Tuning With The Mt-90U - Roland MT-90U Owner's Manual

When using the remote control
1.
To use the remote control, point the remote control toward the MT-90U's sensor and
operate it within the specified operating range.
NOTE
Some notes on using the remote control
• The remote control does not function when two or more buttons are pressed at the same time.
• Even within the sensor range, the remote control may not function if something is obstructing
the sensor path, or if the remote is held at an awkward angle.
• Using the remote near other devices that use infrared rays, or using a remote other than the
one supplied with the MT-90U can cause malfunction.
• Battery life varies depending on how the remote is used. When the battery wears down, the
sensor range decreases. The battery should be replaced when this happens.
• If you are not going to use the remote control for a long period of time, take the battery out
and store it somewhere for use later.
• Shining a bright light, such as a spot light, on the remote sensor can decrease the sensor's
responsiveness.
• Use only the specified type (model no. CR2025) of lithium battery. Be sure to insert it as
directed (to ensure correct polarity).

Tuning with the MT-90U

Match the pitches of the instruments you are using to a standard pitch with the MT-90U
for a beautiful, resonant sound. Matching instruments to a standard pitch is called
"tuning."
NOTE
<fig.01-09.eps>
The operating range is about 4 meters away from and 30 degrees to the right
and left of the sensor.
What is standard pitch?
The middle A note (440Hz), also known as "concert A," is the standard tuning pitch.
You cannot use an audio file as the MT-90U's standard pitch.
