• Manufacturer Part Number: msm9810b
• Description: 8-channel Mixing Oki Adpcm Type Voice Synthesis Lsi
• Manufacturer: Oki Semiconductor

Mixing Function
It is possible to mix eight channels at a time. Moreover, the LSI is capable of starting or stopping voices of each
channel separately.
• Note on waveform clamping during mixing
(Note)
Continuous Playback Function
The continuous playback function is used to continuously play back the next phrase after playing back a phrase.
The next phrase to be played can be previously selected while a phrase is being played back.
See “Continuous Playback Flowchart” for details.
The continuous playback function is also available in the case of the phase control table.
(Note)
OKI Semiconductor
Increasing the number of channels to be mixed may cause clamping.
To prevent clamping, reduce the volumes of all channels using the OPT command.
Mixing using a different sampling frequency cannot be done.
The following changes of voice synthesis algorithms are not permitted for continuous playback function.
These changes may generate noises.
• ADPCM → ADPCM2
• ADPCM2 → ADPCM
