Signal flow The picture below shows the basic signal flow in Monotone: Monotone signal flowchart. • The “heart” of Monotone is the Oscillator section, which generates the basic audio signal. There are two oscillators in Monotone, that can produce a number of traditional “analog” waveforms - plus a Noise generator, which produces white noise. The two oscillators can be detuned, to create a fatter sound. Oscillator 2 can also frequency modulate Oscillator 1, for metallic/bell type sounds. • The signal from the Oscillator section is routed to the Filter. The Filter in Monotone is a classic 24 dB/octave lowpass ladder filter, with overdrive control. • The signal from the Filter is routed to the Amplifier. The Amplifier is controlled by a standard ADSR (Attack-Decay-Sustain-Release) envelope. • The signal from the Amplifier is then routed to the Chorus module. This module generates a chorus effects, to make the sound fat and wide. • The signal from the Chorus is then routed to the Delay module. Here you can add audio delay effects. • The remaining section in Monotone (Envelopes and LFO) can be used for modulating some Oscillator and Filter parameters.
