Yamaha GranTouch User Manual

Pitch

Initially the GranTouch is tuned to the standard Concert Pitch (A=440 hertz). You can, how-
ever, adjust the pitch to suit your particular application. Different pitches are sometimes 
used in vocal music and orchestral performances. The pitch can be adjusted in one hertz 
steps from 438 to 445 hertz (one hertz is about four cents). 

You’ll need a small, flat-blade screwdriver to adjust the PITCH switch, which is located on 
the right side of the Control Box, as shown below.

As well as being able to tune the GranTouch in one hertz steps with the PITCH switch, you 
can also fine tune it using the keyboard. The GranTouch can be tuned up or down 50 cents, 
in 1.2 cent steps (100 cents equals one semitone). This allows you to achieve a perfect tuning 
match between the GranTouch and another instrument, a vocalist, or a slightly off-speed 
cassette player. 

To finely tune up the GranTouch, hold down the A and B keys at the far left of the keyboard 
and press any one of the keys from middle C to B. It doesn’t matter which key you press, 
just so long as it’s in the middle C to B range, which is shown highlighted in the illustration 
below. The pitch is raised 1.2 cents for each key press.

Note:   The PITCH switch setting is remembered when the GranTouch is powered down.

Note:   Fine tuning settings are not remembered when the GranTouch is powered down.
