Clip detection
by Chuckk Hubbard 24 May '06

24 May '06

This might be a beginner question- is there an object to allow clip detection? I want to do some batch recording from a tape deck, and I'd like to set it and go and come back and check whether it clipped... Thanks.

sending pd-announce to pd-list
by IOhannes m zmoelnig 24 May '06

24 May '06

recently we had some discussion on pd-ot, which most of you probably have missed: the basic idea was to automatically send [pd-announce] mails to the pd-list. historical background ===================== up till now, there were 2 ways of using pd-announce: groupA assumes that people subscribed to pd-list are also subscribed to pd-announce, so they only send announcements to pd-announce. unfortunately this is not the truth (there are about 1350 people subscribed to pd-list (including double and disabled subscriptions) and only approx 650 subscribers to pd-announce) groupB does not assume that all pd-list-subscribees are also subscribed at pd-announce, and therefore post announcements to both lists, resulting in cross-posts for those who _are_ subscribed on both lists. currently 2/3 of the email-addresses subscribed to pd-announce are also subscribed to pd-list. (this does not include people who are subscribed to both lists with different email-addresses) my original intention for separating the lists was to make "important announcements" available to people who are not really interested in following all the discussion at pd-list. this means, that pd-announce should be a subset of pd-list (all mails going to pd-announce are also meant for pd-list). the reason why it became 2 different lists was merely technical. so what? ======== both groupA and groupB "annoy" a rather large number of people (>100), either because recipients get announcement-mails 2 times or not at all. the solution could be simple: subscribe the entire pd-list to pd-announce (so all announcements go to pd-list and thus to all pd-list subscribees) AND disable the direct delivery of pd-announce for all those addresses that are also subscribed to pd-list. does this sound good? drawbacks ========= - people subscribed to the pd-list who do NOT want to receive pd-announce mails would have to take care of that themselves. (but even this task would be simplified in relation to the cross-posting solution). - it is still a solution driven by technical feasibility rather than what we really want to acchieve. (imho, an ideal solution would make pd-lists (un)subscription a matter of (de)activating a check-box in the user-preferences of the puredata.info portal) feedback is welcome mfg.adsr. IOhannes

help on externals
by AshK 24 May '06

24 May '06

Hello, Most of the time I use pd-extended on MacOS so I never bothered compiling externals or anything else. Now I have a problem because I'm using pd on Linux ppc (debian etch on a mac) and I need some externals. I couldn't find pd-extended for linux ppc and I'm not sure to understand, pd-extended only comes as run time / compiled version? there's no way to grab the sources and find an easy way to compile it for any platform? If not then I need to compile some externals myself. I already tried and got nothing but lots of errors. I first tried to compile grid from Yves Degoyen and got stuffs like "invalid use of undefined type xxxstruct _widgetbehaviour"... I think Yves' code is pretty clean, that must be a problem on my system. So before going further I need to know if I can get pd extended to work on linux ppc or if I have to compile the externals myself, and if anybody knows some documentation about what I need to do on a fresh debian install to get the usual make, make install... to work properly. Thanks a lot and sorry if I'm a bit off topic with my compilation questions. AshK

[writesf~] "time to flush all the output to disk"
by Chuckk Hubbard 24 May '06

24 May '06

The help says that between a stop and the next open the object must have time to flush all the output to disk... I'm just wondering, is this typically a matter of milliseconds or more like a few seconds? I mean, is it necessarily just one block, or it could be longer? Thanks. -Chuckk -- "Far and away the best prize that life has to offer is the chance to work hard at work worth doing." -Theodore Roosevelt

pd-extended on Linux PPC
by AshK 24 May '06

24 May '06

Hello, sorry I'm not announcing that I succesfully compiled pd-extended on Linux PPC and that I want to share it with the world. I'm rather asking if someone already have a working version of pd-extended for Linux PPC. That would be very nice if you could share it. Thanks

[comport] crashes on Windows
by Hans-Christoph Steiner 24 May '06

24 May '06

I have incorporated the "OVERLAPPED" asynchronous mode code for Windows from Piotr Majdak in the [comport], and now it crashes pretty regularly. I just committed the comport-stress-test.pd, which makes Pd crash within a couple minutes. It seems to be caused by transferring a lot of data from Pd to the serial port. FYI: I am using an Arduino to test. I did a little test to see whether its the new code, or whether there were crashes before. So I compiled revision 1.10, which uses the standard synchronous mode for data transfer. This version seems to last a bit longer, but it crashes in a much uglier way: it zombies Pd and doesn't let go of the serial port. So its an improvement, but still, it crashes a lot. Any of you Windows hackers want to take a stab? I am going to test things on Mac OS X now. .hc ________________________________________________________________________ ____ "The arc of history bends towards justice." - Dr. Martin Luther King, Jr.

[comport] changes
by Hans-Christoph Steiner 24 May '06

24 May '06

Just an FYI: I have been working on [comport]. I added Piotr Majdak's Windows improvements and that's working well. Plus I made the port device name generation dynamic. On Windows, its just "COM" plus the device #, on UNIX platforms, its a glob pattern, so it numbers them based on which are available. Also, the [devicename ( message now directly opens the port rather than setting a port # to that device name. I hope I didn't step on anyone's toes (I checked with Wini before), but I think it'll work much better now. .hc ________________________________________________________________________ ____ News is what people want to keep hidden and everything else is publicity. - Bill Moyers

binbufs and guis for the Externals HOWTO
by Hans-Christoph Steiner 24 May '06

24 May '06

It would be very nice to add the binbuf and gui APIs to the externals howto, since these are useful and mostly undocumented AFAIK. Anyone have some existing material on these topics? .hc ________________________________________________________________________ ____ News is what people want to keep hidden and everything else is publicity. - Bill Moyers
