Just wondering if there is a better (or even worse) command line MIDI file player other than timidity? timidity seems to work okay, but it seems to be pretty much abandonware with little or no updates over the last 10 years. Not to mention it's totally confusing set of options. OTOH, it seems to be pretty solid and works for me. So, maybe I should leave things alone :) Most of the time I play my midi files though a real synth, but there are times when using software is nice. Never sounds as good to my ears ... and I have to assume the software or the sound files? -- **** Listen to my FREE CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

Axiom 25: using pads with Hydrogen only (+ qsynth on keyboard)

by jonetsu＠teksavvy.com

Hello, What would be the best way to have the pads of an Axiom 25 trigger Hydrogen only while the keyboard itself would trigger qsynth ? Qsynth has sounds on all 16 MIDI channels and it seems that it's not possible to disable reception for a specific channel channel. Nor turning the sound down for a channel. Is this at all possible ? I can see an app that would be in-between qsynth and the Axiom 25 MIDI input that would filter out MIDI input for a given channel, does that exist ? Also, in qjackctl there are two MIDI outputs for the Axiom 25. 0:USB and 1:USB or MIDI 1 and MIDI 2. Conencting 0:USB to Hydrogen and USB:1 to qsynth could maybe be the way, but then the Axiom 25 would have to be told to send pads to 0:USB and keys to 1:USB, which I'm not sure it can do. The Axiom documentation has a lot of zones and groups and such, but there's no section on how to actually achieve some results, with examples, apart from very simple connection examples. Any comments/suggestions appreciated ! Cheers.

Bitwig and Jack sync

by Aurélien Leblond

Hello all, So, Bitwig supports Jack except for the transport part. I was wondering, is there any other way to manage to sync them? Some kind of other transport (midi?) master? Thanks in advance for any ideas, Aurélien

Confusing qjackctl playback devices, no jackd output

by Roberto Suárez Soto

Hi, recently something weird happened. As usual in this cases, I'm not aware of making any changes, this happened all without my intervention. This reinforces my theory of a leprechaun infestation at home, but I'll leave that for another mailing list. The symptoms: I launch qjackctl, start jackd, and then hydrogen. When I hit "play", there is no sound. There are no errors in qjackctl's message window, and hydrogen is playing nicely (vu meters are going up and down as if nothing happened). After messing around for a while, I found that I could make hydrogen sound again changing the connections in qjackctl "Connections" window: instead of connecting the two outputs of hydrogen to "playback_1" and "playback_2" (which is the default as soon as hydrogen is started), I connected them to "playback_7" and "playback_8". I have a built-in HDA-intel sound card, and I believe that these outputs are "side-left" and "side-right". But I had never had to do this, playback_1 and playback_2 always worked. I'm using headphones, in case that's important. More interesting yet: while hydrogen worked flawlessly with playback_7 and playback_8, I tried to do the same with rosegarden and it didn't work. I haven't tested other jack-enabled tools yet, but I'll do it ASAP to see if hydrogen is the exception or the norm. Is it possible that due to some leprechaun-induced change in the system (or maybe, though not as probable, some change that I did and can't remember now) the playback devices in qjackctl have changed? How could I define them so playback_1 and playback_2 went back to their "proper" meanings? I'm aware that this is not really a well defined problem report, but I'll gladly welcome any suggestion or tip that could help with this. And with the leprechauns. Pesky little beasts. Thanks in advance, -- Roberto Suarez Soto Ave Nevis, ave ferrum, Ave tela, ave cruor, Ave pugna, ave moritur.

[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).

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
