Yes, it does reflect the number of channels. For example:
(
{SinOsc.ar}.scope
)
// 1 channel in scope
(
{SinOsc.ar!2}.scope
)
// 2 channels in scope
(
{SinOsc.ar!3}.scope
)
// 3 channels in scope and so forth
And yes, the default fade time is 0.05. There are rather a lot of typos and little errors in the help files. There are examples with ugen graph functions that have arguments that do nothing. The Pen class help file has an extensive documentation of methods that don’t even work/aren’t implemented (transparency layers? why is this so well documented if it doesn’t actually work?)
It would be nice if these issues could be fixed and I’d be happy to help with this, but I’m not sure how this is handled.
