Description
Velo

only
None / Full Envelope response to velocity
Delay MOD only
0-18
seconds
Controls the onset of the MOD envelope.
Attack All
2 ms - 18
sec
The time the voltage takes to reach maximum
Decay All
2 ms - 18
sec
The time the voltage takes to reach the Sustain level from
maximum
Sustain All Zero / Max
Voltage target for the Decay stage. If set to maximum the Decay
setting has no effect.
Release All
2 ms - 18
sec
The time the voltage takes to return to zero after the key is
released.
4.8.1. Envelope curves
Hold [Settings] and move an Attack/Decay slider to access the curves for that envelope.
Attack has its own curve setting, and the Decay/Release stages share another curve. Several
preset options are available. For a list of the presets, see the Settings chapter [p.81].
4.8.2. VCF/VCA velocity modes
Velocity can modulate the envelope times. For example, strings can have a slow attack with
low velocities and a fast attack with high velocities. Hold [Settings] and move the Velo slider
for VCF Env or VCA Env to access that envelope's velocity modes. A descriptive list of the
settings is in the Settings chapter [p.81].
4.8.3. Envelope loop modes
Each envelope can play once, loop two or three times, or loop indefinitely. To access the loop
modes:
• VCF/VCA envelopes: hold [Settings] and move the Velo slider.
• MOD envelope: hold [Settings] and move the Delay slider.
A list of the settings is in the Settings chapter [p.81].
4.9. Stereo spread
There are two settings for Stereo spread, which are accessed by holding [Settings] and
turning the Stereo knob:
• Voice pan: Each voice has a given position in the stereo field
• Voice + Filter pan: The "Voice pan" effect described above takes place when the
Series/Para control is set to Series. At the other extreme, Parallel mode pans the
Ladder filter to the left and the Steiner to the right.
Since the Series/Para parameter is continuous, intermediate settings and crossfades of
those two settings are possible.
