The FILTER Section
CUT-OFF
= Lowpass filter cut off point.
Q
= Emphasis = Resonance
ENVELOPE
adds the envelope modulation amount to the cut off frequency.
NOTE
adds a voltage according to the note number send to the MIDI input. The full
counter clockwise position means no key tracking; Fully clockwise gives 200 % tracking.
That is, playing an octave above the previous note will raise the cut-off frequency by 2
octaves.
VELOCITY
opens the filter according the velocity of played notes. The more you turn
this knob clockwise, the greater effect velocity has on the cut-off (until the filter is fully
open anyway). Thus, playing with full force will raise the cut-off and make the sound
brighter. Playing softly will only alter the sound by a small amount (almost in-audible).
This can be very expressive.
The Filter may be modulated by the LFO (refe
r to “LFO” in "
The Digital Section
")
The Filter and Amplifier Envelope Sections
The MonoWave(X) has two analogue ADSR-style envelope generators. They are
optimised for short but very precisely controlled timescales.
ATTACK
time can be adjusted between 6mS and 820mS,
DECAY
time can be adjusted between 16mS and 6000mS,
RELEASE
time can be adjusted between 16mS and 6000mS.
Note: There is a special hold mode
Let the
ATTACK
phase finish
Set
DECAY
below
2
.
Turn
SUSTAIN
above
9
And
RELEASE
above
2
.
All these conditions must be met at the same time.
The last note played will ring endlessly. If you experience a hanging note, check if you
have set the ADSR to `hold mode
’ by accident.
The
Amplifier Envelope
has an additional
VELOCITY
control that allows you to change
the level of velocity modulation - useful for dynamic control.
If set to zero (full counter clockwise), velocity will have no effect on loudness. At maximum
(fully clockwise) the velocity value will have maximum velocity effect. That is, near to no
volume at all if played very softly and maximum volume if played real hard. The maximum
volume you may gain will always be the same. This way you don't overdrive or destroy
your audio equipment.
