I've had a Delta 66 PCI audio card for over a decade, and it's always sounded great. I recently had to transfer it to a new PC with a fresh install of Fedora 17. Now, when I play anything using any pulseaudio client, I get a strange digital noise (sort of like static, but almost like aliasing too). This does NOT happen when running jack, as far as I can tell. Aside from disabling or uninstalling pulseaudio, is there anything else I can do? Does anyone else have this problem?

[ANN] Qtractor 0.5.11 - The Lima Oscar release!

by Rui Nuno Capela

As falling leaves drift by the window, and without any further ado: Qtractor 0.5.11 (lima oscar) is now released! Soon we'll hear a new winter's song. This code-naming series, which started on a sunny summer day two years ago as TYOQA, is now converging to an end. It will be no surprise for some that today's release precedes the very last one on that series. So let's get those autumn leaves falling and grab them while they're crispy red and gold ;) Release highlights: * Extended automation curve editing (NEW) * Extended clip selection (NEW) * LV2 UI resize feature support (NEW) * Aux-sends to audio buses (FIX) * MIDI editor overlapped event velocity/value (FIX) * Accidental export muting and/or freezing (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.11.tar.gz - source package (openSUSE 12.3): http://downloads.sourceforge.net/qtractor/qtractor-0.5.11-8.rncbc.suse123.s… - binary packages (openSUSE 12.3): http://downloads.sourceforge.net/qtractor/qtractor-0.5.11-8.rncbc.suse123.i… http://downloads.sourceforge.net/qtractor/qtractor-0.5.11-8.rncbc.suse123.x… - quick start guide & user manual (outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Adding a track now inserts it after the current one, if any; one can also drag and move a track below the last one in the track list (main view left pane). - Extended Edit/Select Mode/Automation: multi-selection mode, cut, copy, paste and delete of current track's automation curve nodes, now reached implementation ready status. - Another old silent bug bites the dust: changing track names were dropping any track gain/volume and panning automation curves when saving the session. - A primeval processing bug has been sorted out: aux-sends to audio output buses that just appear to be after the input bus where they're inserted were being left muted and silent (on a ticket follow-up by Holger Marzen, thanks). - Fixed a sure crash bug exposed when processing of aux-send plugins when inserted too early on audio input buses chain (after a ticket report by Holger Marzen, thanks). - Allow the build system to include an user specified CFLAGS (patch by Cristian Morales Vega, thanks). - Shift/Ctrl keyboard modifiers now set to extend current clip selection while in main track view's Edit/Select Mode/Range, Rectangle modes. - Main Edit/Select Mode/Automation icon retouched to look a bit more obvious and intuitive, hopefully ;) - Allow to change the velocities/values of the current selected events which have the exact same onset times and hide beyhond each other on the MIDI clip editor's pane below the main view piano-roll (ie. the one that represents MIDI event values as a bar chart). - Fixed some problematic playback/export muting and annoying cleanup freezing, due on audio tracks with too many clips eg. more than hundred clip splits (hopefully fixes an issue reported by Louigi Verona, thanks). - LV2 UI resize feature support/control added. - Fixed dedicated MIDI control and MIDI metronome port connection restore conflict (thanks to jhammen catch & patch:). - New user preference option added: reverse middle-button role to Shift/Ctrl keyboard state, in special regard to edit-head/tail vs. play-head positioning while on the main track and MIDI clip editor (aka. piano-roll) views.

Lives: some beginner questions

by rosea.grammostola

Hi, Trying out Lives video/VJ tool. I want to make video art for a live gig. Its mostly making a clip from a picture and adding some effects to it, realtime effects and normal effects too. Im not planning to add effects live, but I want to apply the live realtime effects before the show. Im working in the clip editor. I will use Lives to switch to the next clip for the next song. What is a right format, size and resolution to export to, so I can use the clips during the gig? Audio is not needed. Tips for this workflow is welcome! Thanks in advance, \r

fltk linking problem

by Will Godfrey

Over the last few weeks I've been going through Yoshimi with a fine-tooth comb bug hunting, with some success (and much frustration). I'm doing this on my 'office' computer which is running debian testing on a 64bit AMD - fairly similar to my music machine. During the week, I did an update via synaptic and now suddenly when I try to compile Yoshimi it fails to link, giving the message: Linking CXX executable yoshimi /usr/bin/ld: /usr/lib/x86_64-linux-gnu/libfltk.a(Fl_x.o): undefined reference to symbol 'dlsym@@GLIBC_2.2.5' /lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make[2]: *** [yoshimi] Error 1 make[1]: *** [CMakeFiles/yoshimi.dir/all] Error 2 make: *** [all] Error 2 will@debian:~/yoshimi_20130926/src$ The investigating I've done suggests that something has changed in cmake so that yoshimi now needs a more 'correct' identification of fltk. I sort of gathered that cmake.txt was the place to look, but doing so tells me nothing. fltk is there but none of the information really makes sense to me. Although I don't like doing anything experimental on my music machine, I can do that for the time being as it is running an earlier version of the distro but presumably the new requirement will eventually hit the stable releases. Can someone help me sort this out please. P.S. A current version of ZynAddSubFX doesn't have this problem, but the build structure is now very different so I couldn't find any points of comparison. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[ANN] Radium 1.9.31

