Re: [LAU] MIDI sysex over Firewire - not supported by Jack MIDI?

Thanks for that Ralf, I have wondered in the past if there's a proper way to use these things - how's this? >Date: Thu, 11 Dec 2014 18:39:38 +0100 >From: Clemens Ladisch <clemens(a)ladisch.de> >Ralf Mardorf wrote: >> On Thu, 11 Dec 2014 12:04:09 +0000, oli_kester wrote: >>> On Wed, 10 Dec 2014 20:10:40 +0000 Clemens Ladisch >> >>>> In kernel 3.16 or later, the snd-bebob kernel driver should work. >> >>> I'm not sure what you mean by this >>> >>> do you mean switch to a different kernel entirely? > >Yes; you would have to upgrade your kernel >(with whatever mechanism your distribution uses for this). > >> Kernel's >= 3.16 provide this kernel module, you likely need to load >> it, before you can use it. > >It would be loaded automatically. ...and I now have a new shiny kernel - and a result: The FA101 has MIDI I/O showing in JACK MIDI, which is superb! Thanks to both of you - I'd never have thought of touching the kernel to solve these problems. I went to do my sysex recording just now, and unfortunately I can't get these new "EDIROL FA-101 MIDI 1" ports to connect to anything. This isn't something I've experienced before - you can Alt-C to connect like anything else, but no connection line appears no matter how many times I try. I've restarted Jack to no avail. Any more suggestions? cheers, Oliver

Hey hey, I have two M-Audio Delta 1010 soundcards. Currently my driver is built into the kernel. Can I rely on the two cards not being swapped after reboots or can I fix it, even though the driver is built into the kernel? A pointer to meaningful documentation on that point will suffice. Thank you! Ta-ta ---- Ffanci * Internet: https://freeshell.de/~silvain Twitter: http://twitter.com/ffanci_silvain

Signal generation with Jaaa?

by Mac

I loaded Jaaa 0.8.4. It appears to only have a analyze mde. Is there a switch to get it to be a signal generator as well. And the user interface doesn't have the output section as shown on the kokkinizita web site. Regards, Mac

Re: [LAU] How to use hdspmixer - Was: RME HDSPe AIO, hdsploader compulsory ?

by francois juigner

Hi Ralf, Things have improved a lot: I'm able to use all my wanted outputs through hdspmixer : phones, SPDIF,AES and analog all work fine. Now i'm left with the task to introduce brutefir in the process. My guess is that it is another story !!! Final word for now : RME HDSPe Aio is well recognized in Alsa to-date, the powerful (thank you Thomas) but not straightforward hdspmixer lacks a good "how to" file somewhere... Thank you all for your help, I will now dig into the bash scripts ! Francois -- francois juigner <francois.juigner(a)bluewin.ch>

How to use hdspmixer - Was: RME HDSPe AIO, hdsploader compulsory ?

Correct, it's impossible to change this. In my demo file the submix view is disabled. Check the submix view and after that you can select the "label" and then use the faders for the submix. It should work for analog, phones and ADAT 1+2, IIRC for S/PDIF too. I never tested AES/EBU. It doesn't work for ADAT 3 to 8 on my machine. Please, a few mails off-list are ok, but when sending a request to a mailing list, it's better to provide the way to solve the issue to the list too. -- "Pull a Homer -- to succeed despite idiocy." - The Simpsons

Re: [LAU] RME HDSPe AIO, hdsploader compulsory ?

by francois bluewin

Hi Harry, Hi Ralf, Thank you for the fast answers. Harry, in fact you did not quite answer question 1 : do I have to use hdsploader ? Put it another way, would the card be recognized if the firmware is not ok? This firmware question is not clear for me : I fear to corrupt the card's windows firmware if I run hdsploader. Maybe that's completely wrong... I agree that using amixer seems to be a horrible way to work, but I could not manage to get anything out of hdspmixer... There is no way to change the routes it loads by default ! clicking on the playback labels doesn't allow to check or uncheck existing boxes. This is why I wonder if there isn't anything wrong with my setup, namely : would the use of hdsploader change hdspmixer's behaviour ?

[ANNOUNCE] jack_autoconnect

by Jannis Achstetter

Hi list, I recently decided to try the following setup: mpd is running on my NAS machine with jack audio outputs and ympd as web interface. The jack server uses the dummy backend but has the netmanager loaded. The problem is that mpd sometimes deletes its jack ports and created a new pair. And since the number and names of the connected net slaves varies, I thought a classic session manager might not fit (admitting that I didn't really try it). So I created a small program that registers as slave without ports but watches for new port registrations. If a pair of out- and input ports matches their regular expressions specified on the command line, they are connected. I used Qt to solve the problem that ports cannot be connected in the same thread that the notification-callback is executed. Using the QueuedConnection, the SLOT (reaction to a SIGNAL event) is executed in the receiver's thread. To solve the challenge I'm using this command now: jack_autoconnect "Music Player Daemon:left" ".*:to_slave_1" "Music Player Daemon:right" ".*:to_slave_2" The system is working pretty well. The music and playlists can be controlled from any device with webbrowser and multiple playout machines connect via NetJack to the NAS. And the synchronization between all of them is just perfect! The code is on github: https://github.com/kripton/jack_autoconnect Comments are welcome :D A big "Thank you!" too everyone who makes all of this possible! Best regards, Jannis
