Overview of the TD-30 How the Sound Generator is Organized Overview Broadly speaking, the TD-30 consists of a controller section, sound generator section, and sequencer section. TD-30 Sound Playback Sequencer section generator Patterns section Setup TRIGGER INPUT jacks Record Perform (Trigger signals) Performance Controller section (Pads and pedals) Controller section Settings The pads and pedals on which you perform are called controllers. When a pad is struck it outputs a âtrigger signal.â That signal is input to a TRIGGER INPUT jack on the rear panel of the TD-30, and is received by the sound generator section. Sound generator section This section produces the sound. Sequencer section Expansion It receives trigger signals from the controllers, the onboard sequencer or an external MIDI device, and plays the instruments accordingly. This section can record what you play on the TD-30, and then be used to play that performance back. It can transmit MIDI messages from the MIDI OUT or USB Computer port connectors to control an external MIDI device. Appendices 15
