Creating a Patch
Stretch Tune Depth
This setting allows you to apply “stretched tuning” to the
patch. (Stretched tuning is a system by which acoustic pianos
are normally tuned, causing the lower range to be lower and
the higher range to be higher than the mathematical tuning
ratios would otherwise dictate.) With a setting of “OFF,” the
patch’s tuning will be equal temperament. A setting of “3”
will produce the greatest difference in the pitch of the low
and high ranges.
Value:
OFF, 1–3
The diagram shows the pitch change relative to equal
temperament that will occur in the low and high ranges. This
setting will have a subtle effect on the way in which chords
resonate.

Analog Feel (Analog Feel Depth)
Specifies the depth of 1/f modulation that is to be applied to
the patch. (1/f modulation is a pleasant and naturally-
occurring ratio of modulation that occurs in a babbling brook
or rustling wind.)
By adding this “1/f modulation,” you can simulate the natural
instability characteristic of an analog synthesizer.
Value:
0–127
Cutoff Offset
Cutoff Frequency Offset alters the cutoff frequency of the
overall patch, while preserving the relative differences
between the cutoff frequency values set for each tone in the
Cutoff Frequency parameters (p. 110).
Range:
-63– +63
This value is added to the cutoff frequency value of a
tone, so if the cutoff frequency value of any tone is
already set to “127” (maximum), positive “+” settings
here will not produce any change.
Resonance Offset
Resonance Offset alters the resonance of the overall patch,
while preserving the relative differences between the
resonance values set for each tone in the Resonance
parameter (p. 110).
Range:
-63– +63
*
Resonance:
emphasizes the overtones in the region of the
cutoff frequency, adding character to the sound.
This value is added to the resonance value of a tone, so
if the resonance value of any tone is already set to “127”
(maximum), positive “+” settings here will not produce
any change.
Attack Time Offset
Attack Time Offset alters the attack time of the overall patch,
while preserving the relative differences between the attack
time values set for each tone in the A-Env Time 1 parameters
(p. 115), F-Env Time 1 parameters (p. 112).
Range:
-63– +63
*
Attack Time:
The time it takes for a sound to reach maximum
volume after the key is pressed and sound begun.
This value is added to the attack time value of a tone, so
if the attack time value of any tone is already set to “127”
(maximum), positive “+” settings here will not produce
any change.
