FM synthesizer functions
■ Voices
FM synthesizer is capable of creating countless voices theoretically.
When synthesizing voices, it is necessary to designate the number of operators to be used for the synthesis.
Increasing the number of operators allows synthesis of tones that are more intricate and closer to those
generated by natural musical instruments.
YMU759C supports synthesis of tones of two types including 2-operator voices and 4-operator voices.
Because operator's wave shape can be chosen from eight kinds, the quality of sound improves more
remarkably than the MA-1 series. (MA-1 series support 2-operator voice and have two kinds of operator wave
shape)
■ Number of voices simultaneously generated
YMU759C is equipped with 32 operators.
The number of simultaneous pronunciation changes by whether 2-operator voices are used or 4-operator
voices are used (Combining is impossible).
When 2-operator voices are used: 16 tones can be pronounced simultaneously.
(It means that the number of pronunciation channels is 16.)
When 4-operator voices are used: 8 tones can be pronounced simultaneously.
(It means that the number of pronunciation channels is 8.)
■ Voice allocation function
Voice to be used can be set for each channel to pronounce.
For example, it is possible to pronounce all channels with the same voice by setting the voice parameter for
one voice and assigning it to all channels using voice allocation function.
■ Compatible with stereophonic sound generation.
■ Volume control
Channel volume, master volume, expression, and pan pot control in individual channels
■ Sequencer is built in.
■ Can interpret SMAF (Synthetic music Mobile Application Format) directly.
■ Equipped with four systems of 96 FIFOs for sequence data.
■ Supports direct access that directly controls FM synthesizer.
■ Supports key control with half an octave higher and lower.
ADPCM reproduction function
■ Equipped with ADPCM decoder with 4 bits, 1 channel
■ Supports two kinds of sampling frequency, 4 kHz and 8 kHz.
■ Sequencer is built in.
■ Equipped with 348 byte FIFO for ADPCM data and 32 byte FIFO for sequence data
■ Supports direct access that directly controls ADPCM section.
Speaker amplifier and equalizer circuit
■ Output of speaker amplifier: 580 mW when SPVDD=3.6 V, or 400 mW when SPVDD=3.0 V
■ Balanced input speaker amplifier provides low ripple
■ Built-in equalizer circuit corrects the difference of frequency response among the speakers and forms of
bodies.
CPU Interface
■ Parallel interface of 8 bit data bus
