Pre-Filter Distortion

It is possible to overdrive the oscillator sound ahead of going into the Filter. This can be done

in a smooth way or in an edgy way. For the edgy setting, the following applies:

• Overdrive of the filter starts at about -3dB with a sinus waveform using only 1

oscillator

• Overdrive of the filter starts at -9dB with a sinus waveform using 2 oscillators

• Overdrive of the filter starts at -12dB with a sinus waveform using 3 oscillators

So be careful with the volume of the oscillators if you are in edgy filter overdrive mode. The

smooth overdrive is more "subtle" and less aggressive than the edgy setting. Also distortion in

smooth setting starts only if you open up the drive amount. Try it out yourself and open the

resonance (Q) to hear the difference in sound with both distortion modes.

Cutoff Frequency Modulation

Envelope

Adds a positive or negative Cutoff frequency Envelope amount. The 'Envelope' is part of the

Filter section itself. Keep in mind that if you use negative modulation, the effect of the

envelope is reversed.

Velocity

Adds a positive or negative Cutoff frequency modulation by the amount of velocity used. If

Predator-RE is in arpeggiator mode (Play mode) the arpeggiator velocity settings are active.

Keytrack

Adds a positive or negative Cutoff frequency modulation by the keyboard note position. With

positive amount, the Cutoff frequency goes up the higher you play the keyboard With negative

amount, the Cutoff frequency goes down the higher you play the keyboard.

LFO

Adds negative or positive Cutoff frequency modulation by the 'Filter LFO'.

Mod.Wheel

Adds negative or positive Cutoff frequency modulation by the 'Modulation Wheel'.

Filter Envelope

The Filter Envelope is assigned to the main filter Cutoff Frequency of Predator-RE and the

amount is controlled by the Env amount in the Filter section. An envelope is a time-based

modulation section in a synthesizer. If you press a key it moves from 0% up to 100% and

back to 0% when you release the key.

Between this you can adjust the time how it does do this. The first part is known as the attack,

this is the time it takes to reach 100% The second part is known as the decay, this is the time

it takes to reach the sustain (the final) level. If this level of sustain is for instance 50, the decay

goes down to 50% and stays there. Finally when you release the key, the envelope goes to

0%, during the period that you just set.

An extra feature of the Predator-RE envelopes is Fade. Fade adds a second part to the

sustain level, when it is positive, the sustain level goes up to 100% over a set period, if it is

negative then the sustain level goes down to 0% over a set period. This is a handy feature if

you want the Cutoff frequency of the filter to rise whilst holding the keys. Listen to patch

"Syntho Brass" in the first folder.
