If you are using the original DX7, or any other for that matter, you can
fake keyboard splits with scaling by creating multiple 2 operator sounds
within an algorithm and using the scaling to have one sound at the low end,
one at the mid, and one up high. Or, using algorithms 1 through 4, you could
have two three operator sounds that cross fade across the keyboard. It's a
cool effect mixing pad/strings with bass/vibe sounds.
Hope the helps a little more

I believe that "keyboard level scaling" raises or lowers the amplitude
(loudness if you are working with a carrier) of an operator depending on
what part of the keyboard a note is played on. You have linear
(straight) and exponential (curved) scaling, positive and negative (raise
or lower amplitude). You set a center key, (C4 or whatever key you want)
then you can specify how an operator gains or loses amplitude when a note
is played above or below that point. The diagram illustrates this.
Hope this helps.
