Notes:
• You cannot use tones 160–167
(drum set tones) as base tones.
• The preset tone you use as the
basis for a user tone is not changed.
• The tone locations 168–199 are not
empty (before you store user tones
there). They initially contain dupli-
cate versions of tone numbers 128–
159. The user tone you store in any
of those locations replaces the exist-
ing tone. If you delete a user tone,
the keyboard automatically restores
the initial, duplicate tone there.
The parameters you can change are di-
vided into four groups. For the details of
each parameter, see "Creating and Stor-
ing a User Tone."

Understanding 1DCO and
2DCO Tones
A Digital Controlled Oscillator (DCO)
controls the sound output of a digital sig-
nal. Some of the MD-1200's built-in
tones are simple tones (1DCO), and
some are layered tones (2DCO). When
you select a 2DCO tone as the basis for
creating a user tone, you need to
change the parameters of both tones.
When you select a layered tone,
appears on the display, indicating that
this is the first tone of a layered tone.
