FYI, SysEx Controls 0.2.27 is out with Korg nanoPAD2 support and several fixes and minor changes.
It’s a handy little application for Linux to configure MIDI devices. Right now, it’s mainly a replacement for Arturia’s MIDI Control Center, but it also supports a few Akai and Korg devices.
No binary builds except flatpak: https://flathub.org/en/apps/hu.irl.sysex-controls
