signal and message inlets
by Thomas Grill 19 Mar '02

19 Mar '02

Hi list, is it possible (for an external) to have a signal and messages going into the same inlet? (apart from the leftmost) I tried some things with proxy objects but an inlet seems to have either a "signal" or message symbol specification, right? thanks! Thomas

Arrays
by Marcus Flanagan 19 Mar '02

19 Mar '02

Hello, 1) Ok, I can put info into an array, but how do I get it out and make it do something. If I put the 8 notes of a number of different scales into an array and want to retrieve them at different times..how do I do that? E.G..sometimes I may want the minor scale...sometimes I may want the major scale... I figured out how to read and write to files...but the arrays seem useless...is it possible to bang an array and connect it to something like the "noteout" object so that it plays it contents? 2) If I store values of chord notes in an array..how can I compare these values to the ones that are coming in from the "notein" object(using the "poly" object to get all notes from "notein"). I want to recognise chords input from the MIDI keyboard and get PD to play a little melody over them, somehow by using arrays. I've been looking at them all weekend and still I'm no closer to getting anywhere! Somebody must understand me! _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

3 patches
by João Miguel Pais 18 Mar '02

18 Mar '02

Dear list, I would like to present to your consideration a set of patches I've been working on. There are 3: -Sampler unit (stores up to 6 mono samples, played only at normal speed) -Synthesis unit (sine, sawtooth, noise, fourier synthesis, waveshaping, classic fm - from the reference folder) - Effects processing unit (delay, filters, am), which works with the previous two as sources Every module can also record and has a (simple) fft window. It is not a finished object (and probably will never be), but a work in progress, which implements the things that I remembered so far. It's jsut supposed to be a small utility for quick browsing. It was made on win xp, and uses only standard objects, so I guess it should work everywhere. One other thing, it is in (very bad) german. Every critic/suggestion/advice is welcome. You can find it at http://home.arcor.de/jmmmp/. If possible, I would enjoy some guidances on these lines: - how to make a "horizontal zoom" on the fft windows (dinamic change of block~ size?) - how to record a stereo file from two separate arrays (or x-channel from x arrays) - der deutsch verbessern Hope you have fun, João Miguel Pais

expr object / power operator
by Ivan Averintsev 18 Mar '02

18 Mar '02

Hi list, is the power operator implemented in the expr object? "^" won't do the job... If it isn't, are there any other possibilities to compute power-values within pd without writing/modifying an external? -- pooz

Many clips in Gem, best way to deal?
by Ben Bogart - FMPM/F1999 18 Mar '02

18 Mar '02

Hello all, we're having a performance (opening) in 10 days and have run into a little problem. We are using gem to call up and play a base of movie clips (about 150 each at 512x256 cinepak) I did a test with 15 movie clips and came to an awful realization (under windows 2k): after 4 hours of running everything looked find in the window, video still playing fast and nice. Then I looked at the system resources. PD was using 500MB RAM and 1.5GB Virtual Memory. After 5 hours PD died(quit). So this thing is supposed to run for at least 5 hours, at best 3 days straight. The way the patch works is that it sending a "open" message to a single pix_movie at a metro's whim. There are 15 such "open" messages called randomly. Is PD using so much memory because it keeps each clip in memory after the pix_movie has opened another one? Even when it loads the same clip twice it seems to be keeping multiple coppies in memory? So the question is, what do I do about it? Whats the most efficient way to run many video clips on one primitive object (rectangle) Is there a way of loading all the clips into memory first and then calling each one out of memory when needed? Or is there a way of clearing the buffer everytime a new clip is loaded? I'm trying now to get gem .87 test2 to work on linux, just to keep the thing from crashing... (I have 640MB RAM and 500MB swap space for linux) any pointers would be appriciated... I'm now in the hunt for lmpeg3 can't find it with apt, any quick suggestions? Thanks! Ben+ekran B. Bogart ---------

problem with arrays in 0.35, test 11
by oliver 18 Mar '02

18 Mar '02

hi list, hi miller there's a little "downgrade" in pd 0.35,test11 (linux) as far as array-convenience is concerned: if you want to draw in an array, now you can't just click into the graph and drag with the mouse, but you have to start drawing from an already existing array-line. this makes drawing a very un-handy thing. is it possible to restore the old graph behaviour ? ciao oliver

state and gui
by CK 18 Mar '02

18 Mar '02

hi, after a private conversation with guenther it looks like the (IMO _very_ useful) state object is dying, is there anyone out there already familiar with the gui internals willing to take the challenge and write a state object that saves the current state of all (including the somewhat newer) the gui objects ? regards, x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

RE: [PD] Windows compiling and cross platform buddies
by mark 18 Mar '02

18 Mar '02

> Maybe we can call it a "project" and put it on sourceforge. Whilst I don't have a problem with this - this is going to have the same issues for non devlopers. What windows people need is a nice clean release from a clear source. They are not used to thinking about source versions etc. BTW I am not denigrating Windows users - I am just being realistic about what they are used to. PD is a tool for making music - I am lucky 'cos I am a programmer but for most people all the programing stuff is a little bit off putting. I think PD is a great program and as many people as possible should have access to it. mark

RE: [PD] me too compiling help

If you do "Open workspace" and then choose the makefile in VC you can use its compile tools (F7 to compile F4 - next error - very quick) but you need to edit the makefile to make changes to the project mark > -----Original Message----- > From: Nick Fells [mailto:nick@music.gla.ac.uk] > Sent: 18 March 2002 10:13 > To: sme > Cc: pd-list(a)iem.kug.ac.at > Subject: Re: [PD] me too compiling help > > > Dear Marius, > > If it's any help, when I tried with VC, the whole front end business > kind of got in the way - I found it easier just to use nmake from the > command line, in the end.... > > Nick > > > sme wrote: > > > > hi > > spent the weekend by trying to find out by myself, how to > compile externals > > for pd, searched also in the list and the externals-howto, > but no chance, > > ... i did not use the VC++ before, so everything is new for > me, still i > > would like go get this working. i have only a german > version 5.0. when i try > > to (re-)compile the zexy-externals the compiler shows up a > message.
