Synth Engine

A typical Synthesizer section is made of controls named ADSR

(Attack, Decay, Sustain, Release) and they are normally dupli-

cated for the FILTER and the AMPLITUDE controlled sections.

The simplied parameters available on the NC2x are a sub-set

of these controls, selected from the ones more eective in

the instrument’s SYNTH engine sound generation.

The ATTACK Slider controls the time that the FILTER needs to

reach the desired CUTOFF starting frequency.

The DECAY Slider controls the time that the FILTER needs to

reach the nal CUTOFF frequency, when the keys are kept pla-

yed.

NOTE: as a simplied setting, the DECAY also eects the SU-

STAIN Level (a parameter not listed within the nine Sliders) and

a long DECAY time will also simulate the nal Cuto Frequency

almost identical to the starting frequency: the sound will not

change after the ATTACK, while keeping the note played, or it

will change very slowly.

The RELEASE Slider controls the time needed by the FILTER to

reach the nal Cuto when the Keys are released.

The LFO Rate and Speed allow to control the related parame-

ters of the LFO that is internally assigned to the CUTOFF Fre-

quency; as an example, setting the values in a certain way, whi-

le the Resonance is set to mid-hi levels, could create SOUDS

with a kind of looping WOW eect.

NOTE: this LFO’s destination is the FILTER, while the Modula-

tion (Vibrato etc) is controlled either by the STICK 2 and the

AFTERTOUCH, allowing to select all possible combinations of

all settings.

PLEASE NOTE:

Both Cuto and Resonance parameters are enabled to control any other Sound of the instrument

(not only Synth Sounds) making possible to edit the starting sound, as an example make a Strings

sound mellower or an Electric Piano sound emphasized at the Cuto Frequency with the addition

or a certain level of Resonance. As mentioned before, with some setting of the Cuto + Resonance

you might have to re-balance the part Volume, to avoid clippings of unwanted side-eects, unless

you want to reach a certain sound that could also include some clipping as a desired eect.

PLEASE NOTE:

If set at values too close to the maximum, the Resonance

could create a signal level gain and consequent distortion

possible problems of the overall sound; with hi levels of Reso-

nance, the part Volume (Upper or Lower) should be reduced

proportionally, to avoid clippings or unwanted side-eects.
