Re: [PD] smooth random numbers
Roman, are you using MIDI in theory or real life? Jitter is MIDI's alias name. In practice MIDI data is being reduced as much as possible to avoid overloading the MIDI bus and in return causing serious timing problems or even missing data. Since I would not expect this signal to be the only one through the MIDI interface I would actually reduce the data on fast changes even drastically more. All (decent) MIDI receiving devices interpolate between the values in order to avoid zipper noise. I see your point - in fact I had the same thought that you had at first! I dropped it right away. Working on a daily basis with MIDI I know that this is a waste of time. Actually: I would add a [speedlim 5] to reduce data further and you still wouldn't hear anything unusual. That reminds me a little of people asking for 14-bit pitchbend. It would take about 11 seconds to move the pitchbend wheel on a keyboard from the bottom to the top. Even a 7-bit pitchbend takes more that 80 ms sending all values. It's impossible to play music with a precise timing like this! In practice a very fast volume change going from 0 - 127 usually gets reduced to 3-5 numbers in order to allow additional controllers like pitchbend and aftertouch to be sent at the same time and still keep the note on jitter within a range of maybe 3-8 ms (plus the jitter of the interface itself). And BTW - why would random need extra precision? Doesn't the word random say it all? Another neglected thing is the curve that the data change should have. That would obviously require some extra calculation. I don't remember reading anything about that in the original posting, though.

Re: [PD] libpd separating gui from core
So let's just take a concrete example: $@ syntax. It is a dollarsign variable in Pd-l2ork (and maybe in Pd-extended-- can't remember) and it expands to the incoming arguments. In an object box this expands to the arguments of the parent. The code for this feature affects Pd's message parser, which is in the core. This is just an example-- there is a whole category of features which require changes to core code like this one. If you have a description of a democratic development process that can implement such a feature by wrapping Pd Vanilla in a GUI wrapper, document how it works, and if it's maintainable I'll help you implement it. -Jonathan On Monday, February 24, 2014 1:56 PM, Ivica Ico Bukvic i...@vt.edu wrote: From:Dan Wilcox [mailto:danomat...@gmail.com] Sent: Monday, February 24, 2014 11:34 AM To: Ivica Bukvic Cc: Jonathan Wilkes; pd-list@iem.at List; Peter Brinkmann Subject: Re: [PD] libpd separating gui from core On Mon, Feb 24, 2014 at 12:29 AM, Ivica Bukvic i...@vt.edu wrote: On Sun, Feb 23, 2014 at 11:04 PM, Dan Wilcox danomat...@gmail.com wrote: I consider that a sad thing.

Re: [PD] libpd separating gui from core
Exactly. If we can build a list of things that should/could be in the core, then we have a starting place to see if there is a way to work into into either vanilla or a wrapper like libpd. As we do in OpenFrameworks, I've started a PiratePad for general ideas/requirements.

Hm, for some reason none of the two works. Neither with pix_snap, nor without but sending [file name 99( to [pix_write] (replacing name with whatever name I wanna give to the file).

Re: [PD] libpd separating gui from core
I think Miller's puredata is awesome. more than 20 years ago I wrote my own assembly routines as well as c++ for an analog devices 32 ch board for waterplant control software , but ended up using the factory drivers instead when they came out for this software http://home.comcast.net/~patslabtech/Applications/seatbelt_testing.html. reminds me more of reaktor than puredata. I have a hard time comprehending reaktor stuff but things make so much more since using pd. I ought do dig into the programming part of pd . I read a lot of the code and it's kinda starting to sink in how to write an external, it's not quite like on the tip of my toungue yet though.

Let's just focus on a single feature-- $@-- and assume that there is widespread desire for such a feature by most Pd users. How do we put this feature into a wrapper like libpd? The only thing I can think of is as part of a patch set that get applied to core Vanilla, and that's hard to maintain. As for working stuff into Vanilla-- that's Miller's personal version of Pd, and I've never once seen him state that it's the reference client, or that it's at the top of any hierarchy. All I've seen is passive-aggressive statements from other devs on this list who say, You'll have to ask Miller if you want to get 'whatever' in Vanilla, when I ask about the kind of issues you're talking about. Of course I can't be certain but I'd guess that style of non-development is probably one of the biggest sources of your frustration. But I really will help you implement whatever it is you think improves sustainable development for Pd. I really, really don't want to extract patches from the 1000+ commits in Pd-l2ork (granted the core/non-graphical changes would be fewer), but I'll help you do it if that's the path you want to take. -Jonathan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/ listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

$150.
