Re: readsf~ / soundfiler crash with lots of big files
by Stefan Turner 14 Nov '04

14 Nov '04

Hi Pete, thanks for the reply. Unfortunately they do all need to be loaded. Basically, (sorry for not explaining it too well), if you were just going to use a few readsf~ with poly in front, i.e. forget about these tables completely, you need to wait between telling readsf~ to open and telling it to start; it can't do both straight away. That's the point of the tables: they CAN start playing the very first bit (4096 samples) straight away, and that gives enough time between telling readsf~ to open and telling it to start playing. As I say it works fine for a few pitches, and I guess it is the standard approach for these types of instrument. So therefore you DO need a table per pitch: if you only had say six, then any note outside of those six could not be played instantly like this. Hope that explains it better. I think the main problem is readsf~ seems to load ALL of a big file into memory, although I only want the first 4096 samples and close it after this. When I try and have 12 of these at the same time, pd dies. Does this mean pd is incapable of working as a basic soft sampler?? Er sorry for writing another essay. I'd love to hear any ideas!

labeling buttons for [hid]
by Hans-Christoph Steiner 14 Nov '04

14 Nov '04

So I wanted to throw out an idea to see what people think. I am working on a cross-platform scheme for naming the buttons on devices like mice, joysticks, tablets, etc. Each OS has its own scheme, with some similarities. But I am making a common scheme so that patches that use [hid] will work on all platforms. Right now, I am wondering how I should label buttons. MacOS X HID Manager simply numbers the buttons, I think Windows does a similar thing since both are based on the USB HID spec. The Linux input event system uses button names, like btn_left, btn_middle (mice); btn_trigger, btn_base (joysticks); btn_a, btn_select (gamepads); btn_tool_pen, btn_stylus (tablets); with a different naming scheme for each device type. I started out just copying the Linux system outright for a number of reasons, but now I am thinking that button numbers probably make a lot more sense. Here are some advantages/disadvantages that I see: button numbers: advantages: more efficient to use floats rather than symbols much easier to implement on MacOS X patches written for buttons on one device would work for other devices (i.e. a patch written for a mouse could be triggered by the buttons of a joystick, tablet, etc.) disadvantages: user has to test the device to find the numbering scheme, rather than reading the label slightly harder to implement on GNU/Linux Any thoughts, comments, feedback, etc would be appreciated. .hc ________________________________________________________________________ ____ There is no way to peace, peace is the way. -A.J.

data structures composition/app
by Hans-Christoph Steiner 13 Nov '04

13 Nov '04

So here is the next release of the data structures patch that I have been working on. Its all loaded up with the score to a 3 1/2 minute sketch for a composition I am working on. The sample files needed are included, that's why its a 4 meg file. Eventually, I could see generalizing this patch into a sample manipulation environment. But I gotta say, data structures are fun once you learn them! Lots of potential there... http://puredata.org/Members/hans/downloads/solitude-2004-11-11.tar.bz2 zexy and probably iemlib are needed. I did this using my MacOS X distro, but it should work fine on other distros. Let me know if you can't get it running. Also, I'd love to have feedback on the composition, as it is a work in progress. .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

Re: [PD] Re: readsf~ / soundfiler crash with lots of big files
by Stefan Turner 12 Nov '04

Definitely not a stupid suggestion, thanks, I'm gonna try it tomorrow. Just thought maybe there might have been a nicer way of getting readsf~ or soundfiler not to try to allocate loads of memory for no reason...

Pure Data crashes
by " <tboulanger＠voila.fr> 12 Nov '04

12 Nov '04

Hi list ! Assuming that I have a midi keyboard (namely Oxygen8 keystation) and an internal MIDI router (Midi Yoke) I've planned to do a MIDI transformer with PD and then feed my sequencer (eg. cubase) with the transformed events : PD grabs the Kestation MIDI input, transforms MIDI messages and sends the result into MIDI Yoke 1 Cubase is set in such a maneer that it grabs what is sent out by MIDI Yoke 1. At first sight it seems to work : when pressing a key on my keystation, my VSTi on cubase plays what has been transformed by PD. What disturbs me is that whithin a few minutes, PD and Cubase crash so I have to restart my computer. You'll understand that it could become really painfull to make a track if both applications crash. I took "a lot" of precautions eg. desactivated audio on PD so that only cubase grabs the audio ports (ASIO) I'm working on Win XP and when crashes occur, it seems that the Minidump folder is the cause of the problem. Does anyone had such a (bad) experience on XP ? Is there any solution ? Thanks for your support touti ------------------------------------------ Faites un voeu et puis Voila ! www.voila.fr

compiling CVS maxlib in Linux with Pd > 37
by David NG McCallum 12 Nov '04

12 Nov '04

Olaf, Apologies to all if this has already been dealt with... I found that in order to get Maxlib (from a fairly recent CVS download) to compile in Linux with Pd .38testXX I had to delete lines 27 and 29 in the files netclient.c, netrec.c, and netserver.c. I assume that maybe the "PD_MINOR_VERSION==37" should actually be a ">=". I have no idea though, I don't actually know what I'm doing. I just guessed that deleting those lines would fix something... :-/ Cheers, David -- __ _ _ _ _ __ ___ _ ___ __ _ _ _ ____ __ Music wants to be free http://sintheta.org

any2ascii Windows
by Ian Smith-Heisters 12 Nov '04

12 Nov '04

Hi all, I've found what looks to be a very useful external called any2ascii by Marc LavallÃ©e on the Pd site. Has anyone successfully compiled this for Windows? Are there any alternatives that work under Windows for converting a number stream (coming from [comport]) to ascii? Thanks, Ian
