The Piano Tuning Reference
Piano Tuning Reference
The piano tuning reference is a very convenient tool which is useful for many studio
applications. Use your mouse to click a desired note on the keyboard.
Level
Use your mouse to select an output level ranging from off to 0 dB.
Note Select
This one-octave keyboard lets you use your mouse to select the note or key to use as
a tuning reference.
Wave Select
This offers two separate waveforms that can be used as the tuning source tone. The
squiggly line icon is a sine wave with three harmonics, and the sine wave symbol is
a pure sine wave tone. It may be easier for some to tune to a pure sign wave, while
the addition of harmonics can often assist in tuning instruments such as bass or the
lower two strings of a guitar.
Semi-Tone
This offers a +/– semi-tone pitch shift to accommodate alternate instrument tunings.
Use your mouse to raise or lower the Semi-Tone control or scroll the digits in the
window.
Cents
This raises or lowers a selected semi-tone up to + or – 50 cents. The default is zero.
Combine your mouse and control key to reset to 0.
(
Note:
A cent is a unit of a pitch interval equivalent to 1/100th of the semi-tone.)
Start
Left-click to start the tuning reference, click again to stop. Right-click to play a mo-
mentary tone burst for as long as you hold down the button.
