[PD] Inverse bandpass filter
Is there a simple way to make [bp~] or [vcf~] have an inverse function? To filter out, rather than pass a changing frequency value. Is the easiest way to do this with a combination of [lop~] and [hip~]? ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
Re: [PD] Keeping Number box's
Also [metro] will default to the creation argument, so you can just have it be [metro 32] with nothing going into the right inlet and it'll use that value.

Re: [PD] Keeping Number box's
If you know exactly what you want the values to be before you open the patch you can replace the number atoms with messages, ie [32( instead of an atom. And then just send them a [loadbang] to initialize whatever they're going into... On Mon, Apr 14, 2014 at 1:47 PM, kate sweeney wrote: > Hello, > > I am using GEM to create a graphical design video.

Re: [PD] GEM patch
I don't think you need to send [gemhead] to the toggle--I'm pretty sure this configuration just doesn't do anything (as far as the toggle goes). If you just need to start the [metro] you can start it with a bang using a [t b f] from the number atom that sets the [metro] speed. If you need to toggle [metro] in accordance with whatever is happening in a GEM window I'd suggest sending the trigger to the toggle and to the GEM components separately. Does that make sense?
