A helper graph element that selects a particular range of
output channel of another element. The range is specified with
integers and thus cannot be determined at graph expansion time.
If this is desired, the Select UGen can be used.
Usually the graph element operator out along with
a standard Scala Range argument can be used
instead of explicitly writing ChannelRangeProxy. Thus
elem out (0 until 4) selects the first four channels and is
equivalent to ChannelRangeProxy(elem, from = 0, until = 4, step = 1).
Behind the scene, ChannelProxy instances are created, thus
ChannelRangeProxy(x, a, b) is the same as
(a until b).map(ChannelProxy(x, _)): GE.
Because ScalaCollider allows late-expanding graph elements, we have no direct way to get some array of a UGen's outputs.
- Value Params
- elem
a multi-channel element from which to select channels.
- from
the first index (inclusive) of the channel range, counting from zero.
- step
the increment from index to index in the range. A value of one means all channels from
fromuntiluntilwill be selected. A value of two means, every second channel will be skipped. A negative value can be used to count down from high to low indices.- until
the end index (exclusive) of the channel range, counting from zero.
