Resonance: 0…127 — 

Sets the Resonance level of the filter. At high settings 

the filter will self-oscillate in 4-pole mode. If the filter does not oscillate, switch 
to 4-pole mode. 

Keyboard Amount: 0…127 — 

Sets the amount of keyboard (MIDI note) to the 

filter cutoff. A setting of 64 will step the filter one semitone for each note, 32 
would be half-semitones, and so on. 

Audio Mod:  0...127 — 

Controls the amount of audio from Oscillator 1 used to 

modulate the filter cutoff frequency. For filter-only audio, set O

SCILLATOR 

M

IX

 

to 127, O

SCILLATOR 

2

 

S

HAPE

 to Off, and O

SCILLATOR 

1

 

S

HAPE 

to the desired 

waveshape. This is useful for bell-like FM sounds. A wide range of sounds can 
also be made using A

UDIO 

M

OD

 with the oscillators routed normally through the 

filter. 

Config: 2 Pole, 4 Pole — 

Selects either 2- or 4-pole operation for the filter. 

Envelope Amount: -127…+127 — 

Sets the amount of filter envelope routed to 

the cutoff frequency. This can be positive or negative, allowing inverted 
envelope control of the filter. 

Envelope Velocity: 0…127 — 

Amount of key velocity controlling the level of 

the filter envelope. 

Delay: 0...127 — 

Sets a delay between the time the filter envelope is triggered 

and when the Attack portion actually begins.

 

Attack: 0…127 — 

Sets the Attack time of the filter ADSR envelope generator. 

Decay: 0…127 — 

Sets the Decay time. 

Sustain: 0…127 — 

Sets the Sustain level. 

Release: 0…127 — 

Sets the Release time. 

VCA Level: 0…127 — 

Sets a base level for the VCA (Voltage Controlled 

Amplifier). This allows the VCA to be essentially bypassed, which is necessary 
for Programs that drone. 

Note: If VCA L

EVEL

 is on full, Envelope Amount has no effect. You 

normally want VCA L

EVEL

 set to zero. For droning sounds, or using the 

Mopho to process external audio, you will probably turn the VCA Level 
up.
