[linux-audio-user] midi won't play although sound works

by Carlyle Sutphen

I am sure I am just missing something very elementary but I have turned up all controls in kmixer and gone through all how-tos and searched in google. What I really want is to be able to compose and play with something like MusicEdit. But I don't get anywhere close. Even the simple command: pmidi -p 16:0 derdurst.mid plays silently for several minutes. Tell me I am an idiot but tell me what I am overlooking. Thank you. I am running Suse Linux 10.2. Some revelant information: carlyle:~ # cat /proc/modules | grep -i snd snd_virmidi 9600 0 - Live 0xf93dc000 snd_rtctimer 8224 0 - Live 0xf93b8000 snd_seq_oss 38400 0 - Live 0xf93e9000 snd_seq_dummy 8068 0 - Live 0xf93b5000 snd_pcm_oss 53376 0 - Live 0xf939b000 snd_mixer_oss 21248 1 snd_pcm_oss, Live 0xf9362000 snd_emu10k1_synth 12544 0 - Live 0xf933a000 snd_emux_synth 41984 1 snd_emu10k1_synth, Live 0xf937e000 snd_seq_virmidi 11392 2 snd_virmidi,snd_emux_synth, Live 0xf931a000 snd_seq_midi_emul 10624 1 snd_emux_synth, Live 0xf92fa000 snd_seq_midi 13824 0 - Live 0xf92b7000 snd_seq_midi_event 11520 3 snd_seq_oss,snd_seq_virmidi,snd_seq_midi, Live 0xf92bc000 snd_seq 60272 9 snd_seq_oss,snd_seq_dummy,snd_emux_synth,snd_seq_virmidi,snd_seq_midi_emul,snd_seq_midi,snd_seq_midi_event, Live 0xf936e000 snd_emu10k1 125728 5 snd_emu10k1_synth, Live 0xf97cc000 snd_ac97_codec 95648 1 snd_emu10k1, Live 0xf978d000 snd_ac97_bus 6400 1 snd_ac97_codec, Live 0xf953f000 snd_pcm 86916 4 snd_pcm_oss,snd_emu10k1,snd_ac97_codec, Live 0xf9756000 snd_timer 27908 4 snd_rtctimer,snd_seq,snd_emu10k1,snd_pcm, Live 0xf9733000 snd_page_alloc 14472 2 snd_emu10k1,snd_pcm, Live 0xf9724000 snd_util_mem 9472 2 snd_emux_synth,snd_emu10k1, Live 0xf96c1000 snd_hwdep 13956 2 snd_emux_synth,snd_emu10k1, Live 0xf9716000 snd_mpu401 12712 0 - Live 0xf9711000 snd_mpu401_uart 13056 1 snd_mpu401, Live 0xf96cd000 snd_rawmidi 29824 4 snd_seq_virmidi,snd_seq_midi,snd_emu10k1,snd_mpu401_uart, Live 0xf971b000 snd_seq_device 12812 8 snd_seq_oss,snd_seq_dummy,snd_emu10k1_synth,snd_emux_synth,snd_seq_midi,snd_seq,snd_emu10k1,snd_rawmidi, Live 0xf96bc000 snd 61188 29 snd_virmidi,snd_rtctimer,snd_seq_oss,snd_seq_dummy,snd_pcm_oss,snd_mixer_oss,snd_emu10k1_synth,snd_emux_synth,snd_seq_virmidi,snd_seq_midi_emul,snd_seq_midi,snd_seq,snd_emu10k1,snd_ac97_codec,snd_pcm,snd_timer,snd_util_mem,snd_hwdep,snd_mpu401,snd_mpu401_uart,snd_rawmidi,snd_seq_device, Live 0xf96f4000 soundcore 13792 1 snd, Live 0xf965f000 carlyle:~ # modinfo snd-virmidi filename: /lib/modules/2.6.18.2-34-default/kernel/sound/drivers/snd-virmidi.ko author: Takashi Iwai <tiwai(a)suse.de> description: Dummy soundcard for virtual rawmidi devices license: GPL vermagic: 2.6.18.2-34-default SMP mod_unload 586 REGPARM gcc-4.1 supported: yes depends: snd,snd-seq-virmidi srcversion: FA7EC5D028390D0CAD56ED2 parm: midi_devs:MIDI devices # (1-4) (array of int) parm: enable:Enable this soundcard.

[linux-audio-user] Firewire-Success

by Arnold Krille

Hi all, at http://www.arnoldarts.de/drupal/?q=node/557 I have written down (part of) my success-story with my new rack featuring a Presonus Firepod. It works great using the freebob-drivers by P. Palmers & Co. Thanks guys! Feel free to ask and have a nice weekend, Arnold -- visit http://www.arnoldarts.de/ --- Wenn man mit Raubkopien Bands wie Brosis oder Britney Spears wirklich verhindern könnte, würde ich mir noch heute einen Stapel Brenner und einen Sack Rohlinge kaufen.

