General Description  
The HT3421A is a 41-key musical instrument  
LSI implemented in the CMOS technology. The  
chip provides 8 rhythms, 8 timbres, 4 pulsatile  
sounds, 12 demo songs, and a 62-note memory  
storage function. The 12 × 7 matrix control keys  
of the HT3421A control both basic keys and
