1. General Description

The QS1532 is a high quality PCM synthesizer LSI for General MIDI Sound Modules comparable

to Roland's SC-xx series.

Its playback capability is provided by an internal MIDI handler that supports the full GS spec.

Equipped with the HWASS QPCM synthesizer, the QS1532 is capable of generating up to 48

polyphonics at various sample rates, and can also apply effects.

Two kinds of special effects are supported to improve the liveness and reality of the sound,

known as Reverb and Chorus in the General MIDI specification.

The QS1532 contains a delay memory of 32k words to implement these features, along with a

32Mbit sound font for GS.

MIDI data is received from the host via MIDI_IN, and are interpreted simultaneously with MIDI

messages by the MIDI handler.

Most of control parameters can be adjusted real time during the synthesis of the musical notes

according to the GS specification.

The QS1532 is the best solution to put at the heart of your designs for digital pianos,

karaoke machines, electric keyboards, and all other sorts of digital musical instruments.
