Detailed Description

template<typename Exciter, typename Load, uint16_t MaxPeriod = 1536>
class sbl::dsp::pm::StringBase< Exciter, Load, MaxPeriod >

Template Parameters

Exciter	what plays the string (contracts.hpp: Exciter)
Load	what end b terminates on (contracts.hpp: Load)
MaxPeriod	longest loop in samples, which sets the lowest pitch. The default covers C1 at 48 kHz (a 1469-sample period); each of the two segments gets a buffer this size. The widget owns its buffers: it is the black box, the loop inside it is not.

Note: All public methods are ISR-safe — bounded computation, no I/O.

void sbl::dsp::pm::StringBase< Exciter, Load, MaxPeriod >::set_position_su ( float su )

inline

Where the exciter sits along the string.

0 is near an end, 1 is the middle. Positions mirror about the middle, so this spans the distinct ones. Near an end the string locks onto upper modes — an octave or more up — which is the real instrument's behaviour, not a fault (AP-032 Phase 1 finding 3). Smoothed.

inline

What is heard: 0 the load, 1 the bare string, a crossfade between.

Smoothed and ramped across each block, so turning it never steps. It changes the output only, not the string. Without the load it has no effect.
