Hi, I am impressed, but.. I run Ubuntu 21.04 LTS .. up to date. and an AMD 64-bit processor on an ASRock ATX (about 2012 vintage). 1). Please allow the file browse and select function go to my External USB 1TB HDD. It does not see it. Perhaps because it uses a Windows formatting, not Unix, for portability between systems. 2). I picked up, with fre:ac immediately after downloading and installing the snap, a folder of .wav files, pre-copied from my Columbia label CD. Everything went swimmingly.......
