Linux Sampler on a RPI4B?

Wed Jul 15, 2020 4:23 am

Has anyone managed to get Linux Sampler up and running on RPI4B with RPIoS?

Several packages from the LinuxSampler project are available in apt (qsampler amongst others) but the core backend component of the system linuxsampler is not available. I have not been able to compile the linuxsampler-2.1.1.tar.bz2 source from the project's website due missing alsa davelopment header so I thought I'd check if anyone has recently pursued this.

According to the download page the software is for Linux running on x86 CPU Architecture:

The information is out there....you just have to let it in.

My other Linux machines are a ChromeBox & Intel CoreDuo Desktop

PPC is supported and I have seen old references to patches to support ARM.
qsample and gigedit both install (with apt) and run on PI4 but without the backend they are useless.

Getting ready to move my music keyboard project back on the the Pi, on the Pi 4B.
If you didn't know about the patches, here's a handy pointer.
I've built Linuxsampler for ARM and run it on Pi 2B and 3B (and built the rt-preempt kernel!) using the patches.
It's just nonsense that the patches aren't conditionals in the build.
Gad, if I can find the energy, I should submit the patched sources wrapped in conditionals.
Anyway, I can tell you from previous experience that Linuxsampler works great on Pi4B. On an overclocked 8GB version?
Well, at that point, it's going to be just plain amazing.
I don't remember the status of Pianoteq for Pi, but I think you could run the Ivy Audio Piano AKA Piano In 162 on a 4B with decently fast storage.
Personally, I love the Skerrat London Piano for character and stereo imaging.

Thanks for the details, I have managed to compile linuxsampler and qsampler following the outline in the readme file and am pleased to report it seems to be running however I have only tried some sf2 files and one sfz file.
You may be interested in trying one or two of the sf2 files from:
