THE EFFECTS
THE FILTER
This effect recreates (for many dance music producers and remixers) the most essential part of a classic analogue synthesizer, the
filter, and puts it under the direct control of the tempo of the source music via the synchronised Low Frequency Oscillator (LFO).
The Filter allows you to remove or accentuate frequencies in the source signal, the [FREQUENCY] parameter controlling the
frequencies to which the changes will be applied. [RESONANCE] allows you to boost the frequencies around the current cut-off
frequency, accentuating the action of the filter, especially under the control of the LFO.
ENVELOPE MODULATION is factory set @ 75%
This is the amount of feedback present in the filter effect, which determines just how exaggerated it becomes.
FREQUENCY [ X ]
This parameter sets the basic cut-off frequency of the filter which, in [SINGLE] mode, is fixed as a LOW PASS type. (LOW, BAND &
HIGH pass filter types are used in [MULTI] mode -see VOICE SHEET for further details).
When the [X] encoder is at the home position the frequency will be at its mid point.
As the encoder is rotated anti-clockwise the frequency will decrease.
As the encoder is rotated clockwise the centre the frequency will increase.
LFO DEPTH [Y]: single mode [A] only:
In single mode[A] the LFO depth can be turned off to allow purely manual control.
This parameter sets the amount of change (depth) of the cut-off frequency as set by the FREQUENCY [X} control.
The [HIGH-MID-LOW] isolators are used to select either Low Pass, Band Pass or High Pass filter mode.
RESONANCE [ Y ]: multi-mode [B~F] only:
In multi-mode [B~F] the filter frequency i s always modulated by the LFO.
This parameter sets the boost level of the frequencies around the cut-off point as set by the [FREQUENCY] control.
When the [Y] encoder is in the centre position the resonance will be at its mid point.
As the encoder is rotated anti-clockwise the resonance level will decrease.
As the encoder is rotated clockwise the resonance level will increase until, at the edge position the resonance will reach self-
oscillation producing a new pitched element similar to acoustic feedback.
