[linux-audio-user] ALSA 1.0.9-rc1 warning!

by Lee Revell

ALSA 1.0.9-rc1 has a bug that is fatal for SBLive! users. Your system will hang as soon as you play a sound. The Audigy is unaffected. emu10k1 users, please wait for -rc2, or make sure to apply the fix I posted to alsa-devel yesterday. Lee

[linux-audio-user] Mellotron flute looped (thanks to Paolo Ingraito)

by Emiliano Grilli

Forwarding Paolo's email (I didn't see it in the archives...) ----- Forwarded message from Paolo Ingraito <Paolo_Ingraito(a)onde.net> ----- Hi to all, I' m Paolo, that italian user who made the looped version of the reed of the mellotron sound (www.viandanze.com/materiale/mello.sf2) I found the mello sf2 by John Check and I extracted the single sounds in order to make a looped version of the samples... The only one completely finished of the three sounds is the Flute. Here you can download the patch... www.viandanze.com/materiale/melloflute.sf2 It was very useful for me having the samples already sliced and saved with the right note name (b3flute, c4reed and so...). Let me know what do you think... I used a mix of crossfading loop and traditional looping linking the end and the start of the sample with zero-points (I made crossfade looping with SoundForge an audio-editor, then I exported the wav to kontakt). Only one thing, I used a program to convert the patches from the kontakt format, so I can' t know how I can group the all mellotron patches in one sf2 file (well I hope someone knows how to do this!). Paolo Ps. Well, I' m a WinXP user, but I' m very interested in this kind of free-music projects..! ----- End forwarded message ----- -- Emiliano Grilli Linux user #209089 http://www.emillo.net

[linux-audio-user] Playing MIDI

by Til Schubbe

Hallo, I want to play a MIDI-file with a "normal", internal soundcard. The sound-howto seems to be outdated (7/2001). The midi-howto tells something in "8.2 MIDI file players" so I installed pmidi but I get the following: til@debian:~ - pmidi -l Port Client name Port name til@debian:~ - Then I installed yiff which is now running on 14541/tcp and fluidsynth and got 2 soundfonts: fluidsynth -ni Fender2.sf2 /tmp/export.mid fluidsynth: warning: Failed to pin the sample data to RAM; swapping is possible. fluidsynth: error: The "default" audio device is used by another application Failed to create the audio driver I can play .wav with wavp. Here is some module-info: til@debian:~ - lsmod |egrep snd snd_seq_oss 33408 0 snd_seq_midi 7712 0 snd_rawmidi 21408 1 snd_seq_midi snd_seq_midi_event 6272 2 snd_seq_oss,snd_seq_midi snd_seq 55184 5 snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_seq_device 7308 4 snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd_intel8x0 29376 0 snd_ac97_codec 76536 1 snd_intel8x0 snd_pcm_oss 56992 0 snd_mixer_oss 19328 1 snd_pcm_oss snd_pcm 92808 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_timer 23044 2 snd_seq,snd_pcm snd 55044 12 snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq_midi_event,snd_seq,snd_seq_device,snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 7648 1 snd snd_page_alloc 8324 2 snd_intel8x0,snd_pcm I'm running Debian Sid on i386.

[linux-audio-user] Audigy problems

by Esa Linna

Hello, Two problems with Audigy 2 ZS soundcard. 1. I see no inputs in mixer software 2. When recording multitrack with Audacity, the sound from the first track is also recorded to the second track. I choose "Play other tracks while recording new one" from Preferences. Also the audio from other software (like XMMS) is recorded to Audacity, if I play from other software and record with Audacity at the same time. Distro: Mandrake 10.1 , kernel 2.6.8.1-12mdk. I also have integrated soundcard on my PC (VIA 82C686A/B rev50). Thanks in advance, Esa Linna

I use Beatrix. I'm not a hammond player but I found the sound quite expressive and, to my ears, real. Beatrix is currently OSS but I patched it to work with Jack (crudely). Try it with OSS, then let me know if you want the patch. -Mercury

Sorry. :-\ > also, why are you using gnome-alsamixer? theres a great app "Emixer" made especially for the echo cards. its in alsa-utilities or maybe alsa-tools... What???

Shayne, I believe that Net jamming is just over the horizon. For full duplex audio, it seems, latency is the big issue. Data takes time to move. The dynamics of how that works seem to vary with Net technology, but there will always be some latency. Since you brought up Skype-- Matthias Grob (inventor of Echoplex Digital Pro) and I recently had a conversation over SkyPe. At one point, we tried some percussion with household objects.. but I found his Brazilian beats + latency hard to follow!! Your suggestion to use this latency as a feature is interesting to me. This is a major direction I want to go with FreeWheeling- the live looper I'm working on. Basically, FreeWheeling lets you capture and play with multiple loops in real-time. What I want to do with FreeWheeling is to have users able to connect to a common jam room. As different users capture loops from their improvisations, the loops become available to other users in real-time. Since the loops are syncronized to a common downbeat and tempo, Wolfgang in Germany can take Latifah in Brooklyn's loops and add them to his own improvisation. There are a lot of possibilities with both live collaboration and storing loops to form larger pieces of music that persist over the Net. It is a type of collaborative improvisation I am going for. To make this happen I need to find some volunteers- people who want to try jamming together through loops. I have been working on other features in FreeWheeling because I'm not certain that I have the user base to pull this off yet. But with a few genuinely interested people, we could make this a reality. I'm most interested in the power that music has to cross borders and touch people. In this world seemingly fragmented, I think it is important for us to hear each other's stories. If I can play music with someone from another culture, that to me is much more interesting than producing an album or going after a certain style. I see music as a social process, a healing tool-- and I think we have an amazing opportunity to use grass-roots technology to create communities of music. Thanks, Shayne, for giving me the nudge I needed to write this-- it's been brewing in me and this thread over net jamming has been my catalyst. Blessings, Mercury
