using routeOSC with dollar creation arguments
by Matteo Sisti Sette 23 Apr '10

23 Apr '10

Hi, I'm trying to create an abstraction that contains routeOSC and I want to "pass" a creation argument of the abstraction as creation argument of routeOSC, that is simply: [routeOSC $3] Now the problem is that the object doesn't create because of this error: "error: * routeOSC: float arguments are not OK." because when you are "editing" the abstraction "as a patch", $3 evaluates to 0 (i guess). Obviously I'm gonna use my abstraction with symbols as the $3 argument. Indeed if I do, the object will create. But since it doesn't when creating the abstraction, I cannot do the connections. That relates to a more general problem that is how $-arguments are managed when you "define" an abstraction, since there is no distinction in Pd between defining an abstraction and creating a patch that is not gonna be used as an abstraction. In an ideal world, such a distinction should exist imho. However usually this "issue" only prevents the abstraction from working properly when you "edit"/"define" it, and you wouldn't expect it to work; but it usually doesn't prevent you from creating it so that you can later use it. Basically, if an object can accept a symbol as a creation argument (and only a symbol), it is an error to fail to create the object if the argument is not a symbol. Instead, the object should create as if the argument was a symbol, with the number of inlets and outlets that it would have if the argument was a symbol, _and_ print an error message and refuse to work, but not to create. Now in this case there is a workaround: [loadbang] | [symbol $3] | [set $1( | [routeOSC /dummysymbol] Note that [symbol $3] is an example of object that behaves "correctly" the way [routeOSC $3] should. When you are "editing" the abstraction, $3 is 0, so [symbol $3] is just like [symbol 0]. Such [symbol 0] is not OK and you don't expect it to work: if you bang it, it outputs "symbol": [symbol] is not supposed to be created with a numeric argument. However, it doesn't fail to create. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Anbody heard about this? Are they the first to launch this kind of amp? It looks cool, although i suppose it'll be quite expensive. I wonder how good the soundcard is. http://www.orangeamps.com/features.asp?ID=163 Pierre

audio problem on OSX with a particular mixer
by rene beekman 23 Apr '10

23 Apr '10

i'm running into a strange problem with a particular mixer, a behringer dx626. I've got the headphones/lineout of my intel macbook (running os 10.6.2) connected to one of the line-ins on the mixer. audio playback through the mixer works fine from itunes or from the finder. when i switch to pd, however, audio keeps switching on and off at a rate of about 2 or 3 times a second. i've tried fiddling with the Pd settings to solve this, but have not been able to find a solution so far. i'm using portaudio, sampling rate 44100, delay 50ms, no callbacks, input and output devices are set to built-in mic & output. changing any of these settings does not make any difference. tonight i installed jack and this did solve the problem. while i'm glad i've found a solution, i hate not understanding why it works.... anyone any suggestions or pointers? :) thanks rene

installation / configuration problem? getting od to make noise
by Bernhard Garnicnig 23 Apr '10

23 Apr '10

Dear pd users, since several weeks I'm stuck with a Mac Mini [1] on which I just cannot get pd (0.42-5 and 0.41.4-extended using both portaudio and Jack on Mac OS 10.5.8 and now 10.6) to output any sound when running testtone.pd. Yes, compute audio is enabled ;-) I've gotten pd to run just fine on other Mac and Windows based machines, but I seem to be unlucky with this particular one. Is there any chance someone else ever had a similar problem, or anyone has any idea on how to debug this? I'm out of ideas. Let me know if you need any more information about the Any help would be much appreciated!

External to get boxes' informations
by Vilson Vieira 22 Apr '10

22 Apr '10

Guys, is there any object (or any way to create an external object) to get informations about other objects on the patch at the moment (for example, the number of inlets/outlets of one object, it's state (number, symbol, ...) and other things)? Thanks! -- Vilson Vieira vilson(a)void.cc ((( http://automata.cc ))) ((( http://musa.cc )))

oscx help patches?
by Matteo Sisti Sette 22 Apr '10

22 Apr '10

Hi, Are there help patches for dumpOSC, OSCsend, unpackOSC? If so, where can they be found? I have Pd Extended and the dll's are in the folders "mrpeach" and "oscx"; however, the help patches for the mentioned objects are not there (in oscx there's no help patch at all) thanks m. -- Matteo Sisti Sette matteosistisette(a)gmail.com http://www.matteosistisette.com

Re: [PD] length in midifile
by colet.patrice＠free.fr 22 Apr '10

22 Apr '10

It's not me that has decided there is no midi note length, it's the midi protocol creators. you have Note On for playing the note, and Note Off to stop playing the note, how would it be better? for this reason we often use [stripnote] because [makenote] sends a Note On and a Note Off (the same note with velocity zero) that's also why there is an object like [poly] that can redistribute those On and Off notes. Just read about midi protocol! ----- Mail Original ----- De: "Rory Walsh" <rorywalsh(a)ear.ie> À: "colet patrice" <colet.patrice(a)free.fr> Envoyé: Mercredi 21 Avril 2010 19h56:56 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: Re: [PD] length in midifile > there is no midi length message, only midi noteOn for begining and midi noteOff message for ending Of course there is. Unfortunately I'm not familiar with the [midifile] object, so I've know idea how to retrieve delta-time values with it. I just felt compelled to write back and confirm that midi files do of course contain timing information, how else would sequencers know when to play the notes?

A bunch of revised help patches
by Jonathan Wilkes 22 Apr '10

22 Apr '10

Hi list, I have a bunch of revised help patches from the doc folder for pd-extended, plus a little object search prototype. The zip file totals about 1 meg. Is that too big to post here? If so, where's an easy place to upload them to make them available? -Jonathan

Ha ha, not to mention the proliferation of wonderful period-instrument ensembles that use 18th- and 19th-century replicas. Some of those musicians are really, really good -- the C clarinets sound just fine in the context of Beethoven and Berlioz. One would probably not want to play the Rite of Spring solo on an 18th-century bassoon, though. In music, and I think I would argue art in general, context is key. Matt
