Re: [PD] Freezes with Pd-Extended and Jack
Hi all Johnny-come-lately I am . . . I've experienced this problem since 0.43 (vanilla and extended), I believe, but I haven't really investigated it, because it didn't happen that often and I wasn't able to reliably reproduce it. Now I figured out a way to reliably reproduce it. It seems the likeliness is related to jackd's latency settings. The shorter the latency, the likelier is pd going to freeze. With a setting of 128 frames/period and 2 periods/buffer, I can reliably freeze pd by turning DSP off and on. The problem seems related to the fact that switching DSP also switches the jack client on and off. I think the preferred way would be to be able to switch DSP on/off independently from switching audio back-end on/off. @Miller Are you still planning to seperate dsp switching from audio backe-end switching for 0.44?

There is 1 strange thing however : pd did some kind of buffering with midi, in order to synchronise with audio out. if you configure 100ms audio latency, then a midi loop will be between 100 and 105ms. with 10ms audio buffer out, the midi loop is between 10 and 15ms. but this buffer should not change anything on timing except adding latency. cheers c ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Freezes with Pd-Extended and Jack
I don't know. IIRC, Pd-{vanilla,extended} up to 0.42 behaved as pd-l2ork
does now. Is pd-l2ork based on 0.42? If so, they (Ivica) wouldn't have
had to fix it at all.

Re: [PD] Freezes with Pd-Extended and Jack
Two things: 1) in 0.43 there has been a rewrite of audio backend which AFAICT broke jack connectivity. 2) 0.42 branch does not know when jack has died (as in quit or crashed) and therefore hangs pd. This has been fixed in pd-l2ork. Since it is a combination of 1 and 2 there is not a patch per se that can be shared since 0.43 branch uses different code base.

J I wanted to do this, but I don't have a linux machine with firewire, so i can't test the ffado driver for the card. I wanted to try out the class compliant mode, but there is a bug in ALSA which prevents it to work. see http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28935.html I didn't wanted to get started recompiling the kernel for this. sorry. So in theory it should work, but only if you remove the bug in the ALSA part. for the record i compared the on board intel card of the linux machine, the result is quite impressive, i don't think it can get any better: /doc/7.stuff/tools/latency.pd Sampling rate 44100 Hz, delay 20 ms Blocksize 64 Ubuntu 12.04 Intel® Core™ i3 CPU 550 @ 3.20GHz × 4 Latency HDA Intel (hardware) print: 21.9012 print: 21.9037 print: 21.9063 print: 21.9088 print: 21.9114 print: 21.914 print: 21.9165 print: 21.9191 print: 21.9217 print: 21.8834 print: 21.886 print: 21.8885 print: 21.891 print: 21.8936 print: 21.8961 print: 21.8986 print: 21.9012 print: 21.9037 ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Limit bandwith for MIDI output / precise metro
Pd tries to time-stamp MIDI on input and tries to delay sending MIDI output until the correct time; but Pd's accuracy in doing this is limited by the fact that it can't input or output MIID while it is either sleeping or running (only when the scheduler polls for what-to-do-next after either a task or a sleep has finished.) It would be more accurate for Pd to rely on either software interrupts or even better on some underlying OS time-tagging mechanism (for instance by exploiting whatever portmidi does). But I have to admit I've never treated this as a high priority (which one might take as an implied value judgement about MIDI). cheers Miller On Tue, Nov 27, 2012 at 11:44:06AM +0100, Cyrille Henry wrote: Le 27/11/2012 10:36, IOhannes m zmoelnig a écrit : ... with MIDI, Pd doesn't do any buffering and no synchronisation to some external clock is done, so messages appear in bursts which you notice as a inaccurate timing.

Re: [PD] Limit bandwith for MIDI output / precise metro
I believe if you edit s_midi.c and change: if (midi_outqueue[midi_outtail].q_time = midirealtime) to if (1) and if (midi_inqueue[midi_intail].q_time = logicaltime) also to if (1) that will make it fast-as-possible.

[PD] data structures in abstractions
Hello all Is there a way to include a data structure graphical shape (filledpolygon for example) inside an abstraction's graph on parent? I saw that when trying to add a graph on parent in the data window it messes up everything.

Thanks Eldad Hi Eldad, You have to adjust the x range and y range in the canvas properties to be in agreement with the x and y size in the canvas properties. So if x size is 85, make the range 0 to 84, and do a similar process for the y. I think it's done this way for Put menu arrays where you would have a different y range depending on the situation. However, drawing instructions like [plot] give the ability to scale the values of a scalar to some screen pixel range so I don't get why this range business is part of the canvas properties (or the canvas class for that matter). -Jonathan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] data structures in abstractions
Great It works fairly well with graph on parent of the subpatch (datawindow) However, if I try to make the entire patch into an abstraction and have a graph on parent of the main window containing the graph from the subpatch it doesn't work so well. It seems to display in another patch but buggy, and it also doesn't allow me to drag and drop the polygon joints. Do you know if this should work and how?

Re: [PD] data structures in abstractions
Thanks Jonathan You are a magician. You said it works, so now it does no bugs. The only thing I can't get rid of is the datawindow name appearing in the graph on parent. No matter how many times I turn it off, once I save it and load it again, it comes back on. The name of the main graph on parent does not show, only of the subpatch I attached the abstraction here Cheers Eldad randomPolygon.pd Description: Binary data randomPolygon-help.pd Description: Binary data On 2012-11-27, at 11:11 PM, Jonathan Wilkes wrote: - Original Message - From: eldad tsabary tazberryd...@gmail.com To: pd-list@iem.at Cc: Sent: Tuesday, November 27, 2012 10:31 PM Subject: Re: [PD] data structures in abstractions G reat It works fairly well with graph on parent of the subpatch (datawindow) However, if I try to make the entire patch into an abstraction and have a graph on parent of the main window containing the graph from the subpatch it doesn't work so well.
