loading libraries in OS X?
by David Kendall 30 Apr '04

30 Apr '04

Hello Everyone I am in the process of switching computers, and operating systems, from windows 98 to mac OS X, and I am trying to load all of my patches that I wrote in windows to my new computer. I had no trouble installing pd on OS X, but now I can't figure out how to load libraries (percolate, especially!) on to Pd. I know how to do it on the DOS command line. Is the syntax the same? i.e.: pd -lib percolate ........or whatever... It seems like I am missing a pretty simple solution, though I would like to have Pd for OS X running as soon as possible, so any help would be greatly appreciated. Thanks! David

RE: [PD] Is there a 'switch' object?
by Matthew Allen 29 Apr '04

29 Apr '04

I will have to take a look at this patch. What are the advantages of using [sigzero~] (which I am guessing bangs the output when the signal gets to zero) over something like [threshold~] which gives you control over low value bang and high value bang, along with jitter control? m. > -----Original Message----- > From: pd-list-admin(a)iem.at [mailto:pd-list-admin@iem.at] On Behalf Of > matthew jones > Sent: Thursday, April 29, 2004 7:05 AM > To: PD-List; Eric Skogen > Subject: Re: [PD] Is there a 'switch' object? > > > somewhere i remember seeing an abstraction which would detect when the > > inlet~ level is quiet and [switch~] off DSP at that time, and turn it on > > again when it gets more level ... i thought it was a good idea, as long > > as there's some envelope to avoid clicks. can't find the abstraction now > > though... > > it's in the sigzero~ help file (zexy) > > Matt > > -=-=-=-=-=-=-=-=-=-=-=-=- > http://www.loopit.org/ > -=-=-=-=-=-=-=-=-=-=-=-=- > > _______________________________________________ > PD-list mailing list > PD-list(a)iem.at > to manage your subscription (including un-subscription) see > http://iem.at/cgi-bin/mailman/listinfo/pd-list > > > _________________________________________________ > Scanned on 29 Apr 2004 14:11:13 > Scanning by http://erado.com _________________________________________________ Scanned on 29 Apr 2004 16:10:38 Scanning by http://erado.com

I use this technique quite a bit for things like volume envelopes and filters. .matt _________________________________________________ Scanned on 29 Apr 2004 16:06:02 Scanning by http://erado.com

Is there a 'switch' object?
by acabrera＠teleset.com.co 29 Apr '04

29 Apr '04

Hi all, I'm wondering if an object exists that can act as a 'switch'. What I mean is that when it is in one state, the signal flow continues in one direction and when in the other it goes in another direction, basically deactivating the other branch. What I want to do is split a gem list in two, so when the switch is in one state one type of processing is done, and another type of process is done when the switch is in another state. All this to save cpu, since both processes could be placed inline, but would consume too much cpu. I'm thinking specifically of live video processing. Is there an object to do this, or can anyone think of a way to do this? Thanks all!

RE: [PD] GEM + Logitech Quickcam = no textures

Maybe this will shed some light. Before the big kernel compile snafu, PDP couldn't grab frames either.
