LinuxMusicians

Your question is a bit ambiguous - do you want to use 2 different soundcards on 2 different systems at the same time? I think this is quite difficult and requires use of netjack which I have no experience with. When using 2 soundcards there is the intrinsic problem of keeping the clocks synchronized...

I do not have this card but according to the ffado device page this device is fully supported - see http://www.ffado.org/?q=node/71. Also I'd recommend using a audio-oriented linux distribution rather than vanilla ubuntu. I've had good experience with dreamstudio (which is an audio-centric ubuntu ve...

I can only suggest some kind of sanity test - double check that you really have installed the packages on the non-working computer, use synaptic or other tool to confirm that the libraries/other files really exist on disk and that there are no conflicting versions (like files in both /usr/lib and /u...

Well this is sort of a tangential suggestion. You might consider trying AVLinux which does not have pulse at all with which I've been able to be very productive with Linux music applications. However, AVLinux is Debian-based so you cannot install kxstudio on it (at least I do not know how), except f...

I think you need to compile both libgig and linuxsampler from svn. I don't recall having to change any flags to enable SF2, SFZ support. (I compiled it in the past, so going from memory). By the way AVLinux5 and DreamStudio already have the SVN version of Linuxsampler installed so you get SF2,SFZ ou...

You need to run a2jmidid (http://home.gna.org/a2jmidid/) which provides a bridge between alsa midi (ALSA tab) and jack midi (MIDI tab). Start from the command line as "a2jmidid -e" to bridge all hardware midi sources. If you are using Qjackclt you can setup a2jmidid to start up when Jack i...

I need to check for xruns more carefully when these disconnects happen. Since they are infrequent and not reproducible its harder to study systematically. Obviously, increasing latency is always an option, but I do not really like to go above 10 msec for live playing. I tend to suspect that there is...

I often play keyboards using Pianoteq, linuxsampler and Yoshimi often at the same time. I do this with a latency setting of 5-10 ms since I'm playing live. I have the occasional problem that once and a while (e.g. after 30 minutes playing) one of these programs will disconnect from Jack and I have t...

Here's a fairly detailed article on the state of the realtime kernel:

I do not have any very good ideas except the obvious: figure out where AD stores its midi loops on disk, and to import them into Rosegarden by regular midi file import. It would be interesting if one could make a plugin which a festige-runable executable program available as a plugin. It would proba...

I did some googling and found a program called mididing (http://das.nasophon.de/mididings/) which does filtering of midi streams. Below is a mididings script to removes the "all notes off" signals from my midi stream so that the sustain pedal now works correctly in Qtractor and linuxsample...

Thank you for your reply which was correct. I'm using a 22 year old Roland RD300s keyboard that indeed sends an "all notes off" message when all notes have been released. Pianoteq has a midi message screen so I can monitor the midi stream from my keyboard. I used VMPK (virtual keyboard) si...

I am puzzled by the behavior of using the sustain pedal with linuxsampler which does not work as I expect. I have run linuxsampler with both Jsampler and Qsampler using the SFZ format SalamanderPiano as well as the giga format maestro_concert_grand_v2, and get the same behavior in all combinations. ...
