There was something that was on my (private) TODO list for quite some time now : being able to record music, mix and output a single song from multiple recorded tracks. For that you need a Digital Audio Workstation DAW.
I have several instruments at home (electric guitars, bass, digital piano and also drums) but due to lack of (free) time I never investigated the DAW part on Linux and especially CentOS. So having some "offline" days during the holidays helped me investigating that and also being able to setup a small DAW on a recycled machine. Let's consider the hardware and software parts.
I personally still own a Line6 TonePort UX2 interface which is now more than 10 years old, and that I used in the past on a iMac. The iMac still runs, but exclusively with CentOS 7 those days, and the TonePort was just collecting dust. When I tried to plug it , it wasn't really detected, but just mainly because of the kernel config, so I asked (gently) Toracat to enable the required kernel module in the centos-plus kernel and with the centos-plus kernel, the toneport ux2 is seen as an external sound card. Good :
