Makeing connections with mouse is awkward!
by Larry Troxler 11 Mar '98

11 Mar '98

Does anyone else find that it is painfully slow to patch to gether object with PD, since you have to aim the mouse in to small areas? It would be so nice if there were a way to distinguish between object-selection actions and connection-actions, other than requiring the mouse to be actually directly over a connection to determine the mode (it takes a long time to place the mouse like this!). My disadvantage once again, is that I'm in complete ignorance as to how the Opcode Max handles this problem. But, just an idea - why not do something where dragging with button 1, selects and area, and dragging with button 2 makes a connection to the nearest outlet and inlet at the beginning and end of the drag, respectiviely?

Watchdog for POSIX RT (Linux)?
by Larry Troxler 11 Mar '98

11 Mar '98

Currently, the Linux port of PD makes itself a POSIX real-time process, which means that if it goes into some infinite loop, you have to reboot your machine. Once when working with Csound, I used a software watchdogging scheme that seemed to work, and I was wondering whether it might be appropriate to use it for PD. It requires POSIX threads, but I think these have recently been folded into glibc so that everyone will have them (?) It works like this: The main program (in this case, PD), runs with POSIX real-time scheduling, but at a priority less then maximum. It spawns a watchdog thread of lesser priority (probably SCHED_OTHER), that periodically sets a flag. It also spawns a real-time task of higher priority than the main program, which periodically checks that this flag has been set, and then clears it. If it finds that an interval goes by without the flag being set by the watchdog task, it means that PD is stuck hogging the CPU, or is simply too slow for real-time, and then can terminate PD. Should we do something like this for PD? Or is there already some fail-safe measure in place? Larry -- Larry Troxler -- lt(a)westnet.com -- Patterson, NY USA --

UI duplication offset doesn't make sense
by Larry Troxler 11 Mar '98

11 Mar '98

When the duplicate function is selected, by selecting an object and using ^d, for example, the placement of the new object doesn't make sense to me; it is just a few pixels down and to the right, and on my system overlaps the original object. Wouldn't it make more sense to make the offset a large X and no Y , for example, so that there is a good chance that the new object will be usable right where it is?

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

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
