13. Module reference: Envelope group
completed one or more of the stages, the envelope will jump directly to the corresponding level in the
release stage.
T
RIG INPUT
A high logic signal appearing at this yellow input will trig the envelope. The LED lights up while
the envelope is receiving a signal with a value greater than 0 units. A triggered envelope only
needs a short high logic signal to start. When the envelope has started after a Trig signal, it will proceed
to the very end of the cycle even if the Trig signal drops to zero
N/R
BUTTON
By default, when you release a key and then press is
again, the envelope will restart the attack stage at the
current release level and not from zero. This is
normally the behavior you would want in an
amplitude envelope. However, for pitch and filter
envelopes it's often more desirable if the envelope
always restarts at zero level. Click the N/R button
to force the envelope to always restart the attack
stage at zero level.
AM
INPUT
A control signal input used for controlling the overall amplitude of the envelope. If you want a
velocity sensitive envelope, patch any of the Velocity output of the Keyboard module to the AM
input of the Envelope module.
S
HAPE SCROLL BUTTON
Set the characteristics of the attack
and decay/release stage(s) of the
envelope by clicking this scroll
button. There are four alternatives:
Logarithmic Attack & Exponential
Decay/Release, Linear Attack &
Exponential Decay/Release, Exponential Attack & Decay/Release and Linear Attack & Decay/Release.
A(
)
TTACK
Sets the attack time. When the envelope receives a high logic signal at the Gate input, the output
control signal from the envelope rises up to the maximum value, 64 units. The time to get from
0 to 64 units is the attack time. If the logic Gate signal drops to zero before the envelope has
completed the attack stage, it will skip the decay and sustain stages and immediately proceed with
the release stage. The attack time is displayed in milliseconds or seconds in the corresponding display box.
Range: 0.5 ms to 45 s.
D(
)
ECAY
Sets the decay time. After the envelope has completed the attack part, it will drop down to the
sustain level with the decay time. The decay is exponential. If the sustain level is 64, the decay
stage will not be needed, there is simply nothing to decay down to. If the logic Gate signal drops
to zero before the envelope has completed the decay stage, it will immediately proceed with the
release stage. The decay time is displayed in milliseconds or seconds in the corresponding display box.
Range: 0.5 ms to 45 s.
