I would like to change the tuning type on a Yamaha CP5. I could not find anything relevant in the manual, surprisingly, since cheaper models (like P-140) routinely have this setting. There is a thread indicating it was possible (Non-equal temperament on high-end Yamaha digital pianos? at pianoworld.com) but no relevant reference is given. There is just 13 option pages, one of them is Master Tune (440Hz), but I did not see anything related to tuning. Could someone confirm CP-5 does/does not make this possible?


All the manuals and documentation for the Yamaha CP5 can be found at this link:


The answer to your question is on page 27 of the English-language Reference Manual at the above link -- it is not found in the Owners Manual, which is a separate document.

The Reference Manual says:

Page 3: On-screen name (and full name) TuningNo. (Micro-Tuning Number)

This parameter is used to select a musical tuning system. In total, your CP5 or CP50 can replicate seven tuning systems. While the Equal Temperament tuning system has now become standard for pianos, a wide number of other systems were developed over the years before it was adopted, and these systems invariably paved the way for the birth of new musical styles. By selecting a different tuning system, you can play tunes from the corre- sponding styles of music and enjoy their unique nuances.

Setting values:

00 Equal Temp (Equal Temperament) The range of pitches in each octave is divided equally into twelve parts, with each half-step evenly spaced in pitch. Today, this is by far the most popular tuning system for pianos.

01 PureMaj (Pure Major)

02 PureMin (Pure Minor) These two tuning systems preserve the pure mathematical intervals of each scale, especially for triad chords (root, third, fifth). These characteristics are best heard in vocal harmonies — such as choirs and a cappella singing.

03 Pythag (Pythagorean) This scale was devised by the famous Greek philosopher, Pythagoras, and is created from a series of perfect fifths, which are collapsed into a single octave. The thirds in this tuning are not so smooth, but the fourths and fifths are beautiful and suitable for certain leads.

04 MeanTn (Mean Tone) This scale was created as an improvement on the Pythagorean scale by making the major third interval sound smoother. It was especially popular from the latter part of the 16th century to the end of the 18th century, with Handel being one of its most notable users.

05 Werckmeist (Werckmeister) 06 Kirnberger The Werckmeister and Kirnberger scales improve the mean-tone and Pythagorean scales by combining them in different ways. Both are uniquely characterized by the way in which modulation can change the nuances of individual songs. Often applied during the time of Bach and Beethoven, they are used today to reproduce the music of that era on harpsichords.

Page 3 On-screen name (and full name) TunRoot (Micro Tuning Root)

This parameter is used to select the root note for the part’s tuning system. No setting is required in the case of certain tuning systems. Setting values: C to B

  • Thanks. I looked into all setting and didn't have the idea it was per-track setting. – eudoxos Jul 26 '15 at 16:18
