I have one more thing to try,
I opened the sfz in Polyphony and exported it as sfz.
The sfz file changed somewhat and all the samples are now in one folder.
I will upload that one this evening.
Now that I’ve exported it to sfz (5gb) from polyphony it works but it just sounds like shit.
The samples in the computers sound fine.
I am putting this mission on hold for now, before I loose my mind.
Haha.

I got mine unzipped. I’m going to try it with linuxsampler on my laptop first. I just have to finish rebuilding linuxsampler. Good lord non-FOSS-compatable licences are annoying.
Dammit. Works fine on my laptop, No errors at all 
Have you uploaded it to your zynthian?
Yes, and the unsurprising result is…

It immediately runs out of memory and oom-killer run in and blats it. I only have the 1GiB pi4. It’s possible it might run in a 4GiB one as on my laptop it only took up about 3GiB ram. Otherwise it’s a bust. Pianoteq is probably the better bet if you want a Steinway B.
Ok. That explains.
Well we can comfort us in knowing that the Salamander is awesome.
Thanks for the help.

I have a problem with Salamander in that the dynamics change inappropriately between keys, particularly noticeable on higher keys. Playing a simple scale from C7 down to C6 I get notes being played louder and softer as I go. Also the step between samples is very noticeable. I am yet to find a free samples piano that doesn’t do this. I am amazed at Pianoteq and can’t wait until we have a platform that supports it without any xruns. I hope Santa brings me a RPi4 that does this - my RPi3 suffers the occasional xrun which is no good for me.

I don’t like Salamander because it’s just not a very bright piano. I really like Keppy’s Steinway D but it caused an uncomfortable number of xruns on the pi3 and still occasionally xruns on the pi4. Also linuxsampler doesn’t like the apostrophe character in the preset name.
Linuxsampler build script include some modifications to the default building options. This changes were made by @Schpion, a historic zynthianer and creator of this jewel:
He made greatly contribute to Linuxsampler engine and “tuned” the build script:
#Configure with optimizations from Schpion
./configure --enable-max-voices=21 --enable-max-streams=64 --enable-stream-min-refill=4096 --enable-refill-streams=2 --enable-stream-max-refill=131072 --enable-stream-size=262144 --disable-asm --enable-subfragment-size=64 --enable-eg-min-release-time=0.001 --enable-eg-bottom=0.0025 --enable-max-pitch=2 --enable-preload-samples=65536
As you can see, he touched a lot of optimization parameters related with the way LinuxSampler manage sample cache, sample reading, etc.
We should try the standard building options and compare.
LinuxSampler documentation may give some guidance about all this parameters …
Regards,
@Humi, @Baggypants, i just made some changes to the LinuxSampler build script:
- upgrade versions to the last
- comment @Schpion optimizations
You can easily rebuild LinuxSampler in your zynthian:
update_zynthian.sh
$ZYNTHIAN_SYS_DIR/scripts/recipes/install_linuxsampler_stable.sh
Regards!

After the update I am getting xruns with salamander.
And did you get to work the 5G soundfont?
If not, i would restore the @Schpion optimizations …
Yes and no
The flac soundfont played but sounded horrible. There was something very wrong.
I’m happy to reverse the update and get Salamander to work.
How do I do it?
Probably the flac one was causing a mad flurry of xruns to make it sound horrible.
Probably
Simply repeat the steps you already did:
update_zynthian.sh
$ZYNTHIAN_SYS_DIR/scripts/recipes/install_linuxsampler_stable.sh

Update again. Current code is working OK, so it should work:
update_zynthian.sh
If it doesn’t work, send the logs:
systemctl stop zynthian
zynthian.sh
