Function enum_per_sample 

pub fn enum_per_sample<I: IntoIterator<Item = TimedValue<u32>, IntoIter: Clone>>(
    state: EnumBufferState<I>,
) -> impl Iterator<Item = u32> + Clone

Converts an EnumBufferState 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.
