Tuning Map
Program Tuning Maps are primarily used to emulate stretched tuning techniques, which
are commonly used for acoustic pianos and other acoustic keyboard instruments. Stretched
tunings generally tune notes in the lowest octave increasingly flat, and notes in the highest
octave increasingly sharp. For solo piano performances, stretched tunings can make the
overtones and harmonics of notes in these lowest and highest octaves sound more in tune
with notes in the middle octaves.
Three stretched tuning maps are included, Railsback (a common stretched tuning), Grand
Eight Ft (based on a grand piano), and Tines EPiano (based on a common electric piano
service manual).
When layering piano with other instruments using equal temperament (non-stretched)
tunings, using an equal temperament piano tuning may be preferable so that notes in the
lowest and highest octaves sound more in tune with other instruments which use equal
temperament tuning. In this case, set the Tuning Map to 0 None to use equal temperament
tuning.
Monophonic
When the Monophonic parameter is set to "Off", the current edited program is
polyphonic—it can play multiple notes at a time.
When the Monophonic parameter is set to "On", the program will play only one note at
a time, and the Legato parameter and the four Portamento parameters will appear on the
Program Common page. The Monophonic, Legato and Portamento parameters are not
available for KB3 programs.
Legato
When the Monophonic parameter is set to "On", the Legato parameter appears. The Legato
parameter is useful for emulating legato techniques of various acoustic instruments. When
the Legato parameter is set to "On", a played note will trigger a new amplitude envelope only
if no other notes in the program are being held. Notes played while other notes are being
held will use the previously triggered amplitude envelope of the first note that was played.
Portamento
When the Monophonic parameter is set to "On", the Portamento parameter appears.
When the Portamento parameter is set to "On", notes played in a monophonic Program can
glide from the pitch of the previously played note to the pitch of the currently played note.
Portamento is often used in synthesizer lead sounds, or to mimic acoustic instruments like
violin and bass, where a pitch glide is achieved by sliding a finger along a vibrating string.
