Specifications
Env 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. 
Velocity: 0…127 – Amount of key velocity controlling the level of the filter 
envelope. 
Key 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 MIX 
to 127, O
SCILLATOR 2 SHAPE to Off, and OSCILLATOR 1 SHAPE to the desired 
waveshape. This is useful for bell-like FM sounds. A wide range of sounds can 
also be made using A
UDIO MOD with the oscillators routed normally through the 
filter. 
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. 
Amplifier 
VCA Level: 0…127 – Sets a base level for the VCA (Voltage Controlled 
Amplifier). This allows the VCA to be essentially bypassed for programs that 
drone. 
Note: If VCA L
EVEL is on full, Envelope Amount has no effect. For 
typical keyboard playing, VCA L
EVEL is set to zero. 
Env Amount: 0…127 – Sets the amount of VCA envelope to the VCA level. 
Velocity: 0…127 – Sets the amount of keyboard velocity controlling the level of 
the VCA envelope. 
Pan Spread: 0...127 – There is a pan circuit after the VCA that pans the audio 
in the stereo field individually per voice. With a P
AN SPREAD of zero, all eight 
voices are panned in the middle (monophonic). As you turn up P
AN SPREAD, the
