EDIT PROGRAM /

CUTOFF FREQ Sets the initial cutoff frequency for the selected filter type.

RESONANCE This allows you to sharpen the point at the cutoff frequency thereby

emphasising the harmonics at that point in some way (the exact effect

depends on the type of filter selected). The range is 0-15.

NOTE: Because of the high amounts of gain boost that take place with resonance, high settings

of resonance can cause distortion. If you experience such distortion, either back off the

resonance parameter a bit or, alternatively, reduce the input level to the filter using the

ATTENUATION parameter described below.

In extreme cases where the above measures do not reduce distortion, one option is to re-scale

the level of the actual sample(s) down in EDIT SAMPLE / MASTER.

KEYBOARD TRACK Here you may set the keyboard to track the filter. This is so that you can

achieve an even tone across the keyboard range. +12 is the default and

this tracks the filter octave for octave - i.e. for every shift of pitch of one

octave, there is an according shift in cutoff frequency.

MOD INPUT 1/2/3 Here you may set the depth of the selected filter modulation controllers.

Different controllers may be assigned and mixed at these inputs for a

wide variety of filter sweeps and effects. These can range from subtle

timbral changes on an acoustic piano sound by routing a small amount

of velocity control. On the other hand, you could mix LFO1 (whose rate

is being controlled by, say, the modwheel) in with LFO 2 (whose depth is

being controlled by, say, the AUX ENVELOPE and whose rate is being

controlled by velocity) and also an inverted version of the AMP ENV for

outrageous synthesiser effects!

Pressing the mod input keys twice allows you to change the controller

assigned to the input.

FILT ENVELOPE Takes you to the filter’s dedicated ADSR envelope page.

FILT ENV DEPTH Sets the amount of sweep by the filter’s envelope. Note that this is a

duplication of the same parameter in the FILTER ENVELOPE page - it

is included here for convenience.

NOTE: When using the VOWELISER filter, because of the way the filter envelope controls the

filter, it is recommended that this parameter is set to +000

ATTENUATION This allows you to turn down the level of the signal going to the filters to

compensate for potential distortion when using high resonance settings.

The range is 0-30dB in 6dB steps. 0dB is the normal setting but if you

experience any distortion with higher resonance settings, try adjusting

ATTENUATION.

NOTE: The gain boost produced by the ‘+’ type filters (i.e. 2-POLE LP+, 2-POLE BP+ and 1-

POLE HP+ can be so severe that even an ATTENUATION setting of -30dB may not be enough

to reduce distortion. In this case, back off the resonance a little or try other means of level

reduction.
