Info

The main page of the Tool contains a few global settings, as well as buttons to display pages for designing specific kinds of tunings. Tonic Key Number and Tonic Frequency specify a MIDI key number and the corresponding frequency in hertz. These two parameters are used to specify a “fixed point” between all of the tunings; no matter which tuning is selected, the specified key number will always play at the specified frequency. The default value specifies middle C and its frequency in the conventional equal tempered tuning system. In the middle of this page, you can specify the kind of sound to be used for auditioning the scale. Use the radio buttons to choose between a 21 harmonic sawtooth oscillator, a sine wave oscillator, or a sample. Click the Choose… button to choose the sample to be used from a file dialog. The Volume fader (active at all times through MIDI continuous controller 7) controls the volume of the sound being played. The five buttons provide access to the five different ways to design tunings in this Tool: ♦ Ratio Scale is used to design 12-note octave scales by specifying the ratio of each scale degree to the tonic. ♦ Cents Scale is used to design 12-note octave scales by specifying the number of cents difference between each scale degree and the tonic. ♦ Equal Tempered is used to design equal tempered scales with an arbitrary number of scale degrees per octave. ♦ Two Interval is used to design scales with an arbitrary number of scale degrees per octave, where the scale is made up by raising an interval to successively larger powers. Also called a y x scale. ♦ From Text File is used to design completely arbitrary scales. 452
Clicking on Ratio Scale brings up this page. Across the top are twelve fields for the numerator and twelve fields for the denominator of the twelve ratios that define the scale. The buttons at the lower left are used to preset the ratios to three different example ratio scales. ‡ To change a value, click the mouse in the field, and type in the new value. To cause the tuning to be updated with the new value, either press Enter, press Tab to go to the next field, or click in a different field. The central view is common to all of the tuning pages in this Tool. It describes an octave starting on the tonic key number specified on the main page. It lists the MIDI key number, the absolute frequency of that key number in this scale, the ratio of the scale degree to the tonic, and the cents difference in pitch between the tonic and the scale degree. The buttons at the lower right are also common to all of the tuning pages in this Tool: ♦ Create Example opens an untitled Sound file window containing an example using the current tuning and currently selected instrument. ♦ Load allows you to select a text file containing a tuning that you had saved earlier. The information in the file is then used to set the parameters in the current tuning method. The Tool either uses the information in the file directly (if the current tuning method is the same as the one used when saving the file), or it comes up with a set of parameters for this tuning method that approximates the tuning in the text file. ♦ Save saves the parameters for the current tuning into a text file. Even though the Tool shows only one octave of the scale, the text file contains a listing of the frequencies in hertz of the 128 MIDI key numbers. You may find it useful to open this file with a text editor to view or edit that information. ♦ Back takes you back to the main tuning page. ‡ Thanks to Brian Belet of the San Jose State University for providing the ratios of the “BB Sharp Chromatic (5-limit) Just Scale” used for the Just scale example. 453
