Section 8 — Understanding Programs TS-10 Musician’s Manual
26
You are now free to create a new custom pitch-table in your current program.
Now that you understand the relationship between the source key, playback pitch, and fine
tuning in a custom pitch-table, let’s start over. This time we’ll work with an ancient tuning
system, called Pythagorean. Then, we’ll work with the TS-10 built-in pitch-table calculator, and
two new procedures: Extrapolation and Interpolation.
Creating and Extrapolating a Custom Pitch-Table
The EXTRAPOLATE command takes the pitch-table relationships from within a key range and
duplicates those relationships outside that range.
If you have a custom pitch-table from the previous exercise, remove as shown above.

Press Select Voice to return to the Select Voice page.
Press either of the soft buttons beneath EDIT PITCH-TABLE. This takes us to the Pitch-Table
Editor page.
The display shows the source key and playback pitch as described earlier.
To set up one octave of a Pythagorean scale, change the source keys, playback pitches, and cents,
one note at a time, from C4 to C5 — to the following values:
Source Key Playback Pitch Cents
C4 C4 00
C4+ C4+ 17
D4 D4 04
D4+ D4+ 01
E4 E4 08
F4 E4 98
F4+ F4+ 12
G4 G4 02
G4+ G4+ 14
A4 A4 06
A4+ A4 98
B4 B4 10
C5 C5 00
You can manually edit your custom pitch-table across the remaining octaves of the keyboard. Or
you can use the Calculator in the TS-10 to do this for you.
Press the soft button above *CALCULATOR*. The display reads something like this:
