FILTER ENVELOPE CONTROLS (CONTINUED)
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 0% to
100%, 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.
RELEASE
Use this knob to specify the time it takes the filter cutoff to descend from its current 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 current value to zero.
MULTI TRIG
By default, playing legato on the Sub 37 prevents envelopes from retriggering on subsequent notes;
this is called single triggering. You can change this behavior by pressing the MULTI TRIG button.
When lit, a new gate occurs each time you play a note on the keyboard, regardless of whether you’ve
released the previous key; this is called multiple triggering.
RESET
By default, with envelope reset turned off, an envelope Attack sweeps the envelope output only from its
current level to maximum. When the RESET button is lit the Attack starts from minimum regardless of
the level at the time of the key press. This effect is more prominent with longer attack and release times.
SYNC
When the SYNC button is lit the envelope will retrigger at every unit of the beat. The FILTER EG
CLOCK DIV parameter in the PRESET EDIT menu allows you to determine the clock division at which
the envelope will retrigger. (See MIDI Table on page 52 for available units of the beat.)
LOOP
Normally, an envelope occurs just once when you play a note. When LOOP is illuminated, an envelope’s
delay, attack, hold, decay, and release stages will loop continuously for as long as a note is held.
Because of this, it is possible to use the filter’s envelope generator as a multistage LFO. The shorter the
envelope times, the faster the loop will repeat.
LATCH ON
When the LATCH ON button is lit the FILTER ENVELOPE will remain at its SUSTAIN level, as if the gate was on.
FILTER ENVELOPE CONTROLS (KNOB SHIFT ON)
DE LAY
When the KNOB SHIFT button is blinking you can use the FILTER ATTACK knob (now FILTER DELAY)
to specify a timed pause before the onset of the filter envelope’s attack, effectively turning the ADSR
envelope into a DADSR envelope. To increase the time before the onset of attack, engage the KNOB
SHIFT button and turn up the filter envelope’s ATTACK knob. The envelope’s delay time ranges from a
minimum of 0 millisecond to a maximum of 10 seconds.
