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.
