Thanks Jack,
Audio interface and cakewalk is in ASIO mode. Minus one track is dragged to the cakewalk as TRACK 1 and my vocal is on Track 2.
What i am trying to achieve is to record my vocal (only) in track 2 while is playing track 1 (minus one). Only track2 (vocal) is press red button ready to record. When listening on track 2 should be only vocal, but you can hear them combine#???
It does work if i do record an instrument first in track 1 and vocal after that.?
