Mode, an envelope will restart after the beat time selected from the Repeat chooser. In Beat
Mode, the repeat time is de ned in fractions of song time, but notes are not quantized.
If you play a note a bit out of sync, it will repeat perfectly but stay out of sync. In Sync
Mode however, the rst repetition is quantized to the nearest 16th note and, as a result, all
following repetitions are synced to the song tempo. Note that Sync Mode only works if the
song is playing, and otherwise it will behave like Beat Mode.
Note:
To avoid the audible clicks caused by restarting from its
initial level
, a looped envelope
will restart from its
actual level
and move with the set attack rate to peak level.
There is also a mode called Trigger that is ideal for working with percussive sounds. In this
mode, note off is ignored. This means that the length of time a key is held has no effect on
the length of the sound.
The rates of all the envelopes in Operator can be scaled in unison by the Time control in
the global section of the shell. Note that beat-time values in Beat and Sync Modes are not
in uenced by the global Time parameter. Envelope rates can be further modi ed by note
pitch, as dictated by the Time<Key parameter in the global section's display. The rate of an
individual envelope can also be modi ed by velocity using the Time<Vel parameter. These
modulations in conjunction with the loop feature can be used to create very, very complex
things...
The pitch envelope can be turned on or off for each individual oscillator and for the LFO
using the Destination A-D and LFO buttons in its display. The intensity of this envelope's
modulation of these targets can be adjusted by the Dest. A slider and the envelope can be
turned off altogether via the switch in the pitch section of the shell.
Like the LFO, the pitch envelope can modulate an additional parameter as chosen by the
Dest. B chooser. The intensity of this modulation is determined by the Amt. B slider and
the main Pitch Env value.
The pitch and lter envelopes each have an additional parameter called
End
, which deter-
mines the level the envelope will move to after the key is released. The rate of this envelope
segment is determined by the release time.
Tip:
If the pitch envelope is only applied to the LFO and is looping, it can serve as another
LFO, modulating the rate of the rst. And, since the envelope of the LFO itself can loop, it
can serve as a third LFO modulating the intensity of the rst!
