, I am 
at the very beginning of exploring these kind of
tools and jack is everywhere... ;) )

Best regards,

do you have midi-ports in your soundcard? In some cases they are implemented 
as 5-pol Din plugs (MIDI-standard plugs), in other cases they are implemented 
via the gameport. Most built-in soundhardware has none.
If you have those ports, the most simple (but not best) solution is to connect 
midi in with midi out, have rosegarden play through midi out and the synth 
listen to midi in.
Afaik(!) alsa has virtual midi-ports, you can use, if you have no hw ports 
(and which would be more elegant to use), but I have no experience with them.
May I ask, why you don't want to use jack? I use it for everything in my 
studio and I am very happy with it. There's a reason jack is everywhere in 
this area :)

Re: [gentoo-user] Zynaddsubfx connected to Rosegarden WITHOUT Jack?

[meino.cramer]

Hi Michael,

I had * experiments with jack and nothing works...

Sometimes there was no connection at all, sometimes after a
short time rosegarden crashes and/or reports taht the connection
has gone, and so on....

May be I has simply combined the wrong things...

I have no midi hardware in the sense of keyboards, external
synths and such.

What I want is to set up a melody in rosegarden and to play
it via Zynaddsubfx.
A midi step sequencer (not sure if this this correct terminus
technicus, though) were also fine...

Any ideas?

best regards,
mcc

If this will become too OT simply use my PM :)

this is strange. It simply works for me (tm).

What versions did you try? (jackd, rosegarden...)

I see.

That's what I was thinking :)

I think, aconnect (part of media-sound/alsa-utils) is the tool you want to 
try.
Start both rosegarden and zynaddsubfx, then use aconnect -lio to see, what in- 
and out-ports were created on your system. After that use aconnect to connect 
the rosegarden out-port with the zynaddsubfx in-port.
http://alsa.opensrc.org/Aconnect has some details.
I never tried this for myself, so I have no practical experience with it.

Re: [gentoo-user] Zynaddsubfx connected to Rosegarden WITHOUT Jack?

[meino.cramer]

Hi Michael,

Thank you for your help ! :)

Here are the versions:
media-sound/rosegarden 11.02
media-sound/zynaddsubfx 2.4.1
media-sound/jack-audio-connection-kit 0.118.0

I did a aconnect -lio, which says:

client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
	Connecting To: 15:0, 128:0
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 28: 'Virtual Raw MIDI 3-0' [type=kernel]
    0 'VirMIDI 3-0     '
	Connecting To: 128:0
	Connected From: 128:3
client 29: 'Virtual Raw MIDI 3-1' [type=kernel]
    0 'VirMIDI 3-1     '
client 30: 'Virtual Raw MIDI 3-2' [type=kernel]
    0 'VirMIDI 3-2     '
client 31: 'Virtual Raw MIDI 3-3' [type=kernel]
    0 'VirMIDI 3-3     '
client 128: 'rosegarden' [type=user]
    0 'record in       '
	Connected From: 0:1, 28:0
    1 'sync out        '
    2 'external controller'
    3 'out 1 - General MIDI Device'
	Connecting To: 28:0


Then I started rosegarden, which - as expereinced before - pops up
a dialog, saying:

    The JACK Audio subsystem has stopped Rosegarden from processing audio,
    probably because of a processing overload.  An attempt to restart the
    audio service has been made, but some problems may remain.  Quitting
    other running applications may improve Rosegarden's performance.

(no jackd was running)

When clicking [OK] the dialog disappears only to take a very very short
rest an return again and again and again....

In one of these short tiemes of peace and slumber I open the
preference dialog and switched off jackd transport, quit rosegarden
and start it again only to play another fresh match between me and
this damned dialog... ;-/

How can I prevent to scratch my skin by the roses of this garden over
and over again.....?

Best regards,
mcc

looks ok to me. No idea, why it doesn't work for you.

Looks like rosegarden cannot work with pure alsa. I did not know this.
There's seq24 in portage, which seems to be a step sequencer that works 
without jack. You could try this one instead of rosegarden. I don't know 
anything about it though.

> How can I prevent to scratch my skin by the roses of this garden over
> and over again.....?

We could try to solve your problems with jack :)
I recommend qjackctl for jack-server handling.
How do you start it? What use-flags are set for it?
Another option is to try the versions from the pro-audio overlay (that's what 
I use for rosegarden, jack, ardour and some other audio related stuff).
Did you try other synths with jack and rosegarden? Maybe there's a bug in 
zynaddsubfx. You could try eg hydrogen to test this.

Re: [gentoo-user] Zynaddsubfx connected to Rosegarden WITHOUT Jack?

[meino.cramer]

Hi Michael,

 I will try (again) to be a friend of Jack (NOT "Daniels" ;) )...

 What I dont understand: Why all this hassle with Jack if Rosegarden
 has the ability to connect directly to Zynaddsubfx without any
 other gadget (see Studio->Manage Midi Devices, start Zynaddsubfx
 first)??? And if instructed so, why does this dialog still pops
 up and reminds me of a non existing Jack connection?

