I am thinking of buying a drum program, like EZ drummer 2, to create my own drum tracks. Can I record these drum tracks from the computer to input channels on the model 24 to record them to the sd card. Then I can record guitars, bass, vocals directly onto the model 24. I like the idea of recording on the analog recorder but a live drummer isn't always available. I'm new to computer recording, so if this is possible what do I need?
