Hello. I find it a problem that instruments to Pd are distributed around the world. Starting from "www.pura-data.org" one has to spend a lot of time in getting all and in understanding what instruments are good/needed and what not. Could somebody reorganize "www.pure-data.org" so that all instruments are in a directory tree at that site? Then I could save time and download all, and put the whole directory to Pd search path. In any case, forcing one to download all files individually is a major turnout. This is a problem of many commercial sites as well (Reaktor) -- like people want buy a software and then spend month in downloading instruments one by one, three clicks per download. -*- Is there equivalent to Pluggo of Max/MSP for Pd?

[linux-audio-user] DSP2000 C-PORT and MIDI input

by Emiliano Grilli

Hello, I have recently bought the ice1712-based DSP2000 C-PORT from Hoontech and I'm really satisfied with it. I only have a little problem: MIDI! The card has 1 MIDI in and 2 MIDI out, and the 2 outs are working fine. However, I can't get anything from MIDI in :-( Anyone has that card and can confirm this problem or I have to check my hardware? Maybe ALSA get confused? With aconnect I see 2 devices (0 and 32) both as inputs and as outputs... I've tried on the staudio.com forum and they suggest to test the card under windows, but (ehm..) I don't have it... Any suggestions? TIA -- .-----------------------. | Emiliano Grilli | | emillo(a)libero.it | | Linux user #209089 | | http://www.emillo.net | '-----------------------'

[linux-audio-user] Help with Midi Express XT setup, what am I doing wrong here?

by Kent, Gary

Hi: Haven't posted to this list before, but have been using Linux audio for awhile. Any help for a linux midi newbie? I have a Motu Midi Express XT interface which I can't seem to configure correctly. I have been through all of the tutorials on the Planet CCRMA website for USB midi setup, as well as tweaked /etc/hotplug, /etc/blacklist and the /etc/modules.conf (snd_limit=4 for two devices: audio card and midi interface) with no good results. Anyone know of a place where I can find some tips on how to set this device up? I have a SoundBlaster Live card and am going to make the move to RME pretty soon. The Motu Express XT falls into the machine ok, but I can't make it sit in the machine without it stealing my audio card. I.e. I can't make both devices work at the same time. Any tips? Thanks very much for any help given, gk

[linux-audio-user] Vstserver v0.3.1

by Kjetil Svalastog Matheussen

Vstserver is a program that must be running when using programs using vstlib. Vstlib is a library that can be used by programs to run windows vst audio plugins under i386linux/i386freebsd/i386solaris/i386etc. (May require som modifications for other os-es than i386linux). A tutorial for vst plugins in linux can be found here: http://www.djcj.org/LAU/quicktoots/toots/vst-plugins/ A list of some of the plugins working and not working: http://80.61.20.184/vst/ 0.3.0 -> 0.3.1: -Added a watchdog for the processthread if its running SCHED_FIFO. If the processthread use more than 10 seconds to process a chunk, it should be killed. Tested with an endless loop, and it seems to work. -Added "make install" and "make uninstall". -Updated the INSTALL file. The installation should now be a bit easier.

[linux-audio-user] setting virmidi in modules.conf makes an jack error?

by Piotr Sawicki

Hi, I have problems with configuring virmidi and running jack. According to howto from: http://linux-sound.org/quick-toots/4-sequencers_and_softsynths/quick-toot-m… I have set /etc/modules.conf like this: above snd-ice1712 snd-pcm-oss # Configure support for OSS /dev/sequencer and # /dev/music (aka /dev/sequencer2) # (Takashi Iwai advises that it is unnecessary # to alias these services beyond the first card, i.e., card 0) alias sound-service-0-1 snd-seq-oss alias sound-service-0-8 snd-seq-oss # Configure card 1 (second card) as a virtual MIDI card alias sound-slot-1 snd-card-1 alias snd-card-1 snd-virmidi alias sound-slot-0 snd-ice1712 Then I want to run qjackctl as usual, but I get an error: could not connect to jack server as client and when I type in console: [root@pececik piotr]# jackd -d alsa -d hw:0 jackd 0.94.3 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|rt|32bit ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: No such file or directory jackd: pcm.c:687: snd_pcm_nonblock: Assertion `pcm' failed. Aborted (core dumped) [root@pececik piotr]# If I comment these lines in modules.conf and restart alsa, everything works perfectly, so what am I doing wrong?

Check with "ps aux". > sometimes i get the audio in/out stuck - closing error sometimes but > mostly the watchdog: signaling pd error just keeps appearing Do you run the latest test version from Miller's site? I would recommend doing this. Also in s_inter.c try to change this line in sys_set_priority: p3 = (higher ? p2 - 1 : p2 - 3); to be that: // p3 = (higher ? p2 - 1 : p2 - 3); p3 = (higher ? p1 + 3 : p1 + 1); instead, and in s_audio_jack.c find (around line 60) this: } else { /* PD could not keep up ! */ if (jack_started) sys_log_error(ERR_RESYNC); and throw out the sys_log_error like: } else { /* PD could not keep up ! */ // don't call log_error in jack process: // if (jack_started) sys_log_error(ERR_RESYNC); then recompile. This once did wonders here for letting Pd coexist with Jack. ciao -- Frank Barknecht _ ______footils.org__
