SNC88040
24-Channel MIDI/Speech Controller
5.7. Sampling Rate Counters
Each voice channel of 24 is equipped with an independent sampling rate counter to
allow individual sample rate play back per channel. Channel sample rate play back
can be dynamically set from 4KHz to 64KHz. Each sampling rate counter is updated
on a period of 0.125uS. This architecture yields a high-quality music/voice synthesis
that sounds very close to its original source when played through the same amplifier
and speaker circuitry.
5.8. Auto Repetition
Each voice channel of 24 is equipped with a hardware auto repeat function. Auto
repeat functions are normally used to implement sustain in instrument synthesis but
can even be used to repeat any voice data of arbitrary length.
5.9. Voice Synthesizer
The Major function of Voice Synthesizer is to fetch Wave data from ROM and
synthesize into voice. Each voice channel of 24 is equipped with an individual volume
setting.
5.10. Music Synthesizer
The SNC88040 has a separate built in hardware music synthesizer for playing MIDI or
melody sequences. Compatible with the MIDI stream format, sequencer note
resolution is 480 ticks per quarter-note (tpqn) with tempo range settings from 16-400
beats per minute (BPM).
