Sustain Knob; Release Knob; Amplifier; Lfo - Behringer Pro-1 Operation Manual

AP099 Revision 1.01 CM100B

Sustain Knob

Varies level from zero to maximum. Remember, this is a level control, not a time control.
(SUSTAIN time is the period between the end of the DECAY and when the key is released.)
If SUSTAIN is set at maximum then the DECAY knob setting is irrelevant.

Release Knob

Varies time for envelope to decrease from sustain level to zero, from 2 milliseconds to more
than 6 seconds. If the key is released before either the ATTACK or DECAY periods have
elapsed, this knob controls the time taken for the output to drop to zero from its level when
the key was released.
If the ATTACK and DECAY periods have elapsed and SUSTAIN is set to 0, the RELEASE knob
setting is irrelevant.
Amplifier
The ATTACK, DECAY, SUSTAIN, and RELEASE knobs in this module shape the envelope
applied to the final
VCA in the same
manner as the
corresponding
controls in the FILTER
module.
Unless the SUSTAIN
knob is somewhat
advanced, nothing
will be heard after
the ATTACK and
DECAY periods have elapsed.

LFO

Frequency Knob

Varies LFO range from approximately .1 to
30 Hz.

Wave Shape Switches

Function identically to OSC B, although there
is no pulse width control for the pulse wave,
it is simply a 50% square wave..

Modulation

A synthesiser's expressiveness stands on its modulation facilities. The Pro-One has three
modulation sources which are fully mixable and routable over simultaneous WHEEL-
controlled or DIRECT paths to five destinations in the voice itself. This is where the 'magic'
happens.
