Re: [LAU] KDE 4.4's nice integration of Pulseaudio, ALSA, and JACK!

by James Morris

Well I thought I'd give fedora 13 (the kde 'spin') a go the other day. I've tried a few distros which used KDE, and found it quite visually appealing, more so than gnome for sure. But I'm left with the feeling I'm using Windows with it (which is better than the feeling i'm left with after using gnome ;-). Instead all I did with Fedora was install gparted and resize the gentoo partitions except I forgot to copy one of them before deleting it. Anyway, the point I'm eventually trying to get to... i decided against fedora13+kde and did a fresh gentoo install over it instead. gentoo's using kernel 2.6.34 and it seems to have the full real-time-preemption low latency desktop option.. built in, so all i've had to do was /etc/security/limits.conf wotsits - though I'm not sure if that is the real real time patch or what. james.

is there a "sourceforge" or "youtube" for MIDI ??

by Niels Mayer

Finding sites like http://www.vtmidi.org (featured on recent http://www.fromthetop.org/?ft=2&f=510026 ) and having previously found cool sites like http://www.blueman.name/Creations_XG.php or http://www.strutter.plus.com/midi/ has got me thinking.... <http://www.blueman.name/Creations_XG.php>I'm wondering if anybody has created a collaborative MIDI website. Kind of a midi wiki or midi sourceforge. With a "midi repository" using http://www.midi.org/dtds/midi_xml.php representatio of MIDI and rcs/cvs style diff repositories. The site would compile out a midi stream that you could listen to, and you could upload new versions or revisions back to the site.... Add ratings system so people can figure out what's worth listening to. It would bring a whole new meaning to the dub concept of version, no? Niels http://nielsmayer.com

like "qjackctl", but trimmed of all fat

by Aaron Krister Johnson

David, Thanks, this is excellent to know. If I can reproduce this behavior, I can intelligently code for its possible existence. So far, my next round will try to include (i.e. TODOs): 1) scrolling output for long lines 2) MIDI patching with 'aconnect' 3) fixing verbosity issues 4) help with 'h' 5) quit with 'q' as well as Control-D I'm trying to decide how best to implement MIDI patching from the main screen. By default, I could have the program be in 'audio' mode, and one could switch between modes with 'a' and 'm' for MIDI...similar to the 'tabs' in qjackctl. Ideas? More suggestions?

linuxsampler > 0.5.1 vs. pitch bend

by Fernando Lopez-Lezcano

I posted something about this a while back and never got a good answer. Time to ask again... :-) In linuxsampler > 0.5.1 I seem to be missing the pitch bend functionality. Is there anything special I have to do to get it back? A stock build of even current cvs linuxsampler does not respond at all to pitch bend. It works fine with 0.5.1. Anyone out there has this working? Can anyone reproduce the problem? -- Fernando

Announcing: ecaedl.pl Edit Decision List Capable Audio Playing

by drew Roberts

I have been looking for an EDL capable audio player for a while now but have not found one. So I hacked together ecaedl.pl which work but is very rough. More info here: http://zotzbro.blogspot.com/2010/05/edl-edit-decision-list-audio-player.html pastebin link here: http://pastebin.com/esXJwv84 Right now this needs ecaplay from ecasound and perl. mplayer is useful to create the edl files but they can be created by hand. Would any cross playform audio player group be willing to add edl playing (and creating) functionality to their player? It would make things much simpler. (I guess I really need to add in a GPL license section to the file... soonest. all the best, drew

[ANN] Qtractor 0.4.6 - The Funky Deviless is here!

