As you play the Subsequent 25 keyboard, technique determines how the Envelope Generators (EG)

respond, which impacts your musical expression and articulation. If you release the key before the

Envelope reaches either its maximum or Sustain Level, the Release Stage immediately takes effect.

When you play staccato (very short notes), the Envelope may never reach its Decay Stage, depending

on its Attack setting. Playing legato—holding down each key for the note’s full duration without lifting

your ﬁngers between notes—prevents the Envelope from retriggering its Attack Stage on subsequent

notes. In that case, the Envelope maintains its Sustain Level until you trigger the Release Stage by

lifting your ﬁnger.

ENVELOPE CONTROLS

FILTER ATTACK: This knob speciﬁes the time it takes the Filter frequency to ascend from the CUTOFF

knob’s manual setting to its maximum level, which is determined by the Filter EG AMOUNT setting. Its

value ranges from 1 millisecond to 10 seconds.

When you use the Filter Envelope to modulate pitch or wave amount, the AT TACK knob speciﬁes the

time it takes the control level to ascend to its maximum value.

FILTER DECAY: This knob speciﬁes the time it takes the Filter frequency to descend from its maximum

level to its Sustain Level. Its value ranges from 1 millisecond to 10 seconds.

When you use the Filter Envelope to modulate pitch or wave amount, the DECAY knob speciﬁes the

time it takes the control level to descend from its maximum value to its Sustain Level.

FILTER SUSTAIN: Rotating this knob will set the Filter Cutoff frequency once the Decay Stage is

complete. The Sustain stage is held until the Envelope receives a Note Off command or the Gate

ends. Its value ranges from zero to 100 percent, calibrated 1 to 10. Note that the Filter EG AMOUNT

determines the depth of its effect.

When you use the Filter Envelope to modulate pitch or wave amount, the SUSTAIN knob speciﬁes the

control value that is held once the Decay Stage is complete.

FILTER RELEASE: This knob speciﬁes the time it takes the Filter Cutoff to descend from its Sustain

value to the CUTOFF knob’s manual setting. Its value ranges from 1 millisecond to 10 seconds.

When you use the Filter Envelope to modulate pitch or wave amount, the RELEASE knob speciﬁes the

time it takes the control level to descend from the Sustain value to zero.
