DCAs
Each oscillator is followed by a DCA, which can modulate the level of the wave either statically (you set a particular
volume level) or dynamically (the level changes over time in a specific way).
Having four DCAs allows for, among other effects, cross-fades between the four oscillators. Example: One DCA could
fade out a flute sound while the other DCA fades in a synth waveform to create a synth flute sound.
The "Amp Env" is a DCA that follows the filter. The ampenv generally sets the overall dynamics.
Pan
This sets the panning modulation of an oscillator pair and sends it to die audio outputs.
Filters
This is a 2 or 4 pole "analog-sounding" filter with resonance. There is one filter for each oscillator pair. This can be:
0-2pole Loiv Pass Passes the frequencies up to the Cutoff point.
1-4pole Low Pass Passes the frequencies up to the Cutoff point with a steeper cutoff rate.
2
- Band Pass Passes only a narrow band of frequencies.
3
- High Pass Passes the frequencies above the Cutoff point.
