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.
