[LAU] [ANN] Qtractor 0.6.2 - The Boson Walk Beta is out!

by Rui Nuno Capela

So it's summer, they say. White bright and light pastel colors sparkling on every corner and turn. Cheesy and silly season, they say. Alas, southerners don't apply. Sorry about that. Of course I mean the hemisphere, obviously. For whom it might concern, all anxiety has come to an end. Indeed. It all relates back to this last May 3, when a not-so-formal meeting (aka. workshop) took place while during LAC2014@ZKM-Karlsruhe, where some pertinent and undeniable requests were dodged and framed to a "soonish" implementation. And guess what? Yup, the "soonish" are no more, or so I think. Qtractor 0.6.2 (boson walk beta) is out! Perhaps an additional word is due though, about the riddling code-names that are branding the post-TYOQA beta releases. They have no personal nor logical sense, I assure you. Perfectly arbitrary now. Everything in life and the universe is way more unconventional than just a name. Without further assay. Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Release highlights: * Plugins activation MIDI controller / automation (NEW) * LV2 UI Idle and Show (>= Qt5) interface support (NEW) * Discrete editing of automation curve node velues (NEW) * Missing audio/MIDI files and plugins warning message (NEW) * MIDI note drawing on tempo-map changes (FIX) * Automation curves re-adjusted to tempo-map changes (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: http://sourceforge.net/projects/qtractor/files - source tarball: http://download.sourceforge.net/qtractor/qtractor-0.6.2.tar.gz - source package (openSUSE 13.1): http://download.sourceforge.net/qtractor/qtractor-0.6.2-12.rncbc.suse131.sr… - binary packages (openSUSE 13.1): http://download.sourceforge.net/qtractor/qtractor-0.6.2-12.rncbc.suse131.i5… http://download.sourceforge.net/qtractor/qtractor-0.6.2-12.rncbc.suse131.x8… - quick start guide & user manual (severely outdated, see wiki): http://download.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf - wiki (help wanted!): http://sourceforge.net/p/qtractor/wiki/ Weblog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: - Prevent linear and spline automation curve modes for all integer valued subjects. Also, make sure those values are rounded to the nearest integer away from zero. - Fixed save of LV2 Presets for plugins with state files. - A man page has beed added (making up Gürkan Sengün's work on debian, thanks). - When moving plugins by eg. drag-and-dropping across tracks, automation curves were being left behind, maybe leading to unpredictable mistaken behavior. Hopefully, not anymore. - Translations install directory change. - Automation curves are now automatically re-adjusted to tempo map node changes (after a ticket by Holger Marzen, thanks). - Audio/MIDI files or plugins found missing on session load are now subject for an explicit modal warning message and prompt for an immediate session backup salvage. - Changing instrument plugin programs is now an undo/redo-able command operation, especially for DSSI but also for plugins that come with the LV2 Programs interface extension support (http://kxstudio.sourceforge.net/ns/lv2ext/programs). - Drawing, selecting and/or resizing of MIDI note events that extend across tempo/time-signature changes is now made a bit more correctly over the MIDI clip editor (aka. piano-roll), especially regarding to current snap-to-beat setting (after an outstanding ticket by yubatake, thanks). - Once again, audio frame/MIDI time drift correction has been slightly refactored to improve MIDI input monitor and timing. - Discrete automation curve node values may now be edited via a numerical entry floating spin-box on double-click (as yet another request by AutoStatic aka. Jeremy Jongepier, thanks). - Pressing shift/ctrl keyboard modifiers while double-clicking on a plugin list entry now briefly reverses the current View/Options.../Plugins/Editor/Open plugin's editor (GUI) by default option preference. - Fixed an old crash lurker when switching output buses that implied a change on the number of audio channels, while on tracks that have (auto-)monitor turned on and at least one active plugin in chain (yet another ticket by AutoStatic aka. Jeremy Jongepier, thanks). - MIDI Controller assignment (aka MIDI learn) and/or automation of plugins (de)activation state has been added (as requested by AutoStatic aka. Jeremy Jongepier, thanks). - LV2 UI Idle and Show interfaces support added. - Allow the build system to include an user specified LDFLAGS (patch by Alessio Treglia aka. quadrispro, thanks).

[LAU] Video card joy

by Joe Hartley

Because who else would even care besides you lot? After going for years with anemic video cards because the "good" ones would sound like a jet taking off, I splurged and got an Asus GeForce GE640 silent. No fans, just fins and heat pipes, and a GPU that isn't close to EOL already. Now, great performance on my two monitors and sweet, sweet silence. And having replaced video cards in Windows machines and having the OS freak the frak out about a system change, a renewed appreciation for Linux. I'd pre-installed the nouveau packages from Arch, and once the new card was in place, two simple config file changes and a mkinitcpio later I was rocking it. -- ====================================================================== Joe Hartley - UNIX/network Consultant - jh(a)brainiac.com Without deviation from the norm, "progress" is not possible. - FZappa

