fundamental hot/cold midi question
by Atte André Jensen 29 Sep '07

29 Sep '07

Hi So I made to externals, [arp] (arpeggiator) and [legato] (legato monophonic midi module). My idea for both of them to be insertable "in a midi stream" for instance just after [notein], so they both have (amongst other things) a note inlet (leftmost, hot) and velocity (second to the left, cold). They both worked fine by themselves, but one of my tests for [arp] show a problem: when it's note and velocity outlets were connected to the corresponding inlets of legato, legato would miss some noteoff's (resulting in hanging notes). After some debugging I the hot/cold inlet thing came to mind. It turned out that in the code of [arp] I had outputted the note value (just) before the velocity, and if I reversed that sending order, [legato] would get all it's noteoffs and the hanging problem is gone. Fine. I thought I had it all sorted out, it must have been because [arp] was sending its note first. Since the note outlet was connected to the hot note-inlet of [legato], legato would be triggered of the note and look at the velocity outlet, where [arp] hadn't yet made anything available. So I thought, let's go through [legato] and in a similar fashion send velocities before notes. However that didn't work, there were no sound, probably because somewhere in the midi stream noteon's were thrown away. Right now I'm pretty confused. What did I miss? In retrospect, it seems very odd to me that switching the lines sending velocity ad note in arp would have any effect. I would expect those to lines to happen "simultaneously" at least from interconnected pd-objects point of view. If someone could enlighten me, I'd be most happy :-) -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://atte.dk/compositions

[Gem] pix_texture switching not working
by Thomas Mayer 28 Sep '07

28 Sep '07

Hello, I try to switch between [pix_film] and [pix_image] using values from a hradio. A value of 0 should use the film, 1 the picture. I'm using the following patch: [gemhead] [sel 0 1] [gemhead] | |\ |\ | [pix_film] | \ | \ [pix_image image_file] | [1([0([0([1( | | / \ / \ | [spigot] [spigot] \ / \ / [pix_texture] | After using [pix_film] via a value of 0, setting the value to 1 does not use [pix_image] for [pix_texture], but only stops the film being played and then only a static image of the /film/ is shown, but not the picture. Using [gemhead 40] to the right and switching between the two [gemhead]s for rendering does not solve that problem. I am using pd-extended 0.39.3-rc5 for Debian stable. cu Thomas -- "Prisons are needed only to provide the illusion that courts and police are effective. They're a kind of job insurance."

[PD-announce] [nsend] and [nreceive] 1.0 release
by Luke Iannini (pd) 28 Sep '07

28 Sep '07

Here's a to my knowledge completed version of nsend and nreceive. Improvements: Handling of incomplete or missing arguments Both nsend and nreceive now have an inlet for reassigning their symbol (like vanilla 0.40 send, and unlike 0.40 receive. Since nreceive will default to regular behavior with no "multiple" arg, it can be used to remedy that) cheers Luke _______________________________________________ PD-announce mailing list PD-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce
