FILTER/ENVELOPES
FILTER
These settings determine the brightness and thickness of the sound. Here you can also specify the time- varying
change (filter envelope) for the filter and the time-varying change (amp envelope) for the volume. The filter is a
24dB/ octave ladder design and again has a very similar layout when compared to a classic analog mono synth
filter section, though there are some additional controls like a contour inverting switch, restart on note press and
an option to trigger the amp with a gate or the LFO. The envelopes are really snappy and just like on the classic
analog synths, you get an ADS envelope with switches to enable release control with the decay knob.
CUTOFF
Adjusts the filter cutoff frequency. Clockwise lowers the frequency down to nominal, and counter clockwise
opens the filter completely.
EMPHASIS
Boosts the region near the filter cutoff frequency. Higher values produce greater boost, creating a
distinctively “synthesizer-like” character. This is essentially the resonance function found on most filters, where
the moving edge of the cutoff frequency is exaggerated as EMPHASIS is increased until self oscillation is
accomplished.
KEY TRACK [1/3] [2/3]
Specify how the filter cutoff frequency changes in response to the pitch that is played on the keyboard.
[1/3]:The filter cutoff frequency changes by 1/3 of the pitch change.
[2/3]:The filter cutoff frequency changes by 2/3 of the pitch change.
If both switches are on, the filter cutoff frequency changes by the same amount as the change in keyboard pitch.
CONTOUR
Adjusts the depth of change produced by the specified envelope settings. This is an effect similar to adding
a gate pulse to the filter, and the CONTOUR attenuator controls the amount that the filter envelope will impact the
frequency of the filter.
Experiment:A great way to understand this knob is to set the filter frequency nearly to off, and play a series of
notes, or a sequence. Now rotate the CONTOUR knob clockwise slowly, and listen to the introduction of the
envelope and understand how an envelope effects filter frequency.
MTRIG
If this is on, the filter envelope restarts each time you press a key. That means that if you switch MTRIG on
then with each key played, the filter envelope will re trigger. With the MTRIG switched off, the filter envelope will
not be re triggered, but the envelope shape will be completed before the next key will trigger it again from the
beginning.
