Polyphonic Sound Generator ICs
| ML2871/72/73/74/63/65 – Pin Compatible Family of Polyphonic Sound Generators |
The new pin and software compatible family of highly sophisticated MIDI sound generators are based on a PCM wavetable primarily designed for mobile phones and PDAs, although not exclusively. They also replay ADPCM/ PCM
speech and sound data. Based on a general
MIDI sound set, plus traditional Chinese
|
(except ML2872/65) and BRICs (ML2874 only)
instruments, the family can cover playback of
16 to 64 polyphonic tones and 8 additional
sound effect (ADPCM/PCM) channels.
