Re: [PD] Experiencing a higher CPU load with 0.47-0 and 0.47-1.

Do you want to share your patch? I could test it on my machine with 0.46 and 0.47 -----Ursprüngliche Nachricht----- Gesendet: Sonntag, 26 Juni 2016 um 13:27:23 Uhr Von: "Dario Sanfilippo" <sanfilippo.dario(a)gmail.com> An: pd-list <pd-list(a)iem.at> Betreff: [PD] Experiencing a higher CPU load with 0.47-0 and 0.47-1. Hi, list. I'm loading the same patch with 0.46-7, 0.47-0 and 0.47-1 - all 64bit. The last two have a significantly higher CPU load. I'm on OSX 10.11.5. Has any of you experienced anything similar? I haven't changed my [vd~] objects into [delread4~], are they calling the same piece of code? The patch is almost exclusively using signal objects, have some of these been modified in 0.47-0 and 0.47-1? Thanks for your help.

freeverb~ known Bug
by José Rafael Subía Valdez 02 Aug '16

02 Aug '16

I am testing the latest "deken" version of freeverb~ to see if an old issue regarding dividing by 0 was fixed. years ago, freeverb~ would just continue to overload until the audio dropped, this was due to the fact that it processed 0 signal and created conflict (I found this out in an email thread years ago -can't find it now). the simple solution was to have freeverb~ always process a noise~ signal in extremely low amplitude. the latest version in deken does not reach the point of overloading the CPU, but whenever it has 0 signal to process it still spikes the CPU usage. I wanted to ask who was in charge of this object to see if there is interest in getting this fixed. ps. it is very easy to reproduce, just use the example in the help file and watch the CPU usage while it has some signal to process and when it doesn't. a small video to show the issue: https://www.dropbox.com/s/e4g2ty142wx7h48/freeverb-desktop.m4v?dl=0 -- José Rafael Subía Valdez www.jrsv.net

current status of [midiout]
by Christof Ressi 31 Jul '16

31 Jul '16

Hi, what's the current status of the [midiout] object? there have been warnings in the past and the help patch doesn't say much about it. for example i found this old thread in the list archives: https://lists.puredata.info/pipermail/pd-list/2010-02/076074.html here Martin says: >> Shouldn't [midiout] be renamed to [sysexout]? It only does sysex, you can't send any other kind of MIDI message with [midiout]. I'm on Win7 and [midiout] works like a charm. I can send both channel and system messages (though I have only tried system common and system realtime so far, still have to test sysex). I can easily play MIDI files with [mrpeach/midifile] -> [drip] -> [midiout] on my old Roland D110 :-). my question is: have all those supposed issues with [midiout] been fixed? does it work the same way on all systems? are there any pitfalls I have to consider beforehand? @Miller: would you mind adding a note to the helpfile that [midiout] only accepts single characters as floats but no lists? it took me some time to figure that out... or even better: adding a list method? ;-) Christof

Re: [PD] freeverb~ known Bug

Hi José, Attached patch demonstrates there is indeed a spike about 18 seconds after the inlets went silent. On my machine the spike is ~15%, while normal operation is at ~4% ([;dsp on( and [set bypass 0(. (Xubuntu 14.04, i3 CPU, 2.93GHz). I will look into it, but no success guaranteed. I am not a freeverb~ expert). Greetings, Fred Jan -------- Forwarded Message -------- Subject: Re: [PD] freeverb~ known Bug Date: Fri, 29 Jul 2016 11:38:47 +0100 From: José Rafael Subía Valdez <jsubiavaldez(a)gmail.com> To: Fred Jan Kraan <fjkraan(a)xs4all.nl> no test patch requiered, open the example and see for your self. turn freeverb~ on, and then stop sending signal to it. after about 10 seconds (in my machine) cpu starts to climb up (this with cpu monitor that pd brings "load meter" under media menu). It escalates until 50% (in my machine). if you then send signal back into freeverb~ the cpu goes down. and so on if you repeat.

vline~ in a patch with dsp off
by i go bananas 28 Jul '16

28 Jul '16

Have noticed that vline~ still takes message inputs when the dsp in the patch is switched off. I can't really think of any situations where that is useful. The problem is, that new messages get added to the message list, making it longer and longer as more messages are input. Miller, would it be possible to disable message input when vline~ is in a patch or subpatch where dsp is off? At the moment, it needs to be done manually with spigots, etc.

unable to type certain characters
by Christof Ressi 26 Jul '16

26 Jul '16

Hi list, which characters are 'forbidden' in Pd message boxes? E.g. I'm unable to type a backslash or curly braces. I get the following error message: 'keycode #N dropped' (where #N is the ASCII code). I tried both on German and English keyboard layout. I'm on Win 7. I noticed that in the help file for [text fromlist] you can see a backslash in the message box (apparantly used to escape the semicolons), so I guess it should be possible... Also, could someone have a look at the attached patch and check if they get the same errors as me? Christof

list devices without starting PD
by oliver 26 Jul '16

26 Jul '16

hi, dear list ! i tried to use the -listdev option of pd.exe to get a list of available audio and midi devices, and to write the output into a textfile for later "grep" usage. here's what i wrote on the command line (w32): pd.exe -batch -listdev > D:\Temp\devices.txt the problem i encountered is, that PD always gets started, and the output of "-listdev" is written into PD's console window but not into the textfile i declared. "D:\Temp\devices.txt" exists, but is empty, and an instance of PD was started. do you know a way to just get this specific information without actually starting PD ? P.S.: i know about the "mediasettings" external, but i really would like to do this on the command line, WITHOUT actually starting PD. thanks oliver

Read/write textfiles in ASCII/HEX?
by Christof Ressi 25 Jul '16

25 Jul '16

Hi list, does anyone know of an object for reading/writing a textfile as a stream of ASCII or HEX characters? I want to be able to open arbitrary files and process them, like in a hex editor. Christof
