The Envelopes (ENVS) Section/Menu
The Envelopes section allows the Amplitude, Modulation and A/D (Attack/Decay) Envelopes to be adjusted.
The Amplitude Envelope is the level of the signal from the Oscillators section over time. The Modulation
Envelope can be used to control three other area of the synth: Oscillator pitch, Oscillator pulse width and
Filter frequency – each with individual settings in the respective sections or menus. The A/D Envelope can
be used to modulate Oscillator 3 and control the FM amount. The options for AMP and MOD envelopes are
as follows:
Attack – sets the amount of time taken for the envelope to reach maximum level
Decay – sets the amount of time taken for the envelope to fall to the sustain level after maximum level
has been reached
Sustain – sets the level when a note is held down after the decay period
Release – sets the amount of time taken for the level to decrease when a note is released
The three buttons can be used to set the Trigger of each envelope. This sets whether or not an envelope is
triggered with every key press, and is only applicable when the Oscillator section is in Monophonic Mode (see
the Oscillators section for details). For example, you may want the AMP envelope to only be triggered on the
first note of a legato phrase (so the phrase gets progressively quieter) but the MOD envelope to be triggered
on ever
y key pr
ess; in this case, the AMP ENV TRIG should be set to SGL (Single) and the MOD ENV TRIG to
MLT (Multi). Press each button to alternate between these states.
The r
emaining Envelope controls are adjusted in the Envelopes Menu, accessed by pressing the
Menus/Audio button (so that the lower LED lights) followed by the button above ‘env’. Once in the Envelopes
Menu, use the page up/down buttons next to the LCD screen to cycle through the following pages, using
the data encoder to change the settings for each page:
ENV Amp Velocity – sets the amount that velocity effects the volume of the sound. Setting a negative value
has the opposite effect (decreasing when pressed harder)
