2)I d like also that samplerbox respond on only one midi channel, is it possible too?

Hi Benwa,
1) No, basic samplerbox does not (yet..) support this, so you have to program that yourself: react on continuous controller 7 ("note" of mesaagetype 11) in midi callback routine.
2) Similar, program limiting the channels listened to in the beginning of the same routine.
Several forum topics on both already, just have a peek to het you going. You can also check my fork at http://homspace.xs4all.nl/homspace/samplerbox for an example on how to achieve both.
Happy hacking :-)

Hi Benwa,
Here is an example on how to modify the samplerbox program (fade out length for this example). To do this, I connected the Pi to my TV via HDMI. :

Hi Petar,
No documentation on this as far as I know...
The statement is in /root/samplerBox/samplerbox.py.
When you connect you are already in /root, so it is one directory down: cd SamplerBox
Edit the script (for instance with nano as this is more friendly than vi): nano samplerbox.py
In nano, the find instruction is ^W (control-W), saving is with ^O (control-O).
Just change the 30000 to 500 and save.
Mind that you will have to do a real poweroff or reboot later (just unplugging the power might corrupt your filesystem).
But for now you can test with:
systemctl stop samplerbox
./samplerbox.sh
This will start the script in your terminal.
If you made an error, it will show up there.
Stopping the script is with ^C (control-C)
It also speeds up the process of adapting the value, should 50 milliseconds not work out right.
When all is fine, you can either reboot or issue: systemctl start samplerbox
Hope this helps (and that I didn't make any typos - this without having acces to the pi now.)

commandline is all you have (plus texteditor nano).
Reboot is reboot, power off is poweroff.
Seems obvious but I know it isn't in Linux world :-)
However if you're that unfamiliar to Linux, make sure you have the SD image backed up in case things get out of hand.
