That problem was fixed in CVS. I don't know when another tarball will be put out, but if you download the CVS version it is fixed.

[linux-audio-user] MIDI getting killed by Jack?

by Mark Knecht

Hi, Is anyone else experiencing this problem? I set up a bunch of aconnect commands to route my keyboard controller (64:0) to a number of synths on different MIDI interfaces, and also to route the output of Pro Tools (on another computer) to pretty much the same places: aconnect 64:0 64:32 aconnect 64:0 80:1 aconnect 80:0 64:0 aconnect 80:0 64:32 aconnect 80:0 80:1 I also route Pro Tools output back to my keyboard (line 3) in case I want to plug another hardware synth in there, but nothing is hooked up to that right now. At this point I set up my mixer and play. Everything works and is perfectly fine for long periods of time. I then start Jack and within a minute or two I lose MIDI connectivity. I can run alsaplayer or other audio apps and I still get audio, but there is no more MIDI connectivity. I look at the synths and they are not receiving MIDI input. (No event lights.) I then stop Jack and I immediately hear a bunch of MIDI notes get played.These notes were stored from when I wasn't getting connectivity. At this point I have MIDI back for live playing until the next time I start Jack when it happens again. I do this 4 or 5 times and at this point I cannot get MIDI back at all. I have to completely power down as far as I can tell. I tried rebooting and had no luck the one time I did that. I don't know what to look at to figure out what could be causing this. Hardware and modules shown below. Thanks, Mark 64:X - HDSP 9652 80:X - MidiSport 2x2 Wizard root # lspci 00:00.0 Host bridge: VIA Technologies, Inc.

[linux-audio-user] Latency question

by millward

How bad is 2 ms latency? I'm trying to decide upon a sound card and I've noticed that the Creative Sound Blaster Audigy 2 has a 2 ms latency, but offers "hiss free" audio fidelity at 106 dB SNR. The Delta 410 has zero latency, but its $200 US. Now I'm an idiot at this high end sound card stuff, so I'm not sure what really matters. All I want to do is use Linux Audacity to record my own multi-track creations and convert LP 33rpm records to CD. I'm sick of tape hiss! After 4 tracks my analog tape machine is useless. So I bought this here computer to get away from that hiss and maybe record something I can listen to without grinding my teeth. Any adice would be most welcome!

Re: [linux-audio-user] Generating drones, take 2

by Pedro Lopez-Cabanillas

You can generate a note-on event from bash, with something like this: echo -n $'\x90\x45\x70' > /dev/midi01 The above command plays the A note on "/dev/midi01" x90 is the MIDI note-on status byte x45 = decimal 69 = A (440 Hz). x70 is the note velocity If you want to stop the sound, use: echo -n $'\x80\x45\x70' > /dev/midi01 where x80 is the note-off status byte. > For reference I want to be able to generate drone tones on my MIDI.

Alsa is supposed to have a good midi api, so > how so I insert a midi event into my souncards midi output interface!! > FT You need to discover which /dev/midiXX is your soundcard wavetable synth. If you prefer to use ALSA rawmidi devices, replace /dev/midiXX with /dev/snd/midiCxDy, where "x" is the card number and "y" is a device number belonging to this card.

[linux-audio-user] pd+jack

by Steve Harris

When running Frank's exmaple pd patch (and all the others I've tried) under JACK, using the Planet CCRMA version of pd I get lots of IO Errors reported by pd, even though there doesnt seem to be any dropouts, the cpu load is low and jack doesnt report any xruns. Is there a .pdrc file or something where I can set the block size to make it match jacks? Or is there something else wrong? Cheers, Steve

[linux-audio-user] pd patch needed for demo

by Steve Harris

Can anyone recommend a simple pd patch that wont take too much CPU, runs happiily in jack and takes a pair of streams does something noticable and outputs a pair of streams? The examples I tried generally dont do straight processing. I should be able to make one myself really, but I dont have pd-fu :( Thanks, Steve

[linux-audio-user] Jack problem in Brazil

by Alexander

Hi! I'm brazilian and I don't speak english. So... please... be patience :) I have install jack 0.80 in one notebook Compaq presario 1200 with sound-card snd-via-82xxx(this module is from Alsa-Project). All songs in my coputer play with no problems. But when I try start jackd the system showme this error: JACK compiled with System V SHM support loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|nomon|swmeter|rt jackd: pcm.c:689: snd_pcm_nonblock: Assertion 'pcm' failed. received signal 6 during shutdown (ignored) I create all of directories of README. And I put in fstab the lines: none /mnt/ramfs tmpfs defaults 0 0 shmfs /dev/shm shm defaults 0 0 My kernel support shm and i can mount manually this directories. I do this because before my last installation(compile) I use --enable-posix-shm But in this time I remove all jack files os my system and killall -9 all process of jackd and recompile with stadard options. The error is the same(but change the first line "with POSIX ..." for "with System V..."). Is OK. So... my jack is compile with NO errors and the module of my sound card is ok. The process of arts, esd, nas, etc, NOT exist in my process list(I use WindowMaker). I have the directories(mounted) /mnt/ramfs and /dev/shm. I don't have any sound aplications started(no one). But I get the same error. I create the /tmp/jack with permissions 777. When i start jackd this directory is removed!!!! What's this error? Somebody have some idea what is this? I speak to Patrick Shirkey and I get much help, but my problem seems to be in my system. Any help? Thanks a lot! Alexander Brazil - Rio de Janeiro

[linux-audio-user] Recording from Line-In

by G Cote

I'm having problems recording from line in. Without knowing exactly what's going wrong, all I can say is that I can only playback "silence." As I'm recording, I can hear the audio being fed back through the external speakers. I can also use various mixers to mute/unmute and set the volume on the "Line" setting. So I'm pretty sure everything is hooked up right. I initially tried using sox/notlame/mpg123 ... # record and encode $ sox -t ossdsp -w -r 44100 /dev/dsp -t cdr - | notlame -k -v -S - /tmp/out.mp3 # playback $ mpg123 /tmp/out.mp3 I've since tried to simplify things ... $ rec -d /dev/dsp /tmp/out.wav $ play /tmp/out.wav Neither of them work. System details are provided below. What else can I do to troubleshoot this? Thank in advance - gary System . redhat 8.0 (2.4.20-19.7) . alsa-0.9.6 .
