Looper module with optional amplitude and frequency modulation.

Sliders under the graph:
-AM Range: Amplitude of the amplitude modulation LFO (low frequency oscillator).
-AM Speed: Frequency of the amplitude modulation LFO.
-FM Range: Amplitude of the frequency modulation LFO.
-FM Speed: Frequency of the frequency modulation LFO.
-Loop Range: Range in the soundfile to loop.
-Dry/Wet: Mix between the original signal and the processed signal.

Dropdown menus and toggles:
-AM LFO Type: Waveform of the amplitude modulation wave (saw up, saw down, square, triangle, pulse, bipolar pulse, sample and hold or modulated sine).
-AM On/Off: To enable or disable the amplitude modulation.
-FM LFO Type: Waveform of the amplitude modulation wave (saw up, saw down, square, triangle, pulse, bipolar pulse, sample and hold or modulated sine).
-FM On/Off: To enable or disable the frequency modulation.
-# of Polyphony: Number of voices played simultaneously (polyphony); only available at initialization time.
-Polyphony Spread: Pitch variation between polyphony voices (chorus); only available at initialization time.

Graph only parameters:
-Overall Amplitude: The amplitude curve applied on the total duration of the performance.