[linux-audio-user] Muse, jack, and silence.

by St

I tried MuSE today, on my Kubuntu system. I started Jack, and MuSE, and opened up a Midi file. I saw MuSE Midi connection in the qjackctl connection window, and I was able to play the midi file through an external synth. In the Audio tab of the qjackctl connection window however, I did not see any inputs or outputs to MuSE. I imported a .wav file, but I did not get any sound by playing it. Similarly, attempting to record from my microphones, I saw that envy24ctl was getting audio from my mikes, but no connections were shown in the qjackctl connection window, and I recorded nothing but silence with MuSE. With Ardour, all of the inputs and outputs show up in qjackctl automatically. Is there something else that I must do to get MuSE to connect to jack on the audio channels? Oh, and also, how involved would it be to get my SBLive to respond to Midi events with its internal synth? Thanks, Tobiah

[linux-audio-user] hexter and debian

by Josh Lawrence

Hello list, I'm getting really, really frustrated and need some help. I've been trying for the past week to install software that depends on pkgconfig to find libraries. My most recent outing was to install dssi so I could try out hexter. I install dssi by doing apt-get install etc. Now I'm trying to compile hexter (there's no package for that), and it complains that pkgconfig doesn't know about dssi, so I need to adjust my pkg_config_path variable. Now my understanding is that, in order for pkgconfig to "know" about a library, there has to be a .pc file that contains metadata for it. Alas, there is no dssi.pc on my system. Am I stuck? -- Josh Lawrence http://www.hardbop200.com

[linux-audio-user] Qs. about audacity and script to convert wav->mp3 or ogg

by H.S.

Hello, I just started to use audacity with some live recorded music. I have a few starting questions: Audacity: 1. If the input waveform seems to go beyond the +1 and -1 scale, what does that signify? I assume that shows recording circuit is being saturated and that the output from mixer should be reduced. 2. If the input waveform is being shown saturated, how would that manifest itself in the playback? 3. On a machine, I exported a portion of the captured wav to a wav file (basically, saved a portion of the input). I then transfered it to my home computer running Debian. While that sound wave file was shown between +1 and -1 in the original machine, on my home machine is was being shown between +0.5 and -0.5 in audacity. What gives? Exporting to mp3 1. I would like to export a number of wav files to mp3 files. Instead of doing it one by one from audacity, how can I export them using a shell script? I want to be able to set some basic tag info in a file and call that file to fill in the mp3 tags automatically. In essence, I want to call a script that converts all wav files in a directory to mp3 files. And of course, I would like to be able to set the bitrate in the script. Suggestions on which tool to use for this? 2. I can export to ogg format from audacity. Can I do the same thing as (1) for this as well? Does ogg format support tags. Thanks, ->HS

[linux-audio-user] Correct CFLAGS for libDSP and libConvolve?

by Ken Restivo

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I decided I'd really like to try these convolution reverbs that people on other platforms have been using for nearly 10 years, apparently. So I grabbed jack_convolve, libconvolve, and libDSP. It seems the're not autotools-enabled, so they don't just magically figure out the right set of CFLAGS. Unfortunately, I have no idea which to use. Building libDSP, I got stuff like: gcc -march=pentium2 -mcpu=pentium4 -mmmx -O1 -ffast-math -fprefetch-loop-arrays -Wall -Werror -g -D_REENTRANT -D_THREAD_SAFE -D_ISOC9X_SOURCE -D_GNU_SOURCE -DDSP_X86 -I. -c X86.c `-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead. X86.c: In function ‘dsp_x86_sse_addf’: X86.c:479: error: unknown register name ‘xmm1’ in ‘asm’ X86.c:486: error: unknown register name ‘xmm1’ in ‘asm’ X86.c:486: error: unknown register name ‘xmm0’ in ‘asm’ X86.c: In function ‘dsp_x86_sse_add’: X86.c:501: error: unknown register name ‘xmm1’ in ‘asm’ X86.c:508: error: unknown register name ‘xmm1’ in ‘asm’ X86.c:508: error: unknown register name ‘xmm0’ in ‘asm’ X86.c: In function ‘dsp_x86_sse_mulf’: Ah, great. The CPU I'm using to build the software and (hopefully) to run it, is this one: http://www.restivo.org/projects/macmini/system-details/cpu.txt Anyone want to venture a guess as to what GCC flags to use, or, better yet, how to cheat and make autotools tell me, even though this package doesn't use it? - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFF2Tgre8HF+6xeOIcRAkjtAJwKZcDG/2O87unVVMxnmy1HiEFtsgCgmiTR S9c02T9GBq0EgoXglAlWqKc= =hf/q -----END PGP SIGNATURE-----

[linux-audio-user] ghostess

by njcross＠sbcglobal.net

I'm trying to get Ghostess' jackmidi to work in Mandriva 2007(jack 102.5). Alsa(1.0.12) is OK, but when I play through Dino jackmidi to Ghostess jackmidi I get an error and Ghostess crashes: [root@localhost src]# ghostess fluidsynth-dssi.so ghostess: ghostess starting... ghostess: instance 0 on channel 0, plugin 0 is 'fluidsynth-dssi/FluidSynth-DSSI/inst00' ghostess ready fsd-gui starting (pid 13792)... ghostess: OSC: got update request from <osc.udp://localhost:13560/dssi/fluidsynth-dssi/FluidSynth-DSSI/inst00> ghostess: symbol lookup error: ghostess: undefined symbol: jack_midi_get_event_n [root@localhost src]# I admit I'm having to try ghostess-20061127.tar.gz or Thac's ghostess-0-0.20050916.1.mdk2006.0.mde.i586.rpm to even get a Ghostess jackmidi port in Mandriva 2007. Dino and Om-synth jackmidi work OK, no problem. Ghostess is very useful and it would be great if it worked on Mandiva 2007.

It doesn't make dynamic libraries, just static ones. So the file you have build is called libjuce_debug.a .

Don't bother with that. Just let JUCEPATH in mammut's makefile point to the directory you unpacked juce into. > > hope that i get some help, really interested to get mammut working here! > If everything else fails, you can use Mammut 0.22 instead, which requires gtk1. Its not that much different.
