I could use some advice!

I got my two Mackie Onyx Firewire mixers set up with jack, using freebob. I think I may need to tweak the settings, because:

In Ardour, when I record, the recording sounds clean, but there is a short delay upon playback so that new material is slightly behind by a second or so. This happens for everything I record. I had increased the latency in the jack settings because stuff kept dropping out on record. These are the jack settings I used in qjackctl:

Server: jackd
Parameters: realtime
Priority: default
Frames/period: 2048
Sample rate (I don't want to change this!) 48000
Periods/buffer: 6
Port max: 256
Timeout: 500
Interface: default
Audio: duplex
Input latency: default
out latency: default
driver: freebob, of course

Latency comes out to 256 ms, something that seems to work alright in Windows, and which is about what the Mackies set themselves to when I use the Windows Mackie Onyx control panel to set the sample rate to 48k.

I would sure appreciate any advice.

I'm trying to emerge and run Psychosynth. If I use the psynth3d flag, version 9999 complains that ogre does not support the cegui use flag, even though ogre and cegui emerge without a problem. Plus, psynth3d requires cegui. I can compile Psychosynth without psynth3d, but then it doesn't run.

Without 3d, running psynth gives:

Please update the LMMS live ebuild. All live ebuilds of SourceForge hosted projects won't work anymore. For LMMS, EGIT_REPO_URI must now be "git://lmms.git.sourceforge.net/gitroot/lmms/lmms".

Haha, beat you to it by a few seconds :lol:

Thanks for the tip on LMMS - I'll modify the ebuild accordingly.

Ant_P and RealNC, thanks. That solved the LMMS problem.

Portage now has stk-4.3.1. Perhaps now this can be removed from the overlay? (It doesn't build anyway here; Portage applies a patch to fix it.)

I can't emerge media-plugins/azr3-lv2-9999.

If anyone's interested, I noticed a few things in lmms git the ebuild didn't cover so I tweaked it a bit.

Is LMMS known to have issues with jack? Whenever I start LMMS after starting jack, I get "LMMS was just kicked by jack" warnings and jack shuts down.

I can reproduce that error message. I'm pretty sure it worked with 0.3.x at some point though, maybe they're in the middle of rewriting it?

I'll try a 3.x version and see what happens.

Something to do with jackmidi, it says. What should I do to fix it?

LMMS live ebuild won't work anymore if you have "--as-needed" in LDFLAGS. I fixed the issue and submitted the patch upstream but there's no response yet.

If anyone needs it, the patch is:

What happened to kmiditracker? The src_uri is wrong - in fact the domain no longer exists and I can't seem to find the source any more.

EGIT_REPO_URI in lmms-9999-r1 is wrong again. Why did it get changed back (and of course it stopped working again because of this)?

Btw, the "--as-needed" patch was pushed upstream, so no more problems with that one.

Edit:
Also, please remove "ChangeLog" from DOCS, since that file has been not updated for a long time now and simply renamed to "ChangeLog.old" and this breaks the emerge. Change logs are now only provides by Git, so it doesn't make sense to include it in DOCS.

Is this bugtracker for the pro-audio overlay still relevant?

I see some bugs reported in the last time, but most of them stay in the "assigned" status without further actions. The last resolved issue dates back to August 2007.

If not, wht is the official way for a bug report in the pro audio overlay?

Hi all....

I'm quite new with gentoo but really like it so far, I like to use it as a digital audio workstation to record an modify samples and to bring these samples together in LMMS.
I've setup a nice DAW using the gentoo handbook and http://proaudio.tuxfamily.org/ 's wiki and howto's, all working fine exept for the use of midi devices.

when I start qjackctl I get the error

peertje888 · n00b Joined: 24 Jan 2009 Posts: 9

That /dev/snd/seq is not available can be a driver issue, which can be a kernel issue. Did you configure the kernel yourself? If so, check if you have SND_MPU401_UART.

Location:
-> Device Drivers
-> Sound card support (SOUND [=y])
-> Advanced Linux Sound Architecture (SND [=y])
-> Generic sound devices (SND_DRIVERS [=y])

If not you can select it as module (press M in 'make menuconfig') and do a 'make modules modules_install'
After that load the module with modprobe, 'modprobe snd-mpu401'.

Good luck

At first I used 'genkernel menuconfig' to compile the kernel with realtime support.

I've re-compiled the modules now, all went fine but still no alsa-seqencer available.
