The VELOCITY SENSITIVE BALANCE parameter makes the digital oscillator balance
dependent on key velocity. A soft touch will yield the mix set by param 34, and a hard touch will
favor oscillator 2. The D.O. BALANCE (param. 34) will set the initial balance for a soft touch.
Parameter 35 controls how much the balance changes with velocity, with one exception. When
the value is '0' the balance between oscillators is controlled by the MODULATION WHEEL
instead. Since each oscillator can play a different wavesample, it is possible to mix between two
totally different sounds.
36/Filter Fc (00-99)
The FILTER CUTOFF FREQUENCY parameter adjusts the initial cutoff frequency of the low
pass filter, The filter is adjustable from 50 Hz (VALUE 0) TO 15KHz (VALUE 99) and features
a 24 db/octave rolloff slope. The effects of the filter envelope, and the filter keyboard tracking
are added to the level set here.
37/Filter Q (00-40)
The FILTER RESONANCE (Q) controls the amplitude of the resonant peak of the filter. It is
adjustable from no peak (VALUE 0) to just below oscillation (VALUE 40).
38/Filter Tracking (00-04)
The FILTER KEYBOARD TRACKING parameter allows the note played on the keyboard to
determine the cutoff frequency of the filter - lower notes will have a lower cutoff, higher notes a
higher cutoff. It is adjustable from no tracking (VALUE 0) to one octave in filter cutoff per
octave on keyboard (VALUE 4).
The Mirage offers you a wide range of control over the amplitude and filter envelopes of a
sound. In addition to being able to create fixed envelopes, you can use the keyboard velocity
sensitivity feature to control any or all of the parameters of an envelope. Note that many of the
envelope parameters are particularly dependent on the fixed envelope parameters.
40/Filter Attack (00-31)
The FILTER ATTACK parameter controls the rate at which the filter frequency will increase
from the initial CUTOFF FREQUENCY (param. 36) to the peak frequency. It is adjustable from
instantaneous (VALUE 0) to 30 seconds (VALUE 31). Note that the peak level has no effect on
the rate of the attack.
