To play the effects stored in memory, the effects must be loaded into the waveform sequencer. The effects can then be launched by the use of the GO bit.

The waveform sequencer queues up to eight waveform identifiers for playback. A waveform identifier is an integer value referring to the index position of a waveform in the Header Block (see Figure 7-6). Upon assertion of the GO bit, playback begins at register 0x03. When playback of that waveform ends, the waveform sequencer plays the next waveform identifier in register 0x04 if the identifier stored in register 0x04 is non-zero. Th waveform sequencer continues in this way until the sequencer reaches an identifier value of zero or until all eight identifiers are played as shown in Figure 7-9.
