Intelligent Acoustic Control (Iac); Grand Expression Modeling - Yamaha P-145 Owner's Manual

Intelligent Acoustic Control (IAC)

With this function, the sound quality of this instrument is automatically adjusted
and controlled according to the overall volume. Even when the volume is low,
this lets you hear both low sounds and high sounds clearly.
To turn on/off IAC:
While holding down [DEMO/SONG] and [PIANO/VOICE] simultaneously,
press the C#2 key to turn the function on or the C2 key to turn the function off.
To adjust IAC Depth:
While holding down [DEMO/SONG] and [PIANO/VOICE] simultaneously,
press the D2 key to decrease the value, or the E2 key to increase.
The higher the value, the more clearly that low and high sounds are heard at
lower volume levels.

Grand Expression Modeling

When a piano Voice (page 18) is selected, you can add Grand Expression
Modeling effects, which simulate the physical sound transitions of an actual
piano. When this feature is set to "Dynamic," you can control extremely subtle
nuances in the performance and sound by changing your playing strength or
touch. When set to "Static," the nuances are generally fixed. For details on Grand
Expression Modeling, see page 30.
While holding down [PIANO/VOICE], press the A#3 key to turn the function
on or the A3 key to turn the function off.
