Qsismixer is a frontend gui to control the mixer for Focusrite's
Scarlett 6i6 USB sound card on Linux.  The card has a powerful
hardware mixer. I find this program easier to use than alsamixer on
the terminal or generic mixer GUI's.  Now including static
configurations: qsismix can save and load arbitrary configurations
from the command line

TODO:
an options menu would be cool
write code to dynamically generate the visual forms


PLEASE NOTE: Different versions of ALSA use different identifying
control numbers internally to refer to the 6i6's controls. These
control codes are compiled into Qsismixer at build time. Therefore,
you must build Qsismixer against the ALSA headers for the same version
as the ALSA libraries that are installed on your system. Eg, if you
built Qsismixer against ALSA < 1.1.2, and then update your system to
ALSA >= 1.1.2, you will have to rebuild Qsismixer against the new ALSA
library in order for the program to fñunction properly. Very similar
errors happen with ALSA updates 1.1.5 and 1.1.7.

Error messages related to this include:
looking for string 'Scarlett 6i6 USB-Sync'', got string 'Internal Validity'
looking for string 'Scarlett 6i6 USB-Sync'', got string 'Master Playback Volume'

Updated on 1/19/18 to correct for bug introduced by new alsa version
1.1.5:
"looking for string 'Scarlett 6i6 USB-Sync'', got string 'Scarlett 6i6
USB-Sync Clock Source'"

When your distro updates to alsa 1.1.5, you will likely get this error
and will have to recompile with the update in order to use the
program.

Updated on 4/3/18 to correct for bug introduced by a new system
update:
"looking for string 'Scarlett 6i6 USB-Sync'', got string 'S/PDIF
Validity'.

If you get this error, try adding the following definition to line 12
in include/mixsisctrl.h so it reads:
#define NEW_ALSA_CTRL_SCHEME

If you can't get the program to work with your system configuration,
simply file a bug report and I will look into it.

Updated on 11/9/19 due to ALSA update 1.1.7 breaking qsismixer again.
