Tuning the RD-170 This function allows you to change the RD-170's standard pitch so that it matches the pitch of other instruments (or a CD player, tape recorder, etc.) you are accompanying. The RD-170 is a digital instrument, which means that it never goes out of tune and that changing its tuning is a matter of pressing a few buttons rather than tuning a whole bunch of strings. (1) Press IsystemI (lights), followed by 0. (2) (3) RRSbEr fcunE Press and hold Q] to find out what the function is called ("M. Tune"). Use Idec/noI/ITnc/yesI to select a different frequency for the A4 (and hence the entire instrument). The setting range is 415.3~466.2Hz. The normal tuning of electronic musical instruments is 440Hz. Note that the first digit ("4") is omitted, so that “440Hz" is actually displayed as "HO.u". Similarly, the frequency “415.3" will be displayed as "15.3", etc. Note: This setting can be saved (see p. 32). Press IexitI to leave the System mode. Using other tunings The RD-170 allows you to play classical music, such as baroque, with the tuning actually used in that period. Most music today is composed and played based on the assumption that Equal Temperament (the most common tuning method) will be used. However, various other tunings were in existence during the age of classical music. By playing a piece using such an “old" tuning, you should be able to hear the natural sonorities of the chords and appreciate the piece in the way it was originally intended. (1) Press IsystemI (lights), followed by 00. out r DC ScRLE tunm9. Press and hold 00 to display the abbreviated function name. (2) Use iDEC/NOl/ffN c/yesI to select the desired scale. Certain scales also require that you set the root note of the key you wish to play in. See below for details. E^u (Equal): This tuning divides the octave equally into 12 intervals. Pyb (Pythagorean): This method of tuning was invented in ancient Greece. It resolves the ambiguity of the fourths and fifths. Though thirds are somewhat imperfect, melodies sound clearer. 20 RD-T70 System parameters (3) HR J (Just major): A tuning which resolved the ambiguity of fifths and thirds. Quite beautiful sonorities are produced with chords, but the scale is unbalanced, so it is not well-suited for melodies. Pun (Just minor): This is a Just scale for playing pieces in minor keys. Drib (Mean Tone): A temperament that adds some compromises to Just temperament and facilitates transposition. UEr (Werckmeister): A combination of the Mean Tone and Pythagorean temperaments, this tuning allows for playing in any key. Hir (Kirnberger): As a result of improvements made to the Mean Tone and Just temperaments, it is relatively tolerant towards transposition and can be used to play in all keys. Skip to step (5) below if you do not need to set the root note. •Specifying the root note When you play using a tuning other than Equal Temperament, you need to specify the root/ fundamental ("C" for major and "A” for minor) according to the key of the song to be played. Press IsystemI (lights), followed by 00. roob nobE Press and hold (H to display the abbreviated function name. (4) Use Idec/noI/Iinc/yesI to select the desired root note (C~B). Note: This setting can be saved (see p. 32). (5) Press IexitI to leave the System mode. Stretch Tuning "Stretch Tuning" is a tuning method specific to pianos. The pitch of a piano is generally tuned lower in the bass and higher in the treble compared with equal temperament. This is done because low notes, when tuned right, sound a little sharp, while treble notes sound flat. By changing the tuning curve, the chords will sound subtly different. Bass register A4 Treble register (1) Press IsystemI (lights), followed by 0. (2) (3) SbrEbch bumn9 Press and hold (4] to display the abbreviated function name. Use IdEc/noI/1INC7YE51 to select On or OFF. OFF refers to the standard tuning curve, which is suitable for playing in Layer mode or with other instruments. On refers to the tuning curve that stretches the bass and treble. This is suitable for piano solos. Note: This setting can be saved (see p. 32). Press IexitI to leave the System mode. Note: Stretch Tuning only applies to "Piano" Tones. Pedal detection You can connect either a footswitch (DP-2, etc.) or an expression pedal (EV-7, etc.) to the RD-170's SOFT/EXPR. socket and specify its function for the Upper and Lower parts separately (see p. 22). The RD-170 is smart enough to recognize whether you are using a footswitch or an expression pedal. (You cannot use both simultaneously, so don't try to solder the cable wires together or using a multiinput connection...
