I just downloaded cakewalk yesterday and tried to test out a simple drum track. I'm not using a MIDI and am instead just clicking on the drum set on the screen for the SI-Drum kit 1. I armed the track and pressed the record button but when I stop the recording nothing happens. I can see the sound levels rise when I hit a drum when recording, but cakewalk seems to refuse to acknowledge that I'm playing when it comes to actually writing notes to the track. Can anyone help?
