I checked and I'm actually using 0.5.19 if that makes any difference. Is there a tar ball of the more recent versions that will compile that I can test and see if the problem is fixed? The 0.5.31 version from CVS produced errors when I tried to build it. > > JackEQ seg faults no matter what I do. I was using version 0.3.7.

I'm up for doing a GDB session. However, as I've never personally had need for using GDB before, you would probably have to walk me through it. -Reuben

[linux-audio-user] Help with basic midi configuration

by Eduardo Guerrero

Hi, I'm on my first attempt at midi on Linux. I'm using MusE 0.6.0pre5 in Mandrake 9.1. I think I can start jack in a root console, but I guess for a simple test it isn't necessary, so I start muse and I get the GUI. I managed to record some notes but if I press play on the transport I don't hear anything. I'm using a sblive platinum and, for setting levels I'm using Alsa-Mixer GUI and for connections I'm using Alsa Patch Bay. I have been tweaking everything and haven't got any sound. It surely works since I can use XMMS and also I can load and hear midi tracks on KMidi. In my MusE Midi Port Table I have port 1, generic midi, going to the device EMU10K1 MPU-401 (UART) and the state shows as OK. Trying with different settings I have seen a message about DEVICE PLAYING or similar but can't remember what I did. On MusE the black activity meter is moving and mute cell has a green LED (?) on, I don't know if its on why I see such activity. But anyway I don't get any sound with it turned on or off. Any help would be appreciated, Eduardo

I'm away from home right now and my machine is offline so I will have to check later to make sure. I tried to compile 0.5.31 but I couldn't get it to build. Jamin will register itself to jack and then immediately die from a segmentation fault. Oddly enough, if I specify the input and output ports, it will fail to connect to the ports but at least it won't seg fault. JackEQ seg faults no matter what I do. I was using version 0.3.7. For what it's worth, I'm using: swh-plugins 0.4.3 Jack 0.90.1 (posix shm) Also, kind of unrelated, I just realized today that the newer versions of Jack no longer give me monitors. -Reuben

Hi all... on /., there is this story: Linux PCs Drive 74-Channel Pipe Organ at http://slashdot.org/articles/03/12/03/2320226.shtml?tid=141&tid=186&tid=188 The original articl is there: http://www.eetimes.com/sys/news/OEG20031203S0032 And there is this quote, making me feel warm and fuzzy :) "So the team set out to develop tone-generation software running on a stock PC. Windows was quickly rejected as unreliable, and development was done on the Linux operating system. " Well... not ready? GuyCLO~

RE: [linux-audio-user] what is DC? [was Re: Analyzing ogg files]

Heh. I didn't read the email carefully.

[linux-audio-user] Jack-0.91.1 release

by Taybin Rutkin

Jack 0.91.1 has been released. Changes: New iec61883 driver. Very experimental; this is just to get it out there. 61883 is the standard for audio+midi over firewire. Run configure with --enable-iec61883 to compile it. It requires libraw1394. Added callback for notifying clients when entering freewheeling mode and leaving it: int jack_set_freewheel_callback (jack_client_t *client, JackFreewheelCallback freewheel_callback, void *arg); Bugs fixed. Compiler warnings removed. Taybin Rutkin

[linux-audio-user] jackEQ -0.3.8

by Patrick Shirkey

Announcing release jackEQ-0.3.8 now available from sf.net and cvs commit too. http://jackeq.sf.net Added io-menu.c for internally assigning jack ports. Uses the latest swh-plugins 0.4.3. We now check the latency for the djeq plugin (although we don't do anything with it). TODO: multiple interfaces - Long interface - Tall interface (current) extra button functionality - mostly for ease of use unlimited channel support (mostly a gui design issue) variety of xfader gain slopes for better mixing.
