Dave Smith Instruments Sequential Prophet-6 Operation Manual page 31

High levels of resonance can sometimes cause the Prophet-6 outputs to clip
if its sound generators are also set to high output in the Mixer. Monitor your outputs
carefully to ensure optimal, clean signal levels. If you experience signal clipping, try
reducing the levels of the oscillators in the
the Amplifier Envelope, or the
filter.

the filters. Higher amounts more dramatically affect the cutoff frequency.
This control is bipolar. Positive settings produce standard behavior as
described in "Filter Envelope" on page 22. Negative settings invert the
envelope. Experiment with this control to create a variety of expressive
filtering effects.

filter, the harder you play, the more the filter will open and the brighter
the sound will be. Conversely, if the

Keyboard: off, half, full
keyboard to the filter's cutoff frequency. Selecting
that the higher the note played on the keyboard, the more the filter opens.
This is useful for adding brightness to a sound as higher notes are played,
which is typically how acoustic instruments behave. If both
are off, keyboard filter tracking is off, meaning that filter frequency is unaf-
fected by playing higher or lower notes on the keyboard.
On the Low-Pass Filter, setting
will cause the filter-generated pitch to follow the keyboard in tune (i.e. in semitones).
