Function numeric_per_sample 

pub fn numeric_per_sample<I: IntoIterator<Item = PiecewiseLinearCurvePoint, IntoIter: Clone>>(
    state: NumericBufferState<I>,
) -> impl Iterator<Item = f32> + Clone

Converts a NumericBufferState into a per-sample iterator.

This provides the value of the parameter at each sample in the buffer. Note: for constant values, this returns an infinite iterator.
