controlling voices in svf~

Hello,

I have a large patch that is using multiple copies of svf~. Does anyone know if you can silence 3 out of the 4 outputs of this object via messages?

Thanks,
Chad

Besides sending 0 or 1 messages to gate~ (or toggle + *~, as in the svf~ help patch) objects placed after the oulets of svf~, I would opt for using matrix~. You can have one matrix~ after each instance of svf~, or a single matrix for the patch. With a single matrix~ object, you could use a single message to set gain levels and ramp times for every svf~ outlet in your patch!

If you’re only using one of the outputs at a time, you could just use
biquad~. (which can be any of the filters that svf~ creates)
Filtergraph or filtercoeff~ can change the type of filter. This will
definitely be more CPU efficient.

Alternatively, you could use a matrix~ 4 1 0. connected to the outputs
and mute/unmute as necessary. (blend is interesting…)

Hello folks,

We are happy to announce that we’ve succefully build an external which
gives the real total cpu usage of your machine (in percent), and the
memory usage (percent and Mo used).

Currently, this object is for Windows only (2000/NT/XP) and is in its
last testing phase. We’re working on OSX & UB versions and it will take
some time because we have to write a complete new code for each machine.

When using Max, there’s often more processing used for UI than dsp, and
with several applications running on the same machine, you never now
what’s really happening. Soon you will.

This could prevent max crashes or hanging up while in live performances
at the Madison Square Garden. And will show Manuel Poletti’s troubles
with sfplay~ ;-)

Object will be available when Macintosh ports will be build, and will be
packed in a library containing tools of this kind.

best regards

f.e + m.o

Thanks for the tips with using Matrix, I’ll check that out.

I’ve thought about using biquad~ and other filter objects… svf~ sounds better at higher resonances…at least to me…

A few objects I just remembered that I could use for this:

begin~

or

mute~