by Kjetil Matheussen

Radium 1.9.31 is a big release with many new features and bug fixes. 1.9.31 is the first release with Pd embedded. Pd is a " Real-time graphical dataflow programming environment for audio, video, and graphical processing." (http://puredata.info/) Pd embedded in Radium has got approximately the same features as Max for Ableton Live. (https://www.ableton.com/en/live/max-for-live/) Screenshot: http://folk.uio.no/ksvalast/radiumpd.png Video 1: http://folk.uio.no/ksvalast/radium_pd.ogv Video 2: http://folk.uio.no/ksvalast/radium-pd-invertnote.ogv Radium homepage: http://users.notam02.no/~kjetism/radium/ Most important changes 1.9.30 -> 1.9.31: * New demo song: BlowFish! Made by www.magnetophon.nl * Save hashmap elements in sorted order so that songs can more easily be compared textually * Menu entry to show name of all included pd externals * Help menu options to edit keybindings and menues * Song comment dialog * Fix "Switch Window Configuration" menu option * Removed "Error. y2>=window->height: ..." error. Just print to stderr instead. * Removed the "Something strange just happened in the function Blt_markVisible" warning (print to stderr instead) * Option to set number of scrolls per second. Scrolling too often can be tiresome for the eyes. * Make it easier to connect objects and see connections in the mixer, plus adjust object sizes * Patchbay sound object * Fix crash loading Soundfonts in the Fluidsynth and Sampler instrument * Show stars around filename if theres unsaved data * When quitting or loading, only ask sure/yes/no if edited since last save. * Change "Set Patch For Track" to "Set Instrument For Track" in the instruments menu. The word "patch" should not be exposed to the user anymore. * Be able to load files with DOS char set * Changed internal radium block size to 64 (similar to Pd) * Sending note events between sound objects (green lines) * Enable undo for on/off effect controllers * Pd extended is included as a sound object. 921 externals are included. GUI is working. Several instances is working. Can be used to write both audio effects and note effects. * Fix qt paths on Archlinux (Javafant/archlinux) * Many minor bug fixes

midi in python, 2 pygame.midi questions

by Atte

Hi I'm working on some midi thing in python. I had a hard time finding a decent library. In the past I used PySeq alot, but that's tricky to install and seems un-maintained. So I settled for pygame, and it's going ok. However: 1) In PySeq I created inports and outports that were visible for instance in qjackctl. Is that possible in pygame (currently I just connect to the right client from python)? Why would I prefer one over way over the other? 2) If I unplug the connected client or press ctrl-c (my preferred way of exiting my programs) I get: PortMidi call failed... PortMidi: `Bad pointer' type ENTER... How can I exit a pygame program cleanly without getting errors? 3) One of the things I'd like to do I automatically connect to any client that shows up while the program is running and *gracefully handle it* if clients disappear while the program is running. I imagine the first is a matter of scanning for clients every now and then, but right now I get the error mentioned in 2) if I pull the plug on a device that my program is connected to. Any ideas how to handle this? Any feedback is greatly appreciated! -- Atte http://atte.dk http://modlys.dk

No audio with Debian Wheezy (+ 3.10 bp kernel) on Intel Haswell processor...

by dafreedm＠gmail.com

Hi, I'm running stock Debian Wheezy (7.1) --- except for a kernel upgrade (3.10-0.bpo.2-amd64) from Debian backports --- as well as XFCE, on a couple different hardware configs. However, I'm struggling to get audio to work properly on my new Intel Haswell board. (1) On a Thinkpad x220: Audio works great, out of the box (2) On a Supermicro X10SLQ (Q87 chipset) with Haswell i4770S: Audio doesn't work at all --- no audio at all comes out of standard rear headphone jack. (NOTE: Supermicro website identifies audio capabilities as provided by onboard RealTek ALC888S chipset, but lspci [below] instead identifies Intel HDA audio, courtesy of Haswell. I worry that this might be an issue.) Could this be an issue with the kernel, or should I be looking elsewhere. I was under the belief that 3.10 (unlike the 3.2 kernel that shipped with Wheezy) had fairly comprehensive support for Haswell in general! Some more information is attached below... I don't have much experience trouble-shooting audio problems, so I appreciate any suggestions / pointers.

A music quality article of interest (OT but not much)

by Pete Wright

I go all he way back to when music came over the AM radio, clipped, attenuated, stomped, squashed, and premasticated. The "stereo" of my day wasn't stereo (yet) and we called it Hi-Fi (for high fidelity) and we built our own amps or assembled Heathkits. So now (according to Steve Guttenberg) we are back to stomped and pre-chewed, except around LAU where we all still roll our own one way or another.
