I have not seen your XDeleteProperty error before, so I cannot help you there, but I will comment that with Fedora you can get Qsampler from the CCRMA repositories. It is version 2.2, but unfortunately has only support for GIG, and not SFZ or SF2. To get those you must compile libgig, linuxsampler, ...

Generally speaking to use linuxsampler you need to install linuxsampler, libgig, and jsampler and/or qsampler as front-ends. I do not know the specific package names in Ubuntu but it should be easy to figure out. Then run either jsampler or qsampler as a GUI front end to linuxsampler.

This is a completely naive comment, but I'm assuming the the EQ op codes get the sampler engine to provide equalization. Wouldn't it be more efficient to process your samples with whatever effects you want and just use those samples? It seems like it would save the sampling engine CPU time and hence...

You need to compile the SVN version of QSampler to get SFZ support.

You need to compile libgig and linuxsampler from SVN to get SFZ support. If you are a Linux user you might consider trying AVLinux or DreamStudio which both have the SVN version of Linuxsampler (with SF2, SFZ support) already built-in.

Both AVLinux and DreamStudio have the SVN version of Linuxsampler (with SF2, SFZ support) already built-in so either one of those is an easy way to get started with LinuxSampler. Of course, you need to know something about Jack, and Linux audio too.

You have to load an instrument in LS and create the audio and midi ports for LS to be seen by JACK. This can be done on the command line, with Jsampler-Fantasia, or Qsampler, for example. Note that you can create multiple instruments in LS, each with its own audio and midi ports.

What you are doing is correct - works for me on AVLinux. Are you using QJackCtl? If so click on the "Connections" button and make sure Rosegarden's outputs are connected to system playback. Otherwise, check that audio is not otherwise muted. In Qsampler does the green "LED" on the piano channel blin...

I have 2 suggestions: Use an audio-oriented Linux distribution like AVLinux which already comes well-configured with audio apps so you can avoid a lot of setup issues. Or just run Linuxsampler with an external program like Qsampler or Jsampler-fantasia and route the midi out of Rosegarden using, say...

I finally found out what my real problem is with sustain pedals. I have an old midi keyboard (Roland RD300s from 1989), which puts out a control 123 "All Notes Off" whenever all notes have been released. This "All Notes Off" turns of off the sustain. I have fixed by problem by running my midi stream...
