When you play the Sub Phatty, your keyboard technique determines how the envelope generators
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:
Use this knob to specify 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’s
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
ATTACK
knob specifies the
time it takes the control level to ascend to its maximum value.
FILTER DECAY:
Use this knob to specify 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:
Use this knob to specify 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’s
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.
