In Sound Module mode, the front panel controls on the MC-303 are inactive. To manipulate the sounds, you will need to send continuous controller messages from your sequencer. Let's look at some specific examples of these controllers and what you can do with them. You will normally insert these messages into the event list editor on your sequencer. Please note that you will need to specify the MIDI channel for the part you are going to be editing. Also, make sure that you enter these messages in the order shown. They will not work if your MC-303 receives them in the wrong order.
