General Description
The HT3494 is a CMOS VLSI designed for mu-
sical instruments, especially 49-key multi-func-
tion instruments. The HT3494 is built-in with a
controller and an ETS (Electrical Tone Synthe-
sizer).
The HT3494 provides built-in melodies,
rhythms, timbers and percussion/voice outputs.
Tempo adjustable
Memory function with 26 notes recordable
Auto-bass-chord function
Transpose function
5-chord effect
Vibrato function
Sustain effect
Fill-in effect
Chord with single or multi-keys pressed
Chord with a key synchronously pressed
2 seven-segment LEDs to display operation
status
Indicator for chord operation
40 DIP enclosed
The status of operating system is displayed
through 2 seven-segment LEDs.
The HT3494 also provides an auto-bass-chord
function, memory function as well as program-
mable rhythm in addition to basic playing func-
tions.
