tabread4~ help
by briencrean＠eircom.net 01 Aug '06

01 Aug '06

Hi all, Im struggling with understanding how the tabread4~ object works. Im still pretty new to pd. I have read through the examples and the documentation and searched through some of the archive but I still dont fully get it! I want to understand this object and also use it (or another object) to apply real-time effects to samples and use it as lookup table. The problems I have are: 1.How do you know what size to specify for the array that tabread4~ will read from for different length soundfiles? -Do I always use the output from soundfiler as the length of the array - 2? 2.Again regarding the length, taking the example B07.sampler.pd, what happens if the length of the sound file changes? Do I need to change the value I am multiplying by or is that dependant on the sampling rate of the audio file? -For example I changed the array range 0 to 62078 in the 1st attached patch for the same sound file (voice.wav) which is the full length of that file (1 second), it seems to sound ok when the number box is dragged Also I experimented with attaching a phasor object to the inlet, 2nd patch attached, to cycle through at different speeds. Even though when viewing the voice.wav file in media player it is a second long but when using the line object I need to specify a message of 62709 in 1400 milli seconds for it to sound right? Sorry to barrage you guys with so many questions. Thanks guys!

Percolate for PD+win32
by David Powers 01 Aug '06

01 Aug '06

Hello, Okay maybe this is a sensitive topic, but surely SOMEONE has Olaf's port of Percolate for win32 around still. If I can't get it, I will have to send OSC from PD to Max or ChucK, which just seems dumb. If anyone has this could they email me??? I really need this for an experimental opera I'm doing where I want to use PD. ~David

a fast way for "table to message" (and a GEM based oscilloscope)
by sokratesla 01 Aug '06

01 Aug '06

# hi everybody! # I started to toy with GEM and found it extremely useful and entertaining. # I know, its a 3D utility, based on OpenGL, but I wanted to use its graphical abilities for 2D animation (using [pix_set]) # I tried to make an oscilloscope, which, basically, is a texture mapped on a rectangle. I'm preparing a table which includes the message to sent pix_set, and this preparation must be executed 20 per second (for 20 fps) # There is a [list-dump] abstraction in the list-abs library, which converts the table to a message. But it runs too slow when the table length is relatively high (for getting a 256x128 resolution for oscilloscope the table must be 32768 numbers long and it takes 10 seconds or so, to finish that job for a single frame, in 1.83 MHz CPU) # I've attached a 256x8 resolutioned oscilloscope, it runs good. And I'm asking for a fast way for dumping a table to a list. # Creative days for everyone! -ugur guney-

Key-repeat makes keyboard-pianokeys impossible?
by Luke Iannini (pd) 01 Aug '06

01 Aug '06

Hi all, I am being ushered to sleep so I have little time to explain this in detail, but hopefully that just means you'll all be spared tedious detail that would obfuscate the issue : ). I'm trying to build a simple computer-key piano such as the one in Apple's GarageBand using the [key] object, and I'd like to be able to hold the keys down rather than have single shot. Key helpfully provides 0/1 notifiers for keydown and keyup - but OS X's built-in key-repeat makes it infinitely retrigger the keypress when held. The GarageBand keyboard does not do this, so I was hoping someone might have some ideas on getting around this so I don't have to pull out my (rather unportable) midi-controller when I'm patching on the road. Thanks!

Self sizing GOP sequencer
by Chris McCormick 01 Aug '06

01 Aug '06

Hi, In light of the canvas resizing message that IOhannes sent through, I've modified my variable sequencer abstraction to resize itself depending on how many beats you initialise it with. I also added a help file. http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-varseq.pd http://mccormick.cx/viewcvs/*checkout*/s-abstractions/s-varseq-help.pd Please note, the deprecated external [namecanvas] is required! Have fun. Best, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

arrays on 64 bit (2)
by geiger 01 Aug '06

01 Aug '06

Hi, Here is another version of the patch, this one applies cleanly against version 0.39-2 (The other one was against the HEAD version of pd CVS). Günter PS: For those who wonder, these are not pd patches, but source code patches. They are meant for developers.

[flext] Inheriting access to variables declared once in a library
by Christian Frisson 01 Aug '06

01 Aug '06

Hi, I'm currently using flext to develop a library of externals itself wrapping another C++ library. On the latter library, some setup classes have to be instanciated once only in a whole application. What's the way to benefit from inheritance in order to: - declare instances of those setup classes only in the base flext class of the library in order to create each only once; - share access with externals, being flext inherited classes of the base class? As I'm a poor C++ coder, the only ugly way I've yet found to circumvent this is declaring instances of those setup classes outside flext classes, statically. But for sure those variable won't get deleted and Pd sends a "read memory" error message when it's being closed... Any idea? Thanks, Christian

bang and zero?
by Oded Ben-Tal 01 Aug '06

01 Aug '06

I noticed that sometimes a bang message gets converted to zero but not always. for example if I send a bang to a number object it dosn't change anything, but if I pass the bang through a pipe object first it changes the number to zero. Does anyone know why? thanks Oded -- ___________________________________________________ Oded Ben-Tal http://ccrma.stanford.edu/~oded oded(a)ccrma.stanford.edu

PD markov object
by c.m.bryan 01 Aug '06

01 Aug '06

Hello all, I'm needing some compilation help with the markov object I found here: http://icem-www.folkwang-hochschule.de/~finnendahl/pd.html (bottom of the page) I'm using it on linux, but I can't get it to compile on win32. Alternatively, if anyone knows of an alternative object, that would be just as useful. Thanks in advance, - Chris Bryan