 I tried the masked version 11.06 of rosegarden: The same effect.

 I removed the "jack" USE-Flag from make.conf temporarily and
 rebuild rosegarden: No change.

 Ok, I will try jack...again...sigh.

 Best regards,
 mcc

Re: [gentoo-user] Zynaddsubfx connected to Rosegarden WITHOUT Jack?

afaict rosegarden relies on jack for it's audio processing. If no jackd is 
running this window pops up.

I sort of expected this. See above.

There are some other sequencers in the pro-audio overlay.
http://svnweb.tuxfamily.org/filedetails.php?repname=proaudio/proaudio&path=%2Ftrunk%2Foverlays%2Fproaudio%2F00-
DETAILED-PACKAGES-LIST
has a list of all packages. You could search this page for midi sequencers and 
try to find one that does not depend on jack.
And as suggested before there's media-sound/seq24 in portage, that only needs 
alsa to talk to synths.
jackd is really cool, if you are doing audio work. For MIDI stuff only, it adds 
nothing to pure alsa afaik.

Hi Peter

Following the above and finally starting jackd be hand (parameters
taken from the doc you mentioned) to see, what locks qjckctrl hard,
when starting rosegarden, gives the following output.

Is it possible, the jack goes crazy when seeing six cores running
in 64bit mode???

unlikely. My machine has 4 cores in 64bit mode and all works.

As Michael mentions (in his reply to this mail), it works for him so it
should work for you unless your configs (kernel + possible USE flags).
Perhaps you can compare? But, have you tried starting jackd from
qjackctl, as this mentions?:
https://bbs.archlinux.org/viewtopic.php?id=18451

Also, did you read through the entire howto?:
http://en.gentoo-wiki.com/wiki/JACK
There seems to be a few steps you need to take before installing
jack-audio-connection-kit (kernel configs etc.).

Perhaps you should follow this advice as well (after jackd is working
for you)...

Well, jackd is obviously waiting for something (I have no idea what).
Have you tried to run it without the -R (realtime) switch? Since I'm not
using jack I'm probably not much of help...

[gentoo-user] Rosegarden works???

[luis jure]

rosegarden works for you at all? wow, that's great.

i'm on ~amd64, and i haven't been able to make rosegaren work for a long
time. i searched the web and i found people describing the same problem
that i have on gentoo: if i type rosegarden on a terminal absolutely
nothing happens. the application doesn't launch, there are no messages on
the terminal, nothing. i just have to control-C after a while. 

i downgraded to different version, always with the same result.

i read that this is apparently related to problems with qt4.7. 

what versions of rosegarden and qt do you have working?


best,

lj

I don't use rosegarden, but I noticed you didn't try 'strace'. You
might want to add that to your troubleshooting toolset. It can be
handy for figuring out what's going on.

i.e. "strace rosegarden"

who said i didn't? :-)

yes, i did try strace, but i'm not a programmer, just a composer, so i
can't interpret the output. in these cases i can only google the results,
to see if i find something helpful (or ask here...).

strace rosegarden gets stuck at this:

futex(0x319b2cc, FUTEX_WAIT_PRIVATE, 1, NULL

googling this i found a page where it mentions that the problem might be
related to qt4.7:

comment#3 talks about jack. Is jack up and running, when you try to start 
rosegarden?

yes, i tried both with and without jack running. i don't use jack normally
and don't know much about it, i just tried starting jackd -d alsa and jackd
-R -d alsa. can't see any change when trying to start rosegarden.

i don't have a clue, really. it seems that i'm not the only one having
this problem, but on the other hand it works for the rest and no-one
seems to have an idea how to detect what could be the cause of this. i
tried all the usual suspects already.

thanks for your attention!

What version of jack are you using?
Could you post its output when starting?
I'm looking for differences to my own setup. There must be some reason why it 
works for me, but doesn't for you.

i have jack-audio-connection-kit-1.9.7 installed. but i think this
shouldn't be the problem, because at least in the past jack was needed
only if you were going to use audio in rosegarden. the program itself
should launch even if jack is not running. or am i wrong? could you try
starting rosegarden from the terminal without jack? does it start?

vielen dank für deine hilfe!

I am still using jack1 (1.9.7 is jack2), because I had nothing but troubles 
with jack2.

rosegarden starts jack for me, if it is not running already.
Is the dbus-use-flag enabled for your jack?
Afaik the startup procedure for jack2 is different from jack1's, at least if 
that flag is enabled. Could well be, rosegarden has problems with that.
But because of my negative experience with jack2, I would try downgrading jack 
to 0.121.2 or something like that and try again.

no, it wasn't.

i did that, but no joy...

anyway, i'm not convinced the problem is with jack, i think it must be
something before that. rosegarden doesn't send any messages to the
terminal or anything, just stays there...

i tried 11-02 from the pro-audio overlay, with no luck. i have qt-4.7.3
currently installed. i don't think the difference with 4.7.2 might be
relevant, i've been having this problem for quite some time.
