(1) Does the fact that OSCroute, sendOSC, and dumpOSC are deprecated mean that they actually don't work, or do they still work?

The mrpeach OSC object classes are more low level, but also more flexible, less buggy and actively maintained (2) Where can I get a version of Pd-extended that includes the new, preferred OSC objects? They most likely are included in your version already. Pd-extended does _not_ load _all_ libraries by default, which is IMHO a good thing. You can easily load a library from your patch by putting a [import mrpeach] in it. (3) If there is no such version, how exactly would I go about incorporating them in 0.42.5? Not necessary. (4) What sort of patching will I need to do in order to connect the mrpeach objects with the [udp] objects after I've installed them, and where is this patching documented? Check the helpfiles for [packOSC] and [unpackOSC], they show how to hook up the OSC object classes with the net (udp|tcp) object classes. Sorry to be a pest about this. Right at the moment I'm trying to document the usage of OSC to let Pd communicate with Csound. Andres Cabrera's very nice tutorial video (on YouTube) uses the old Pd objects. I'd like to use the new objects in the tutorial I'm writing, but I can hardly do so when I don't understand where the objects are or how to install them. Cool. I strongly recommend to use the mrpeach OSC classes. BTW: you find a lot of info in the mailing list archives about this topic.

Well, if you wanted to really use SSE in that case, it would be
appropriate to process 4 interleaved signals at once, or at least two.
Btw, if you want something fun, consider :
a+b = (a^b) + ((ab)1)
that is, addition of ints can be split into a variable number of steps :
int add (int a, int b) {return b ? add(a^b,(ab)1) : a;}
where the number of steps is the number of consecutive carries (of ones)
it has to do. (how many average steps does that make, for random ints ?)
I've always found this formula fascinating, but I'm still waiting for the
occasion to make use of it, 15 years later :)

Re: [PD] ternary counting
On Thu, 8 Sep 2011, Andy Farnell wrote: Try a [div] [mod] chain Four digits base 3 would be Also, to have the counting itself in base 3, chain counters that count 0,1,2,0,1,2,0,1,2,... in which each counter adds a 1 to the counter on the left whenever it goes from 2 to 0. This makes a sequence like 00 01 02 10 11 12 20 21 22 as Tim wants. This can be converted back to another number format using the opposite of what Andy showed : take D3 multiply by 3 add D2 multiply by 3 add D1 multiply by 3 add D0 But the output of this, and the input of Andy's, is not necessarily in base 10. It is actually in the base that [mod], [div], [*] and [+] are in, and in the case of Pd, that's in binary. libc's printf() function does something very much like what Andy said, to convert its binary ints to decimal ascii. The differences are that it says 10 instead of 3, and it adds 48 to each digit because codes 48 through 57 represent the 10 digits. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Adding or '' or `` quotes means some kind of backwards incompatibility, since '` are currently all valid characters to have in a symbol. Another easy option would be to use I think this would be made much easier if the symbol selector forced the message to be a symbol, then you could do: [symbol /home/hans/My Documents( [symbol I like lots of\ \ \ \ \ spaces( [symbol commas\, in symbols( [symbol semi-colon\; in symbols( [symbol \43( [symbol \-21343( [symbol \-0.2e59( Then you'd only need the \ when its in other places, like: [route \43] And last but least, and its already in there: [symbol \43( [symbol \-21343( [symbol \-0.2e59( Anything that just \ couldn't cover?

But what I am proposing has to do with selectors, not symbol messages. Problem: convert from symbol-atom to float-atom Proposal: if a selector happens to be in a form that can be interpreted by the naked eye as a valid Pd float, and the object receiving the message has a float method (and no anything method), then send a float to the object. [r infinite-expressivity] | [1( - float | [makefilename %d] -- converted to symbol message (and the message arg is convert to a symbol-atom) | [list trim] -- now we have a message with the selector 1 and no arguments | [route float] -- seriously, it's a symbol-atom, not a float | + | [float] -- my proposal: give [float] a float-atom instead of a symbol-atom in this case | [route float] | [set $1, bang( | [s infinite-expressivity] But if there were a really nice quoting mechanism, that would probably be much clearer. Yes, I agree that [float] and [symbol] should also do conversions. A good example would be Python's str() and float(). etc. A quoting mechanism would also help. We could probably get away with only \. For example, \ for spaces, like: [symbol /home/hans/My\ Documents( [symbol I\ like\ lots\ of\ \ \ \ \ spaces( [symbol commas\,\ in\ symbols( [symbol semi-colon\;\ in\ symbols( That looks really ugly to me. What's wrong with quotes? The nice part would be that it would only add one special character, \, which is currently not allowed anyway. Adding or '' or `` quotes means some kind of backwards incompatibility, since '` are currently all valid characters to have in a symbol. Another easy option would be to use I think this would be made much easier if the symbol selector forced the message to be a symbol, then you could do: [symbol /home/hans/My Documents( [symbol I like lots of\ \ \ \ \ spaces( [symbol commas\, in symbols( [symbol semi-colon\; in symbols( [symbol \43( [symbol \-21343( [symbol \-0.2e59( Then you'd only need the \ when its in other places, like: [route \43] And last but least, and its already in there: [symbol \43( [symbol \-21343( [symbol \-0.2e59( Anything that just \ couldn't cover? [openpanel] - outputs /home/hans/My documents | [set symbol $1( | [ ( -- What's printed here? ...My

Yes, that sounds like the appropriate thing to do with Pd.
After a JSON object is decoded, I output a bang on a second outlet, and
therefore can distinguish between two objects in short succession.
Yes, either that or an 'end' message on the first inlet, but what you
did is more usual.
Here is what I came up for arrays and nested objects:
If they come up inside an object, they are output as the symbol that
they are. The JSON string can then be parsed by another instance of
[json-decode] (or send it recursively to the same object).
Arrays as symbols themselves are parsed like several seperate objects.
Here is an example:
Consider the JSON string
{id: 1, name: Residuum,member: {first-name: Thomas,
last-name: Mayer}, albums: [{year: 2011, name: Der
Diskokeller des Grauens}, {year: 2009, name: Schrei-Funk-Flaeche}]}
When parsed with an instance of [json-decode] this will output
list id 1
list name Residuum
list member {first-name: Thomas, last-name: Mayer}
list albums [{year: 2011, name: Der Diskokeller des Grauens},
{year: 2009, name: Schrei-Funk-Flaeche}]
followed by a bang on the second outlet.
When parsing the array for albums, i.e.
[{year: 2011, name: Der Diskokeller des Grauens}, {year: 2009,
name: Schrei-Funk-Flaeche}]
This will output:
list year 2011
list name Der\ Diskokeller\ des\ Grauens
bang on second outlet
list year 2009
list name Schrei-Funk-Flaeche
bang on second outlet

Thanks for reading,
Thomas

OK, I got it! Downloading the files didn't work (at least not on my Windows computer) but copying the content into a bunch of text files and renaming them did. I'll take a look at it later to see if the problems with the 1st and 2nd digital input as well as my problems with inputs 10 - 13 are gone.
