I am using Studio One 3 with a Blackstar ID Core 10 guitar amp. I want to record my guitar through the amp and the guitar DAW Blackstar Insider.
But whenever I choose the amp as input Audio option and click record, I get a high pitched noise every 5-6 seconds. When I unclick the record button it disappears. So the noise only appears when I want to record, whether it is audio mono or stereo.
I have tried different USB ports and cables, as suggested by Blackstar support. I use MacBook Pro El Capitan.
