@section{description}
keeps a reference to a link::Classes/Pbind:: in which single keys can be replaced. It plays on when the old stream ended and a new stream is set and schedules the changes to the beat.
@section{ClassMethods}
@section{method}
new
create a new instance of PbindProxy with the given patternpairs
@section{InstanceMethods}
@section{method}
source
returns the wrapper for the Pbind
@section{method}
set
set the given patternpairs.
@section{method}
at
return a pattern at that key. this can be used to set quant value individually, so different elementary patterns can be quantized differently.
@racketblock[
x.at(\freq).quant = 2;
::
]
@section{method}
quant
set the quant of all elementary patterns, or return the quant value of the source pattern.
