Tone Generator block
The Tone Generator block is what actually produces sound in response to the MIDI messages generated by playing the
keyboard, using the controllers, and the playback of the sequencer (Song/Pattern/Arpeggio).
Internal AWM2 Tone Generator and optional Plug-in boards
The tone generator block in this synthesizer consists of the built-in AWM2 sound source and optional Plug-in Board(s).
● AWM2 (Advanced Wave Memory 2)
AWM2 (Advanced Wave Memory 2) is a synthesis system based on sampled waves (sound material), and is used in many
Yamaha synthesizers. For extra realism, each AWM2 Voice uses multiple samples of a real instrument’s waveform. Furthermore,
a wide variety of parameters — envelope generator, filter, modulation, and others — can be applied.
You can also create your own waves (Samples) via microphone or from external audio equipment by using the Sampling
function. These are then stored in internal memory (DRAM) and can be used just like the preset waves.
● Plug-in Board
For details on using the optional Plug-in Boards for even more sounds, see page 74.
AMPFILTERPITCHOSC
Outputs the wave that
makes up the sound.
