Hello,
I use the master branch of zynthian-ui, but bugs prevent me to properly develop the engine.
Is there a stable branch of zynthian-ui that I can use to develop the engine?
Thanks
The master branch is the most stable branch. What bugs are preventing you to develop? You should open issues for those bugs and specify in a detailed way how to reproduce them.
Thanks!
OK,
I’ve created this issue : https://github.com/zynthian/zynthian-issue-tracking/issues/190 on github
Maybe jackpeak isn’t working as it should or even is not installed at all.
You can try to build it again by running from command line
/zynthian/zynthian-ui/jackpeak/build.sh
Thanks for the rely,
It actually solves the problem! Icould have my first sounds out of Sfizz on Zynthian! 
I’m know facing another issue : I can only assign one sound to the Sfizz engine. When I load a SFZ file on a second engine, both the engine play the same sound…
Is there a best practice to address this issue? I’m thinking about launching the command in background (with a & at the end of the command). Do you think of a better idea?
Thanks for your support.

Check it’s not just sending midi connections to the first instance.
HI @ll,
I made an installation recipe for sfizz. I can add the LV2-plugin inside MOD-UI but I currently have no plan how to load SFZ files…
Here is the installation script:
#!/bin/bash
cd ${ZYNTHIAN_PLUGINS_SRC_DIR}
sudo apt-get install libxcb-util0-dev libxcb-keysyms1-dev libxcb-xkb-dev libxkbcom
mon-x11-dev
git clone https://github.com/sfztools/sfizz.git sfizz.lv2
cd sfizz.lv2
mkdir build
cd build
git submodule update --init --recursive
cmake ..
make -j4
make install
mv /usr/local/lib/lv2/sfizz.lv2 ${ZYNTHIAN_PLUGINS_DIR}/lv2/
make clean
cd ${ZYNTHIAN_PLUGINS_SRC_DIR}

I try, but I have this error:
E: Unable to locate package libxkbcom
E: Unable to locate package mon-x11-dev
so I must do some upgrade…
Hard coding the Soundfont data (as a workaround) would be fine with me for a single instrument lv2 using one of the massive piano samples. (as a poor man’s Pianoteq)
You can find some .sf2 pianos diluted down to <100Mb as well as recorded samples here.
A 25.4Mb (uncompressed) SalamanderC5-Lite, Grand Piano SoundFont derived from a 1.12GB original, reduced to 7 velocity layers, with looping. not totally public domain.
Another test case: the 57Mb OggVorbis compressed SFZ version of SalamanderGrandPianoV2 (may require desktop decompress on the fly power, uses 641 .ogg files) HERE
2 other SFZ scheme examples can be found HERE.
“Sfizz is the recommended SFZ synthesizer for FreePats’ sound banks.”
I have only tested these using the Sforzando, which I consider just a reference standard player. (I just noticed that velocity is mapped over the length of their virtual keyboard keys) It’s using their Aria (SFZ) Player engine which cam be used as a plug-in (Audio Unit, VST, RTAS) (might only be distributed in sound bundles)
An aside: schristiancollins.com says:
For desktop Linux users, I recommend using Plogue sforzando through Wine. Sforzando’s SFZ 2.0 implementation is just miles ahead of anything that runs natively on Linux at this point in time (3/5/2016). Both Linux projects I am aware of (LinuxSampler and calfbox) are currently lacking support for many features. (He called Fluidsynth the best SF2 player)
Ok, thanks for testing. I already had both packages installed on my Zynthian. Here is the script with a fix for those problems (I hope):
#!/bin/bash
cd ${ZYNTHIAN_PLUGINS_SRC_DIR}
sudo apt-get install libxcb-util0-dev libxcb-keysyms1-dev libxcb-xkb-dev libxkbcommon-x11-dev libxkbcommon-x11-dev libxkbcommon0
git clone https://github.com/sfztools/sfizz.git sfizz.lv2
cd sfizz.lv2
mkdir build
cd build
git submodule update --init --recursive
cmake ..
make -j4
make install
mv /usr/local/lib/lv2/sfizz.lv2 ${ZYNTHIAN_PLUGINS_DIR}/lv2/
make clean
cd ${ZYNTHIAN_PLUGINS_SRC_DIR}

Wow, ran your recipe, searched for new presets… and BINGO. now I need to start playing with Polyphone and start building soundfonts that will work with a breath controller! Awesome!
Oops… it was there only for a minute or two. It must have crashed. I’ll check later. Is anyone running Sfizz on the Test Branch?
I rebooted and sfizz is working. Is the default voice a tenor sax ? I have sfizz on channel 8 and a LinuxSample tenor sax loaded on channel 1. and WOW… I changed it to Tuba and Wow. At the present state use Linux Sample on channel one to load the soundfont ?
I just installed sfizz on my zynthian and it works like a charm. I had to install “zenity” for getting the LV2 GUI running:
apt-get -y install zenity
After that, the LV2-GUI works too, but i can’t open any of the dialogs: load file, etc.
Could anybody confirm this problem? Solutions?
Regards,
How are you installing sfizz?
I am updating to the sfizz development branch and observed these errors:

I don’t know if they have an impact but worth mentioning.
Hi @zynthianers!
Good news!! I’ve an initial implementation for the sfizz engine that should replace linuxsampler one.
You simply point your zynthian-ui & zynthian-sys repos to “sfizz” branch and update 
Enjoy!!

A Specs. survey
Being interested in CC Modulation capabilities, I found:
The SFZ standards have no tidy central Modulator input list, got from text searches:

Text colors are just a formatting artifact.
(Haven’t looked into the 44 ccX codes)
Sfizz currently has implemented a total of 496 Opcodes, for 4 different standards:
SFZ v1 96% (182)
SFZ v2 75% (157)
Cakewalk 20% (53)
ARIA 57% (82)
sfizz defines 1 unique Opcode: label_keyN
Apparently 26 ccN codes for SFZ v1, and 30 ccN codes for SFZ v2
There are quite a few SFZ Opcodes slated for removal from the standards (marked pink), including I believe.
SFZ v1: 95 (of 194 total)
SFZ v2: 105 (of 205 total):
??? Could you elaborate a little bit? 
oh, easy 
the engine is loaded, the channel is selected.
this is followed by loading the sfz instrument… and nothing loads except the name.
