Some of us are still using 32-Bit systems, so could you please add AppImage for 32-Bit systems. I dont even dare to ask for .deb package (sources are available, but I hate installing many of dev files and then still sth is missing anyhow).
Just got an old Yamaha MU50 from a friend and this software is as far as I can see the only working way to configure this device from Linux. I even got it compiled and working on a Raspberry Pi. Full screen support that can be enabled via the menu would be a great feature for cases like this where you do not want to waste precious screen estate on the small touchscreen with window decorations.
