Struct Vco 

pub struct Vco { /* private fields */ }

Voltage-Controlled Oscillator (VCO)

A multi-waveform oscillator with V/Oct pitch input, FM, pulse width control, and hard sync. Outputs sine, triangle, saw, and square waveforms.

The saw and square outputs are bandlimited with PolyBLEP and the triangle with PolyBLAMP to suppress aliasing; the sine is inherently bandlimited.

FM inputs

• Port 1 fm (exponential): a raw ±5V CvBipolar signal is treated as ±5 octaves (freq = base * 2^fm), i.e. full-scale ±5V spans ×32 / ÷32. Attenuate it for musical depths.
• Port 4 fm_lin (linear, through-zero): adds to the frequency directly, scaled so ±5V is ±100% of the base frequency (freq += (fm_lin / 5) * base). This enables through-zero linear FM and its classic symmetric sidebands; the frequency may pass through and below zero, running the phase backwards.
