• Stereo knob and field: Determine the relative phase shift between the left and right
channels.
• A value of 0 changes the level of both channels—in phase.
• A value of 180 (out-of-phase modulation), results in a stereo tremolo effect that is
also known as auto panning. This is similar to manually turning the pan pot from side
to side.
Tip: The original Wurlitzer Piano has a mono tremolo with a fixed modulation rate
of 5.5Hz. For an authentic Wurlitzer sound, select a Stereo value of 0degrees. For
Rhodes sounds, set the Stereo value to 180degrees. The settings in between result in
spacious effects—especially when low Rate knob values are used.

Model parameters
• Voices knob and field: Set the maximum number of voices that can sound
simultaneously. Lower the value to limit polyphony. When Voices is set to 1, Vintage
Electric Piano is monophonic. The maximum value is 88, allowing for glissandi over the
entire keyboard range when the sustain pedal is depressed.
• Decay knob and field: Set the decay time of the piano sound. The lower the value, the
less the sound sustains and the higher the level of damping applied to the vibration of
the tines. When short values are set, the main tone is more pronounced and is heard for
a longer period than the transient harmonics. Sonically, the effect is reminiscent of an
electric guitar string being damped with the palm of the picking hand. Electric pianos
can be modified in a similar way. Higher values (longer settings) result in more sustain
and a less dynamic feel.
• Release knob and field: Set the amount of damping applied after the keys are released.
Extremely long settings (high Release values) let you play the piano like a vibraphone.
