Functions

calculateKSL void calculateKSL(ubyte note): Calculates KSL values
keyOff void keyOff(int sampleRate): Sets the key to off on this channel. Also calculates adaptive release rates if needed.
setEG void setEG(int sampleRate, ubyte note, float vel): Sets the Envelop generator
setFrequency void setFrequency(int slmpFreq, ubyte note, double pitchBend, double tuning): Sets the frequency of the operator Also calculates KSL levels
setShpVals void setShpVals(float vel): Recalculates shape params.

Variables

eg ADSREnvelopGenerator eg;: The envelop generator of the operator.
fbL float fbL;: Calculated feedback level containing KSL damping
feedback int feedback;: Feedback register. Either out_0[n-1] or out[n-1] multiplied by feedback amount. The amount which the oscillator will be offsetted. Negative if inverted.
input int input;: Input register. The amount which the oscillator will be offsetted.
outL float outL;: Calculated output level containing KSL damping
output int output;: Output register. Not affected by either level or EG Might be used for ring modulation.
output_0 int output_0;: Output affected by EEG and level. Either used for audible output, or to modulate other operators
pos uint pos;: The current position of the oscillator, including fractions.
preset Preset.Op preset;: Local copy of operator preset data.
shpA0 float shpA0;: Live calculated out of shpA
shpR0 float shpR0;: Live calculated out of shpR
step uint step;: The amount the oscillator must be stepped forward each cycle, including fractions.
