TUNE This is a fine tune control for the pitch of the oscillator. It has approximately a +/- 1 semitone
range. When this control is in the mid-position, the oscillator should generate the correct pitch
programmed into the sequencer. Use this control to fine tune the Revolution with other equipment.
If larger changes in frequency are required, you can transpose the patterns within the sequencer.
CUTOFF The cutoff control adjusts the point at which high frequencies become reduced in the
lowpass filter. Turning this control clockwise will allow more high frequencies to pass through the
filter. When this control is turned counter-clockwise, high frequencies will be attenuated and only
lower frequencies will be heard.
RESONANCE The resonance control is used to accentuate the frequencies closest to the filter’s
cutoff frequency. Turning this control clockwise will cause the sound to become thinner with more of
a liquid quality. When this control is turned counter-clockwise, the sound will become full and no
resonance will be heard.
ENVELOPE The envelope control adjusts the amount of affect the filter’s envelope signal will have
on the filter’s cutoff frequency. As you turn this control clockwise, the envelope will sweep the cutoff
frequency over a greater range. When turned counter-clockwise, the filter’s envelope will have very
little affect on the filter’s cutoff frequency.
ENV DECAY This is the filter’s envelope decay control, which will vary the decay time for the
filter’s envelope. Turning this control clockwise will create longer envelope decay times, allowing
high frequencies to pass through the filter for a longer amount of time. Turning this control counter-
clockwise will shorten the amount of time high frequencies can pass through the filter.
Note: The total decay time for the filter’s envelope is actually the sum of the ACCent DECAY time
and the ENVelope DECAY time. As you increase the ACCent DECAY time, the filter’s ENVelope
DECAY time will also increase. The ACCent DECAY time simply sets the shortest possible
decay time for the filter’s envelope.
