ATTACK time: This parameter determines the time
required for the voltage to reach its maximum from
the moment a key is played.
ENV-1 Attack Time

ENV2 ATT
ENV-2 Attack Time

ENV 1 DECY
DECAY time: This determines the time required for
the voltage to drop from the maximum to the sustain
(when key is held down) level.
ENV-1 Decay Time
92
ENV2 DECY
ENV-2 Decay Time
83
ENV1 SUS
SUSTAIN level: This sets the sustain (when key is
held down) level to which the voltage falls at the end
of the Decay time. Therefore, at its maximum setting,
the Decay time control has no effect.
ENV-1 Sustain Level
93
ENV2 SUS
ENV-2 Sustain Level
84
ENV1 REL
RELEASE time: This sets the time required for the
voltage to reach zero from the moment a key is
released.

OFF
This changes the time required for an ENV curve to
complete its curve (= ENV time). In the OFF position,
all pitches (notes) have the same ENV time. As the
value is increased, higher keys have a shorter ENV
time.

PROCEDURE
1. Press the TONE Edit Button. The Display responds with:
2. Using the relevant Ten Keys, assign the number of the parameter you wish to edit.
As shown on the right, press the keys in the correct order, then press the ENTER
key.
3. Press a key on the keyboard. When you hear the sound, change the value to suit.
4. To continue to edit other parameters, repeat steps 2 – 4.
The α Dial also can be used to call a parameter. Press the TONE, then the PARAM button - then rotate the α Dial.
The parameter shown in the Display will change sequentially. When the parameter you require is shown, press the
VALUE edit button then edit the value with the α Dial.
When you have finished editing the Tone, press the TONE button. The TONE button indicator will go out and the
Display will then return to its normal indication except that the Tone Number now flashes to show that the Tone has
been edited - but not yet written into memory. If you call another Patch Memory at this stage, the edited Tone will
be erased. To keep your edit, execute the WRITE procedure.
