however, high keyboard velocities will increase the decay rate and low keyboard veloci-
ties will decrease the decay rate. Negative values have the opposite effect. The higher the
value the greater the effect of keyboard velocity on the embouchure & pitch envelope
decay rate.
Dpth To Emb
≤
0 ... 64.
This parameter determines how deeply the settings in this display page affect
embouchure. The higher the value the greater the effect.
Dpth To Ptch
≤
0 ... 64.
This parameter determines how deeply the settings in this display page affect pitch.
The higher the value the greater the effect.
Hold Time
≤
0 ... 127.
Sets the hold time of the embouchure & pitch envelope. That is, the length of time
the initial envelope level is held before the decay portion of the envelope begins (see
"Initial Lvl", below). The higher the value the longer the hold time.
63
0
Initial Lvl
Hold Time
-64
Initial Lvl
≤
-64 ... 63.
Sets the initial level of the embouchure & pitch envelope. That is, the level of the
envelope (pitch in the case of the pitch parameter) at the instant a key is played. The
higher the value the higher the initial level.
• If the "Initial Lvl" parameter is set to "0" the embouchure & pitch
envelope has no effect.
Decay Rate
≤
0 ... 127.
Sets the decay rate of the embouchure & pitch envelope. That is, the rate at which
the envelope level (pitch in the case of the pitch parameter) changes from the initial level
to "0" after the hold time has elapsed. The higher the value the faster the decay rate.
