Hello Kalle,
Thanks for the info. :) As i said i'm new at Cakewalk.
Let me explain detailed:
I tried open a blank project and record my guitar over blank project.
There's no other channel expect my guitar. I added Audio to channel section. Connect my guitar at the guitar input at U-24. Disable hardware monitoring with turning knob. And i just pressed the input echo button. But there's no sound. I can see sound input is working because input lights flashing.
If i add another audio to play over with it. There's still no sound. All sound is suddenly cutted out when i click input echo, or record icon. :(
I'll upload a video about problem today. I wish it's a small problem.
