Yamaha DX27 EN - Manual (Page 40)

The data range is from 0 to 3. At 0 RATE SCALING is OFF, and at 3 the greatest,
variation in envelope length is produced.
KEYBOARD RATE SCALING
R S
These values are added
to AR, DIR, D2R ac-
cording to the Rate
Scaling setting. Only 1/2
of these values are ad-
ded to RR.
22: LEVEL SCALING
This parameter produces a gradual decrease in note output level towards the right
(high) end of the keyboard. Many acoustic instruments exhibit a gradual decrease
in level toward the higher notes, and this function can be used to create a natural
overall keyboard response for any particular voice.
The data range is from 0 to 99. At 0, no level scaling is applied. At 99, the deepest
keyboard level scaling effect is produced, and the highest note on the keyboard
may be almost inaudible. Set this parameter for the most natural overall balance
for the particular voice.
23: TRANSPOSE
This function permits transposing the pitch of the entire DX27 keyboard up or down
two octaves in semitone steps.
The data range is from C1 to C5 (C3 is middle C, C2 is one octave lower than
middle C, C4 is one octave higher than middle C, etc.). Immediately after this
function is called, the desired new key can be selected simply by pressing any note
on the keyboard between C1 and C5 (within a plus or minus two-octave range
of middle C). The keyboard’s C3 key then assumes the pitch of the key played,
and all other keys are adjusted automatically. Pressing any key higher than C5
on the keyboard results in a transposition to C5. This method of data entry can
only be used once, immediately after the TRANSPOSE function is called. Further
alterations may be made using the DATA ENTRY control or –1/+1 switches.
EG COPY
EG COPY allows you to copy ENVELOPE GENERATOR parameters (AR, D1R,
D1L, D2R, RR) and Keyboard Scaling (RATE, LEVEL) from one operator to another
operator.
While in the EDIT mode, select a Source operator via the OPERATOR SELECT button
at the far left of the DX27 panel. Next, press the EG COPY function button (this
is the same as the STORE button). The LCD will respond with “EG Copy
OP1
± OP?" You may then select a destination operator via the OPERATOR/AMS
ON-OFF buttons. While holding down the EG COPY button, select a destination.
Release, and repeat for any other operator destination you wish to copy into.
