4.1

Host-controlled MP3 + High Quality Wavetable Player

Figure 4-1.

Host-controlled MP3 + High Quality Wavetable Player

• Concurrent MP3 + wavetable

• Legendary Dream

® high quality wavetable sound

• Typical polyphony:

– 56 voices with effects (reverb, chorus, etc.) @48 kHz sampling rate

– MP3 decode + 32 voices with effects @48 kHz sampling rate

• External wavetable ROM/Flash choice from 4 Mbits to 128 Mbits

• Choice of host communication interfaces

– 8-bit parallel

– Asynchronous serial (MIDI)

– Synchronous serial (SPI)

• Built-in Standard Midi file player (SMF) dramatically reduces host load