[LAU] Control surfaces - whats already available

by Len Ovens

Aside from the Mackie and look/work alikes (with motor faders), It seems there are already some of the ideas I had, out there and being used. http://lividinstruments.com/hardware_baseii.php uses touch faders in some interesting ways. First, they are sunken faders as I had thought would give the best feel as it would keep the finger on the fader. Second, it includes an LED bar for visual feed back (something I might not have added). The third thing is probably what makes it the most interesting, though it is not fully unique to a touch fader. This is the options for how it is used. It can be used the same as any rotary encoder, showing width, offset from center, or level. It is interesting to note that a motor fader with a LED strip could do these things too, I have seen a row of motor faders that in one mode default to center for graphic eq control. An encoder is incemental in any case, and the touch fader can be set up to be as well, that is, it could be set up to work the same as the belted encoder. The motor fader could be set as incremental... so that it centres when the finger is lifted without changing the value it gives, but I think that is probably outside the best use of a fader where the knob give position feedback. The touch fader _can_ also work in the traditional fader way where the finger position matches the level. This can work in two ways: a semi-inteligent setting where the actual level would not change if the finger was not right at the current level position until the finger moved and then it would change the level more incrementally (what the mind would expect). The other way would be to jump to where the finger is. (the video show this) So it could go from full scale to no scale with one touch. (One hopes this sends a slope from one level to the next and that the rate is setable) This particular unit is not designed as a DAW controller. It could be used that way, but in my opinion it is over priced and awkward for that to be it's main use. However, the faders and how they are used are interesting. Personally, I would want my faders to have no buttons etc. below them, but for the use this controller is made for (drum pads etc.) it probably makes sense. The cost for a membrane fader is about 75% compared to a motor pot and still requires a LED strip if position indication is required. SO there is no cost saving over a motor pot that I can see. The user has to want something the membrane fader offers that can't be done with a motor fader. - incremental use. - less damage prone when thrown in a bag etc. - Maybe last longer? (maybe not too) For DAW control use, motor faders seem to be the better deal. I do want to try the rotary encoder though. either with a large wheel (actually 2-3inch is not that big) or belt with no LED strip. The on screen fader position should be good enough. -- Len Ovens www.ovenwerks.net

[LAU] another control surface question

by Len Ovens

I am wondering how those who like tactile feel in a fader would feel about a sideways rotary control. I am thinking of something like the pitch or mod. wheel on a synth. But no middle detent. Rotary encoders are great for control surfaces, but the feel of a fader as compared to a rotary knob makes faders easier to think with. I am thinking if I can use the same idea with a fader feel where the control is endless, it would work well. The box would have to be thicker of course and may be less use for stage. The box could be made thinner by making it touch sensitive and self centering like the pitch wheel, but I think that starts to make the motorfader look better. The up side of the sideway encoder is that the midi messages are just direction/number of ticks. My first thought was a touch strip like the old guitar style stage keyboards, have it inside a slot so it is easy to feel without seeing it. Moving the finger up just sends up tics and moving it down gives down ticks, so the finger can start anywhere on the strip which will be where the (virtual) fader is now and move from there. I would have to use a adc and take ticks off the LSB after doing a greater or less than calc. The encoder has this out directly. Also, ticks and direction happen to work well with the control board I have on hand... the software can change that to a hard value if required though. -- Len Ovens www.ovenwerks.net

[LAU] Writing jingles

by Louigi Verona

I recently started writing jingles, because I need them for my podcast and videos that our skeptic group produces. I did not want to use somebody else's when I have the ability to write my own. I found jingles to be a very complex and interesting material to work on. So far I've written only one jingle that I am completely happy with and I am presenting it to you here. It is a jingle that we use for our videos, when the title of the video is shown and then the video proceeds to the lecturer. www.louigiverona.ru/files/TV_jingle_1.flac Has anyone else had this experience? -- Louigi Verona http://www.louigiverona.ru/

[LAU] New GxRectifier.lv2

by hermann meyer

This tube amp emulation is inspired by the Orange AD200, but didn't intend to simulate this one. However, the simulation use 2 x ECC83, 1 x ECC81 and 4 x 6550 tube emulations, were the Orange usually use 1 x ECC83. This simulation use one more ECC83 to avoid phase inversion. Cabinet simulate a 4 x 10 and in front of all sitting a rectifier. In opposite to the original AD200, which use a 3 band tonestack, this one use again a 2 band baxandall tone control. Again, I'm interested if this suite the need of the Bass players here. get it here : http://sourceforge.net/projects/guitarix/files/lv2/

[LAU] howto get pcmcia firewire card working

by Atte

Hi I got a new laptop without firewire. So I bought a delock pcmcia firewire card to be able to use my firewire soundcard. Since I couldn't see any hardware specs for the cards I looked at before buying, I simply went for the cheapest... I've been working with firewire a lot in the past, but only with build in controllers, so I'm not sure if I should do something special to get this card going. I obviously tried plugging it in and starting jack with the firewire driver for all available interfaces, but I get these errors: firewire ERR: FFADO: Error creating virtual device Cannot attach audio driver JackServer::Open failed with -1 no message buffer overruns Failed to open server 10:35:53.707 JACK was stopped with exit status=255. 10:35:54.785 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info. Cannot connect to server socket err = No such file or directory Cannot connect to server request channel jack server is not running or cannot be started Those look familiar, they are exactly the same as on my desktop pc (that works with wirewire) when I don't have the soundcard plugged in. Of course it might be that the pcmcia card is simply not working under linux (I have no other os running, so I have to assume the card is in fact working under, say, windows). But what actions could I take to either get it working or convince myself that it's simply not supported? NB: I run crunchbang linux (=debian wheezy), which were installed prior to getting the card. The laptop is a Lenovo x220. NB2: I couldn't see anything in dmesg after inserting the card and lspci is the same with the card attached and detached... Any pointers appreciated! -- Atte http://atte.dk http://modlys.dk

[LAU] Alesis Control Pad and Hydrogen

by jonetsu＠teksavvy.com

Hello, An Alesis Control PAd is connected to Hydrogen. Channel 10.b It works although quite often when hitting a same pad, the Hydrogen instrument would not sound but instead some kind of a click is heard. Makes this with any Hydrogen instrument. When I connect an Axion 25 to Hydrogen and use the rubber pads, the Hydrogen sounds are always heard, no matter how fast a hit is repeated. Has anyone seen that kind of behaviour before and is there something to do ? I tried varying the Control Pad sensivity/velocity curve/threshold but still, the Hydrogen instument is oftentimes replaced by a click. Thanks !
