It's pretty simple.. I've modified the makefile (removing librt and a repetition of s_jack_audio.c) ,If not will give some errors, and I've modified the s_jack_audio.c file removing these commented lines: static int process (jack_nframes_t nframes, void *arg) { int j; float *out; float *in; /*if (nframes > JACK_OUT_MAX)*/ jack_out_max = nframes; //else jack_out_max = JACK_OUT_MAX; if (jack_filled >= nframes) { if (jack_filled != nframes) fprintf(stderr,"Partial read"); for (j = 0; j < sys_outchannels; j++) { out = jack_port_get_buffer (output_port[j], nframes); memcpy(out, jack_outbuf + (j * BUF_JACK), sizeof (float) * nframes); } for (j = 0; j < sys_inchannels; j++) { in = jack_port_get_buffer( input_port[j], nframes); memcpy(jack_inbuf + (j * BUF_JACK), in, sizeof (float) * nframes); } jack_filled -= nframes; } else { if (jack_started) sys_log_error(ERR_RESYNC); for (j = 0; j < sys_outchannels; j++) { out = jack_port_get_buffer (output_port[j], nframes); memset(out, 0, sizeof (float) * nframes); } memset(jack_outbuf,0,sizeof(jack_outbuf)); jack_filled = 0; } pthread_cond_broadcast(&jack_sem); return 0; } Johnny Petrantoni, musician, software developer. jackosx (JackPilot,JACK-insert,JAS): http://www.jackosx.com http://jackosx.sf.net --- Panda (a modular programming language): http://xpanda.sf.net > > thanks, > > chris madak > >

Re: HDSP 9632 with PD under Linux/Shortening Delays using PD...

Hi Melissa, Melissa Corso wrote: > I have successfully installed PD and used it with an audiocard (HDSP 9632) under Windows XP. However when using windows XP there is a substantial delay in the output. You will probably want to adjust your -audiobuf settings. PD has a *lot* of startup arguments [type pd --help to see them all], and one of them controls the audiobuffer size. With an RME card, you should be able to enter very small numbers. Start with 50 [ms] and see what happens. If your audio stream breaks up, you set it too low. Once you have the right number, you can save yourself the trouble of typing it again and again by making a .bat script [under windoze] or a .pdrc file [under linux] which contains all your settings. If shortening the actual DSP delay [irregardless of soundcard latency] is what you are after, then you should investigate the -blocksize argument, which sets the DSP sample blocksize. There is also an object in PD which sets the blocksize for a particular section of your patch: [block~] I think... Read the helpfile for this object for more info. > When I use linux, as soon as PD starts up I get this message and the audio card is no longer recognized (no audio output). > using non-interleaved audio input > Sample width set to 4 bytes > ALSA: set input channels to 4 > snd_pcm_hw_params_set_access (output): Invalid argument > using non-interleaved audio > alsa: set output channels to 4 > audio I/O stuck... closing audio You are correct that PD tends to perform quite well under a lean Linux system. However, PD and ALSA have had a strange divorce proceeding lately, as ALSA has taken a new direction and PD hasn't caught up with it yet ;-) Plenty of folks have said they can't run PD with ALSA at all. Probably better not to use ALSA, but get it running with Jack or with OSS-emulation for the time being. Ask around [Planet CCRMA list, ALSA List] if you need more info on this.

could the handling of local variables in message boxes be made easier?
by Eric Skogen 26 Jan '04

26 Jan '04

hi list using $0-prepended local variables and $1-prepended arguments in message boxes is really a pain. would it make any sense to allow some type of escape character to make it easier? for example, a $$1 would refer to an argument to the subwindow, but a $1 would still refer to a variable passed to the message box? or some similar code... hope this makes sense, it's early morning here :) eric

writesf~ open/start/close behaviour
by Emmanuel Rio 26 Jan '04

26 Jan '04

Dear list, I just noticed another kind of bug in writesf~ when handling 'open' 'start' and 'stop' messages manually without care : when an 'open' message is received while writing a sound file (without sending a prior 'stop'), the previous sound file is not closed before the new file is opened. With this kind of behaviour, data are of course recorded on the hard drive, but the size of the 'data' chunck (in case of a 'WAV' file) remains zero, and has to be manually changed in the binary file so that the recorded sound file can be read by another software (and PD itself). Of course, user, patches and abstractions should use the messages in the right order, but closing the current sound file before performing a new 'open' would be a very nice feature. Best regards, Emmanuel Rio OS : Windows XP PD : pd-0.37-0.msw

pdp-pidip osx +mp3 streamout~
by retu arana 26 Jan '04

26 Jan '04

hik, i fixed the problem with pidip thanks for your help and sara's tutorial... it was the freetype lib that was missing and i use the precompiled object instead off compiling it and miracle it all works and the best is that all the mp3 objects started to work also. but i still have a problem with mp3streamout~ which is all the time in the red whatever quality i set, and sometimes it plays but only short period off the sound so is this normal and the object is not working properly on osx or can i do something to make it works. (mp3streamin~is working fine) bye.

I wrote : I'm trying to use the 0.37 version just as the 0.36 I click on the pd file to launch the 0.37 that is done, and then, when I want to open for example an "audio example" in the doc folder, I get something like "no such file or directory..." can you indicate me what is wrong ? I have maybee forget how i installed the 0.36 before. thx ///////////// it's ok, it was apparently because my folder was on my desktop (windows)
