SYNTHESIS STRUCTURE
The MOODULATOR is small in size, but it´s not as simple as it seems.
That's why we're going to take a look at it´s synthesis structure.
Let´s begin with the audio chain.
There are various sound sources which goes to the mixer, 2 Oscillators (also called VCOs), each of these
have their own SubOscillators, which generate a Square wave one octave below the main oscillator and
respond to pitch modulation in the same way to the main oscillator.
So if you apply vibrato to VCO1 that will also be applied to the SubOscillator 1.
There´s another mixer input, but this time you have to choose between White Noise, Pink Noise or Ring Modulator.
A last input is for external audio input at the back of the panel, and it doesn't have a volume knob.
All these signals are sent to the filter. The filter sculpt the sound and then it´s sent to the VCA for amplitude
shaping. The result of all that goes to the Audio Out and Headphones outs.
Modulation sources are three Envelope Generators, an LFOs, external MIDI and External analogue CV signals.
Filter Env modulates the filter (VCF) cutoff, the Amp Env controls the VCA, and the Mod Env is used to modulate
various parameters. LFO can control both oscillator's pitch, oscillator 1 PW and filter´s cutoff frequency.
The real fun begins with the Modulation Control section. This feature allows you to modulate various sources
in very interesting and creative ways.
