phasor_bank_state()

MAYAFLUX_API std::vector< double > MayaFlux::Kinesis::Discrete::phasor_bank_state	(	std::span< const double >	increments,
		std::span< const double >	scales = {},
		std::span< const double >	am_increments = {},
		std::span< const double >	phases = {},
		std::span< const double >	am_phases = {}
	)

Builds the array phasor_bank reads and writes.

Parameters

increments	Radians per sample of each partial; sets the count
scales	Amplitude of each partial; missing entries are 1
am_increments	Radians per sample of each partial's slow amplitude swell; missing entries are 0, which holds the swell at one half
phases	Starting phase of each partial; missing entries are 0
am_phases	Starting phase of each swell; missing entries are 0

Layout: [N, increments, scales, am_increments, phases, am_phases], each column N long. Whether partials start together or apart is only what the phase columns hold.