by Rui Nuno Capela

So much to tell, even more to do... then one could hardly shake, this long overdue. Lousy rhymes and no miserly times. And there it is: a bug-fix release, I'll mean to ease. Oh crap! Let's get it through once and for all. With huge compliments to all who got the nerve and report as many too much idiosyncrasies (nee bugs). Don't, never look back. There's plenty more ahead, no matter where you look, or hear, whether is up or down hill :) Qtractor 0.4.6 (funky deviless) is here! Release highlights: - MIDI Editor draw mode (aka paint mode) (NEW) - MIDI Swing-quantize (NEW) - LV2 UI Instance & Data-access extension support (NEW) - JACK Session support (EXPERIMENTAL) (NEW) - LV2 Save/Restore extension support (NEW) - MIDI Editor event list in-line editing (NEW) - MIDI Clip time-stretching (FIX) - MIDI Clip editor file salvage quietness (NEW) - MIDI Control bus switching crash (FIX) - MIDI Bank-selection backout (FIX) - Initial widget geometry extents (FIX) - Input-only bus playback crash (FIX) - Bus connection persistence crash (FIX) - Drag-and-drop cloning plugins (FIX) - MIDI Editor floating-selection persistence (NEW) - Audio inserts garbage signal (FIX) A bit more or not so detailed change-log is found below.

Change-log: - Introducing a non-painting edit sub-mode on the MIDI clip editor's piano-roll (see Edit/Select Mode/Edit Draw menu). - The MIDI clip editor (aka piano-roll) is now a lot more quiet about saving its own dirty content, delegating all salvage questions to main session control. - Don't show session restart message box when changing JACK transport mode option anymore. - Dedicated MIDI control bus switching fixed. Was closing the wrong bus eventually and crashing the whole show with it (fixes bug #2989590). - MIDI bank/program backout has been corrected on MIDI track properties dialog rejection (ie. user cancellation). - MIDI bank select method has been corrected for tracks with no instrument defined (probably fixing bug #2987071). - LV2 UI Instance and Data Access extension support added; reduce LV2 external UI parameter value update flickering. - JACK session infrastructure support. (EXPERIMENTAL) - Initial widget geometry and visibility persistence logic has been slightly revised as much to avoid crash failures due to wrong main widget hidden state. - Initial mixer widget extents are now set reasonably larger. - General source tree layout and build configuration change. - Ever since smooth-ramping introduction that having at least one input-only buses were causing immediate playback crashes, now hopefully fixed. - Refactored for common engine client nomenclature, primarily provided by JACK, then secondarily passed to ALSA Sequencer, getting rid of the JackUseExactName requirement and lifting the unique/single instance restriction in the process. - Current JACK Transport, MMC Device, and MIDI Song Position pointer (SPP) control modes are now saved/loaded as part of session option properties. - MIDI clip editor's context menu crash on Qt >= 4.6 has been fixed (resolving bug #2972603). - An ancient double-free corruption has been finally fixed at the audio/MIDI bus connection persistence logic. - Improved visibility of track state buttons text (R, M, S) when turned on dark colored themes. - LV2 Save/Restore extension support kicks off. - MIDI engine read-ahead period has been shortened to half than it was since inception--now it's a 500msec cycle. - MIDI clip editor event list gets its due inline editing, for time, note, value/velocity and duration columns, just one double-click away over the target cell ;) - Add-plugin selection dialog position and extent are now remembered across invocations and application sessions (tipping by Frank Neumann). - MIDI clip time-stretching is now made available through the same gestures as audio ones, by just shift+dragging either of the clip edges. - Drag-and-copying plug-in instances (cloning) is now fixed with regard to parameter value replication. - MIDI clip editor snap-per-beat setting is now independent from main multi-track view; File/Save As... dialog fixed; the current event selection is now kept floating as long as it's possible after editing command actions; finally, edit mode has been extended to free-hand event drawing, chalking off (piano roll) draw mode from the TODO list. - Swing-quantize has finally made its overdue debut as an additional MIDI clip editor tool (see Tools/Quantize...). - Almost since its inception, audio inserts were injecting garbage random noise when not being activated, now fixed. - Dedicated audio output ports for MIDI track plugins, now have their connection persistence back in business due on session load. Cheers && Enjoy (what else?) -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

yet another yoshimi bug fix, -> 0.021

Right click instrument name change now works. For me, saving to a custom bank root seems ok, but some funkiness there wouldn't greatly surprise me. If it still doesn't satisfy, perhaps you can spell out the steps you're taking and from that I'll hopefully be able to figure out where it's going wrong. 0.021 fix right click instrument rename and a couple of bank management issues <http://www.graggrag.com/?q=yoshimi> cheers, Cal
