Struct SamplePlayerNode 

pub struct SamplePlayerNode<T: Transcendental, const BUF_SIZE: usize> { /* private fields */ }

Sample-playback source node with stereo support.

Parameters (all automatable via patchbay)

Name	Type	Range	Description
"gate"	Bool	–	Start / stop playback
"rate"	Float	0.0–4.0	Playback speed ratio
"loop_mode"	Choice	oneshot/forward/pingpong	Loop behaviour
"start"	Float	0.0–1.0	Loop start (normalised)
"end"	Float	0.0–1.0	Loop end (normalised)
"amplitude"	Float	0.0–1.0	Output gain
"interpolation"	Choice	linear/cubic	Interpolation mode
"position"	Float	0.0–1.0	Current position (read-only)

Output ports

• Port 0: left channel
• Port 1: right channel (only present when a stereo sample is loaded)
