Pitch Eg Button (#13) - Yamaha DX7 II FD Reference Manual

Pitch EG Button
(#13)
Many musical sounds vary in pitch as well as in volume or timbre during the course of a
note. The DX7 II includes a separate envelope generator that is applied to pitch, in
addition to the individual operator level EGs. As with each operator's EG, the pitch EGis
specified by four rates and four levels. These parameters are explained in detail below.
The following diagram illustrates the output of the pitch EG.

The pitch EG affects only those operators set to the ratio oscillator mode described
with the Oscillator button (#8) above.
The Pitch EG button (#13} provides access to the following pitch envelope parameters in
a single LCD display.
Ll-L4 The level parameters of the pitch EG are very similar to their counterparts in the operator
EGs. The main difference lies in the fact that the pitch EG levels refer to pitch rather than
output level. A pitch level of 50 represents the standard pitch of the instrument
0 Lowest pitch level.
50
Standard pitch level.
9 9 Highest pitch level.
The difference in pitch between level values of 0 and 99 is determined by the range (Rng)
parameter, which is described below.
Rl-R4 The pitch EG rates are identical in function to the rates found in the operator EGs.
0 Slowest rate (longest time) from one pitch level to the next.
99 Fastest rate (shortest time) from one pitch level to the next.
