[PD] Fresh XP install, extended works but not vanilla?
Hi all, I've come across a problem that has me stumped. I've recently bought another laptop which is the same model/spec as my current one. I've installed Win XP SP2 (again, same as other laptop) fresh from the OEM disc, and tried to run PD vanilla and it wouldn't open. Nothing happened when double clicking the EXE. I downloaded the latest vanilla version (I think I had been running an older version) from Miller's page and the latest extended. Again vanilla wouldn't run. Extended installed fine though and that works. I thought tha installing extended might 'fix' vanilla but that still won't run. I opened the command line and ran the pd.com and it said there was an TCL error? But no windows pop up and nothing else happens. I don't have much info to go on... pd.com spawnl: Invalid argument C:\pd\bin\wish85.exe: couldn't load TCL Does anybody know how I should attack this? Or can anyone help? Thanks in advance as always, John. ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] Fresh XP install, extended works but not vanilla?
Thanks guys. I've decided to abandon this idea and just clone my current XP harddisk as it will be going into an identical machine. I liked the idea of a fresh install – who knows what amount of registry gremlins I've picked up over the years – but my current disk works, it's fast and the audio performance is good not to mention all my software configurations, tweaks etc. don't have to be re-done. Thanks for the ideas. I already tried putting the /pd folder right at root C: still didn't run. Also it didn't run before I installed extended so the registry idea doesn't help either. If it aint broke etc. On Wednesday, 3 September 2014, 15:20, Py Fave wrote: > > >some ideas > >first check if your pd path contains spaces. > >where on your disk is pd ? > >then check if pd-extended installer put some keys in registry, >wich would mess with vanilla. > > > > >2014-09-03 3:31 GMT+02:00 Max : >> -BEGIN PGP SIGNED MESSAGE- >> Hash: SHA1 >> >> I guess it might be hard to find someone with a "fresh" XP install >> since it is EOL. >> >> >> On 09/03/2014 03:27 AM, JF via Pd-list wrote: >>> Nobody? >>> >>> >>> On Wednesday, 20 August 2014, 19:46, JF >>> wrote: >>> >>> >>> >>> Hi all, >>> >>> I've come across a problem that has me stumped. >>> >>> I've recently bought another laptop which is the same model/spec >>> as my current one.

Re: [PD] Enable autopatch by default Pd-extended 0.43.4
Thanks Iohannes, I forgot that extended was 'behind' and that autopatch is relatively new. I'm back patching on vanilla now, and having extended installed alongside is handy to go exploring externals and documentation.

[PD] Parse/split symbol by delimiters like - or _ ?
Is it possible to split a formatted symbol such as...drums_1.wav ...to extract the float '1' and use that to assign a meaningful attribute? For example a float could represent a loop playback switch. if I have 'drums_0.wav' I would like to extract the float, find that itis '0' and then I would know that this WAV file is say, not to be looped.Or if I had 'drums_1.wav' I would be able to parse the filename, find the '1'which I now know to loop the WAV file.

Thanks Iohannes & Tim, I would be interested in how to achieve this with [text]?

[PD] Pd changelog error re list/text to/fromsymbol (was: Parse/split symbol by delimiters)
Thanks Jack, [list tosymbol] looks perfect. There seems to be an error in the release log in the Pd documentation html and elsewhere... 0.46-0 "New [text tosymbol] and [text fromsymbol] to allow string manipulation."

[PD] 0.46-5 Not allocating midioutdev correctly? Strange behaviour
I can't seem to set midioutdev correctly on 0.46-5 Win 32. When I choose a device, close preferences then re-open preferences the device selected seems to now be the next device in the list. This happens when using multiple device outs too. Then saving the preferences to the registry seems to make the device change again, (but not an device increment of one, maybe 4 or 5).

Anyone? I've tried 0.46-5, 0.46-4 & 0.46-3. All seem to save midioutdev incorrectly as already described. I presume this may be a bug in the 0.46 introduced 'saving devices by name' feature?

Re: [PD] 0.46-5 Not allocating midioutdev correctly? Strange behaviour
Thanks Miller. There is an improvement with this test version! Now I can... Open MIDI Settings. Select an output device. Close MIDI Settings. Open MIDI Settings. ...and we have the correct output device still selected (previously it incremented one). But when I... Save all settings to registry. Close Pd. Open Pd. Open MIDI Settings. ...now the device has incremented to the next device (but this is better than previous! Previously it jumped a few devices up the list) So I think there may be something still buggy but the first portion of the strange behaviour seems to be fixed. Thanks again! John.

Re: [PD] Parse/split symbol by delimiters like - or _ ?
Made an abstraction that will split a symbol by a delimiter using the new [list tosymbol] [list fromsymbol] methods (attached). (So this is for the newer vanilla versions ~0.46) Uses [List_buffer] abstraction which is a cold-inlet growable list w/ bang to output and clear. This I created to suit the purpose I couldn't find anything similar in the list-abs.

[PD] Fast convolution of 2 tables using FFT
Hi all, I decided to implement my own patch that does frequency domain convolution of two tables. Have a look at the FFTTry02Long03.pd file and you will need the attached abstractions and iem_tab [tab_complex_mul] (in the path for vanilla or just imported with pd-extended). It's very fast compared to iem_tab's [tab_conv] but the output doesn't exactly match, there is some error. It's small and I'm thinking it's because of the blocksize being very large to fft~ the tables all in one go. The ifft~ needs a very large division (blocksize) to normalise the gains so I'm presuming there's some number precision funniness going on here? If anyone could chime in on this? Any feedback/improvement ideas would be greatly appreciated. Thanks in advance, John.
