Ideas for future features
by Larry Troxler 10 Mar '98

10 Mar '98

There are a few things, that I thought wouldn't be too difficult to implement, and thought I would post them now, to get opinions as to whether these would a) fit with the philosiophy of pd b) Have been done in the Mac version c) Break soon if I coded them, due to new versions of PD. d) Are better done other ways Here we go: 1) Could/should there be an object that transmits a bang when an abstraction is loaded. THis would be to trigger initialization, such as loading files into arrays, etc. Presumably, there would be a similar object which bangs when the file is closed. 2) How does IRCAM and/or Opcode Max do score files, if they do? I was thinking, something that would probably be easy to implement and use, and at the same time very powerful, would be simply to add something to the message syntax which delays a given number of milliseconds before executing the next line in the message script. For example: foo 1 2 3 delay 20 foo 3 2 3 delay 100 bar 0.1 ... would send appropriately timed messages to the receivers "foo" and "bar". Presumably there would be a mechanism to both read such a "score" from a file. 3) Well, there _was_ a third idea but it escapes me right now.

Re: loadbang object
by Miller Puckette 10 Mar '98

> I made a loadbang object last night...seems to be working fine. You ... But there's a loadbang already in the distribution. Only thing is, I think there's a problem putting loadbangs in abstractions which I was wanting to get around to fixing. I never bothered with closebang either, although if there's a need for it I probably should include it. Anyway, take loadbang with a grain of salt for now... As to sequencing (re Larry Troxler), I think I'm going to have to put a qlist-compatible object in Pd because the whole IRCAM FTS repertory uses it. I was just thinking about whether I could afford to put that off another week or whether it's needed right away... -Miller

Re: pd 0.22 for IRIX and NT
by Charlie Kilpatrick 09 Mar '98

09 Mar '98

Hi Miller, I've gotten pd to work on my NT box now. It turns out I just needed new sound card drivers for my soundblaster card. Didn't immediately suspect this because it's a new computer and I had a feeling the latest drivers would be what was shipped. Looks like I thought wrong. =) By the by, I discovered in the course of this that the new soundblaster drivers support full-duplex at 'CD-quality', whilst the old drivers don't necessarily.

pd 0.22 for IRIX and NT
by Miller Puckette 09 Mar '98

09 Mar '98

Hi All, I've put pd-0.22 for IRIX and NT on crca-ftp.ucsd.edu in pub/msp. Mostly I just fixed bugs. I haven't yet managed to do anything more for people's sound-card and MIDI woes on NT and W95 however, and plan this week to try to sort out the 10 or so different trouble reports I've seen on this list! The other thing I haven't done yet is get together a cross-platform release of bonk and fiddle; this should be coming soon in a separate package. The next thing I'm hoping to do is to put support in Pd for data structures and lists; this might lead to some fundamental changes, but I hope it won't give rise to incompatibilities with existing patches and externs. cheers Miller

(how) is recursion detected?
by Larry Troxler 08 Mar '98

08 Mar '98

Sorry if this is a naive question, but is implementing loops or recursive processing , by using a conditionally broken closed loop of inlet/outlet messaging (not DSP signals), allowed? Larry -- Larry Troxler -- lt(a)westnet.com -- Patterson, NY USA --

sound cards
by charlie＠joe.surf.com 07 Mar '98

07 Mar '98

Hi Everyone, This isn't a pd question, but I thought I'd poll your experience because someone here has probably had to make this decision. I am looking for a 'recording studio quality' sound card for a PC. Here are the basic specs I'm looking for: 1) Full-duplex stereo audio IO at 44.1 kHz / 16-bit. Read as: record and playback audio at the same time, both at cd-quality. The key phrase here is 'same time'. At the moment I have a Sound Blaster AWE 64 Value Card; this card seems to be capable of recording at cd-quality OR doing playback at cd-quality, but not both simultaneously. At least I haven't been successful in getting this to work. 2) Has DirectX 5 drivers. 3) Works under 95 and NT. Optional (this would be ideal): 4) Has Midi IO ports built-in Help is appreciated and apologies in advance if anyone is upset that this is off-topic, Charlie

pd-0.21 on linux...
by Charles Baker 07 Mar '98

07 Mar '98

Finally got pd-0.21 to compile on my linux platform. Mea culpa.... I had installed 'egcs' , an experimental gcc 'improvement' (even higher degrees of optimization than standard gcc available ...someone on the csound list reported a major increase in speed in csound compiled with this compiler)...the compiling went without hitch, and it reported linking ok, but died when the egcs linked binaries tried to dynamically link in libc . Which means, before any pd code even got called. So I changed back to "cc" (a link to the real gcc),and voi-la! (voi-ci?) Like my mid-western buddy always says: "like, weird, with a beard, man...." Onwards into the OSS world, and hopefully, full duplex on linux . Anybody else seen the problem I found on NT (dacs often die almost immediately, but when they don't they function perfectly.)..I betcha this has to do with the multiple soundcards I have on my system....I will try the new args to specify card/midi under NT. You know, it's nice to have the source! CharlieB

Any Linuxers having problems closing patches?
by Larry Troxler 06 Mar '98

06 Mar '98

I just merged the 0.20->0.21 changes with my personal mods, using msp's distribution. However, I now can't always close patch windows (using the File/close menu) - the window stays and I get a string of messages in the console about nonexsting objects. Does anyone else have this problem? If not, I can assume something went wrong in my merge, and I'll try from a pristine 0.21 build. A related question: are the msp and GG 0.21 tarballs now identical when compiled for Linux? I assume they would be, but if they're not, maybe that's my problem ( I got 0.21 from msp, and not from Guenter) Thanks in advance! Larry -- Larry Troxler -- lt(a)westnet.com -- Patterson, NY USA --

Re: compile...
by Charles Baker 06 Mar '98

hmmm... did you "make -f makefile.linux depend" before "make -f makefile.linux"? Miller/Gunther... is there *any*comprehensive object list? Can one be easily generated? Any new objects floating around amoung us "early adopters"? I havn't been so excited about code since....well, you can tell I have no life, huh? ;-) CharlieB

compile...
by Burton Alexandre 05 Mar '98

05 Mar '98

hello linux pd-ers... i've been building and using pd on SGI's for a few weeks now, and i just tried compiling it on my linux box. I tried to simply copy the makefile.linux to Makefile, but it craps right away complaining about "stubs.h". My linux experience and setup is quite new, and I indeed have no /usr/include/gnu/stubs.h and was wondering it was part of what package i should get... I'm based on slackware 2.0.27, upgraded to 2.0.33, running on i586/200. there is minimal info on the Linux port (which i don't mind) but i'm stuck even before starting! i guess someone here will be able to help me on this one! thanks a lot. Alex Burton. p.s. about how many pd-on-linux people out there?
