This voice is called HARPSI- PIANO simply because the lower range sounds much
VOICE 5: like an acoustic piano while the upper range has a more harpsichord-like timbre.
HARPSI-PIANO ALGORITHM 1 is used with carrier OP1 and all three modulators contributing to
the total voice.

Note the rather extreme frequency ratio settings of ОР 3 and OP4. These are critical
to the voice. Try changing the frequency ratio of OP3, in particular, and see how
much it changes the timbre of the voice. By modifying the frequency ratios of OP3
and OP4 it is possible to create a broad range of interesting and very useful voices.
Also note that the heavy KEYBOARD SCALINGLEVEL is required on OP2, OP3
and OP4 to maintain the quality of the voice across the entire keyboard range. If
you reduce these level scaling values, the notes at the top of the keyboard range
will become unbearably sharp and tinny.
The TRANSPOSE parameter is set to C2—an octave lower than usual—to take
advantage of the fat, rich string effect in the lower keyboard range.
