[ Free modulation ]
The free modulation section is at the bottom left hand corner, it the
arpeggiator
page is open click
on the
mod
button at the upper right corner of the
arpeggiator
screen to open the Free modulation section.
This section holds 2 Envelopes, 2 LFO's and a Modulation matrix with
8
slots.
The free modulation section is added to give you extra tools for addi
tional sound shaping options.
For instance, if you wish to make an FM synthesis sound you can address the Envelope to the FM amount
inside oscillators 2 and 3.
Or maybe you would like a stereo panning effect by an LFO.
Another option is to connect the
arp
eggiator
free or velocity row to other parameters inside Predator.
Envelope 1 and 2
Each envelope has its own destination. With Envelope 1 you also have the option to control the amount of
modulation either by midi or synth part.
The
destination
paramete
r is the one that will be changed over time by the Envelope. For example the pitch
of an oscillator. Listen to preset "Pred Brass" in the first bank.
An envelope is a time based modulation inside a synthesizer.
If you press a key it rises from 0% up to 100% and back down 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 amount of time it takes to reach 100%
The second part is know as the decay, this is the time it tak
es to reach the sustain (the final) level. If the level
of sustain is for instance 50, then the decay falls to 50% and stays there.
Finally when you release the key, the envelope lowers to 0%, during the period that you have set.
An extra feature inside
Predator is Fade. Fade adds a second part to the sustain, when it is positive the
sustain level rises to 100% over a set period, if it is negative then the sustain level falls to 0% over a set
period.
