hi, I downloaded the free version of presonus studio one yesterday: I configured everything following the instructions but, when recording, I cannot arm the track for recording: when I click on the button (both from the mixer and from the arrange window) the light does not turn red.
my operating system is mac OS high sierra (10.13.6) on iMac (27-inch, Mid 2011), the sound card is the duet 2 and it is perfectly recognized by studio one: I don't use any antivirus; I can hear the sound of my guitar, but I can't record it: in fact the problem arose at the first attempt to record an audio track.
what can I do?
