ML2860 DATA SHEET
16-Tone, 32-Poly Hi-Grade PCM Sound Generator LSI Version 1.0.1, Revised on Wednesday, February 20, 2002
GENERAL DESCRIPTION
ML2860 is a PCM-based hi-grade sound generator LSI, develped specifically for music ringers as used in cellular/PHS phones. With an on-chip high-quality General MIDI sound set, ML2860 is capable of playing 16 tones and 32 polyphonies simultaneously. Using the on-chip three FIFOs which store musical score data, MIDI message and ADPCM audio data, a fantastic music ringer subsystem can readily be built around this chip.
APPLICATION EXAMPLES
Mobile phone, PHS, Fax, PDA (Note ) Please appreciate that ML2860 is not offered for musical instrument and toy applications, such as keyboards.

FREQUENTLY ASKED QUESTIONS
Q1. What kind of musical score formats does the ML2860 support? A1. ML2860 can play Standard MIDI files under given conditions and the Oki original musical score format directly. If Standard MIDI file format 1/0 or Karaoke function need to be supported, Oki provides sample software based on NDA for this purpose. Q2. What is the condition for playing Standard MIDI file directly? A2. (1) Play format 0 only, do not play format 1. (2) Eliminate text and MIDI events not supported by the ML2860. Q3. Which MIDI events does the ML2860 support? A3. Note On/Off / Program change / Pitch bend / Channel pressure Control change [Modulation / Volume / Pan / Expression / Sustain / Reset all controller / All note off] RPN [Pitch bend sensitivity / Fine tuning / Coarse tuning] Q4. Does the ML2860 support synchronization of LED with ADPCM playback ? A4. Yes. LED and ADPCM functions are included in the musical score and are assigned as percussion to MIDI channel 10. It is necessary to build a software routine for this synchronization.
