How do I bypass a filter?

How do I bypass a filter? For example...

hi

every unitgenerator has some basic functionality.
(inherited by the basic ugen class).

the parameter .op(int) controls the behaviour of the ugen:

op(int) (of type int): set/get operation at the UGen. Values:
0 : stop - always output 0
1 : normal operation, add all inputs (default)
2 : normal operation, subtract inputs starting from the earliest connected
3 : normal operation, multiply all inputs
4 : normal operation, divide inputs starting from the earlist connected
-1 : passthru - all inputs to the ugen are summed and passed directly to output

i copy/pasted this directly from the chuck homepage here:

Thanks very much!

Don't feel too hard, the documentation is scattered a little so things can be hard to find.

As for changing the filter (as opposed to bypassing it), you could set it up like this;


SndBuf buf => BPF filter => dac;
LPF filter2 => dac;

then, any time you'd like to switch you can disconect the buf from the BPF filter by "unchucking" it from there, then connecting it to the LPF.

from memory; the unchuck operator is like this;

SndBuf buf =< BPF filter;

But that one doesn't seem to be on that page.

Another different idea i have in mind now:

For a smoother switching..
i think an Enveloping would be able to smooth things up.
