And I also agree, that it would be ugly, if digital pins fire without changing their state. > I cannot see any way other than using individual debyte objects for each > group unless you would come up with something completely different like > storing everything into an array and sending from there (after checking what > has changed) which would be much more complicated. Actually, I found the table based approach not that complicated and I think it is more scalable (it covers all possible 16 groups). I added a [pd polychange] subpatch that does exactly what you describe. I hopefully tested it more thoroughly this time. See attached patch. Cheers Roman

mp3amp segfault
by Nicolas Montgermont 14 Sep '11

14 Sep '11

Hello all, I am using mp3amp~ on a server and I have a segfault everytime very shortly (2-3 sec). This problem never occurred to me... pdextended is installed from the available package (without a few dependencies) my system is: stream_test$ cat /etc/motd Linux vps-1006620-2877.cp.tsukaeru.ne.jp 2.6.18-028stab069.6 #1 SMP Wed May 26 18:10:06 MSD 2010 x86_64 GNU/Linux Ubuntu 10.04.1 LTS You can find the log and backtrace of gdb down in this mail. It seems to be a libmp3lame error. The last error is always the same but i find nearly nothing about it on the web.

inactive patch consuming 100% CPU
by James Dunn 13 Sep '11

13 Sep '11

Hi list, I having some trouble with a large abstraction I've made. It's a [soundfiler]/[phasor~]/[tabread4~] based sample player that plays tracks forwards, backwards, half-speed, etc and I am also using [freeverb~] as a frozen reverb tail. It can play 5 tracks simultaneously fine, and I can manipulate them live, but when all the tracks are stopped the CPU steadily increases until it reaches 100% and I've no idea why. The tracks I'm loading are all between 3-5mins long so I'm obviously using a lot of memory. The tracks are stopped by sending [phasor~] a frequency of zero, and muting the main [*~] output. It's a bit of a sprawling mess, but I'd be really grateful if anyone would be able to look at it and tell me what's going wrong! test_patch is the patch I'm using and player2.pd is the abstraction. Also, this is on a Macbook Pro 8,1 2.7 GHz Intel Core i7 with 4GB RAM running Pd-extended 0.42-5 thanks James

Multitrack recorder
by Pierre Massat 13 Sep '11

13 Sep '11

Hi, I m trying to write a multitrack recorder based on writesf~ and readsf~ . I m faced with a serious issue... There seems to be some latency either when writing to a file or reading from it (i can't tell). This means that i can't record a second track on top of another as an overdub and playback both. Assuming that Pd's diplayed latency in the audio settings is right (???), that is 100ms, i tried triggering the readsf~ after a 100 ms-long delay, to no avail. I thought it would be a piece of cake to program this, but well, apparently it's not...? Needless to say that i can't use table as i plan to use it for possibly long recordings (my goal is to use it on a phone with PdDroidParty). So here's the question : is there any latency when writing or reading to a file, and if yes, is it measurable and foreseeable? Thanks! Pierre

xsample on ubuntu?
by J. Simon van der Walt 13 Sep '11

13 Sep '11

Any suggestions for getting xsample to work on ubuntu? I found a .rpm from CCRMA, used alien to convert it to a .deb. Looks like I have some stuff installed, but am getting these errors: /usr/lib/pd-extended/extra/xsample.pd_linux: libflext-pd.so.0.5: cannot open shared object file: No such file or directory xsample: can't load library Any ideas? tia, -- J.

Transposing samples using MIDI numbers
by Sebastian Valenzuela 13 Sep '11

13 Sep '11

Hi, Is there a way to transpose the sound of a sample [stored in a table] to match a pitch/midi note number? In my project, when a sample is played back [using tabplay~] I would like something to tune that sample to say, midi note 69 or A 440. I would like to be able to send this number to the transposing function via a number box. I am SOO close to realizing an idea, I just need this one crucial part. Thank you for your time, Sebastian

[OT] cool book (maybe relevant to list discussion)
by Andy Farnell 13 Sep '11

13 Sep '11

Anyone seen this? http://pragprog.com/book/btlang/seven-languages-in-seven-weeks I was flicking through it in Foyles bookshop yesterday and thought of many of the discussions we've had here of late. The style and content seem somewhat tuned to a web POV, but I think Pders would find something interesting. Just wondered if anyone else had read more because I'm tempted to buy it. a. -- Andy Farnell <padawan12(a)obiwannabe.co.uk>
