I have not tried that, I was sure there would be a 64 bit version real
soon :-) I guess a test could be made of whether the 32 bit version will
install and pull in the appropriate 32 bit libraries. Some libraries on
x86_64 have both versions but I don't know which ones.

[back from LAC2008 - it was great as usual]

Wow. Sorry about that. I have not seen that many problems in my laptop.
I see there's a newer version of Ingo's rt patch, maybe that will fix
some of the problems? I'll try to do a build tomorrow.

Compiling Planet CCRMA kernel for Macbook Pro


I've had rather mixed experiences with the recent Planet CCRMA  
kernels (on Fedora 7) on my Macbook Pro, so I was considering  
recompiling my own to incorporate things like acpi and the macintel  
patches. Has anyone on this list done this and be willing to guide me  
in the process? I'm comfortable with command line utilities, but it  
would be my first attempt at doing something like this.

Qjackctl connection saver (patchbay)

Hi all,

When I use qjackctl I never use the patchbay function because the most important things never work with it.

My connection saver does not seem to save connections between my control surface and freewheeling, and I still need to manually connect other things. The patchbay definitions load fine, and I get no error messages.

I want to use Linux live but I'm scared if I crash during performance, my ability to recover quickly isn't there. To this end, I'm wondering if anyone has any thoughts on this?




Thanks,
Nicholas

qjackctl patchbay won't (re)start applications but will take care of the
(re)connections alright.

it doesn't work ootb either. you need to understand the patchbay model and
setup the patchbay definition with some care. just don't assume that the
snapshot that you get when you hit the "new" button is of any use. it
isn't. it helps in doing and refining things but it does not work as is.
unless your connections layout is strictly simple (eg. only stereo audio)

i'm the one to blame, sure, for the lack of documentation. however there's
this attempt of explaining things a little bit:

Re: Qjackctl connection saver (patchbay)

ahhh, I am indeed using the snapshot feature.. I guess I'll dig deeper and figure it out. good to know it can be done.

i guess I should learn how to do a bash script to restart apps

Re: Qjackctl connection saver (patchbay)

Would the LADCCA/LASH session handler be of any use in this situation?  I believe its purpose is to store/restore ALSA and JACK client connections (audio and sequencer).

problem with that approach is that not all applications are lash
aware--programs must be coded as lash clients for just that

qjackctl patchbay just fills half of the need, that is (re)conections and
not (re)starting jack/alsa-seq client applications

Qjackctl connection saver (patchbay)

Ah, I see.  So a simple script (to start up clients) combined with the qjackctl patchbay would be the way to
recover quickly, yes?
