[LAU] [ANN] Qtractor 0.1.1 (futile duchess) released!

by Rui Nuno Capela

Hi LAUs, After some time in quarantine, meaning that it just passed almost 40 days since its last public appearance, the frivolous debutante has matured a bit but not that much. Truth is, it is not quite healed and in fact, it is getting seriously bloated ;) Qtractor 0.1.1 (futile duchess) has been released! Qtractor is an Audio/MIDI multi-track sequencer application, written in C++ around the Qt toolkit. Its primordial 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 Desktop Audio/MIDI Workstation GUI specially dedicated to the personal homestudio. It sits confortably tagged as for the techno-boy bedroom home-studio. There's no genre segregation here, it also applies to techno-girls ;). Now seriously, it even has its own Wikipedia entry already: http://en.wikipedia.org/wiki/Qtractor. Back to business, these are the major highlights for this release: - Draft user manual, contributed by James Laco Hines. - Native Linux VST plug-in support. - Initial DSSI plug-in support (audio effects only atm.) - User configurable keyboard shortcuts. - JACK server auto-start. - Clip fade-in/out relative resizes. - Auto time-stretch now optional. - MIDI capture/record input quantize. - Major plug-in infrastructure rewrite. - Seamless plug-in drag-and-drop. Check it out, from the official project web site: http://qtractor.sourceforge.net http://sourceforge.net/projects/qtractor Direct link for the source tarball download: http://downloads.sourceforge.net/qtractor/qtractor-0.1.1.tar.gz The new user manual draft is also made available: http://downloads.sourceforge.net/qtractor/qtractor-0.1.1-user-manual.pdf Literal change-log follows. since the last 0.1.0 (frivolous debutante) alpha release: - After some great user demand, keyboard shortcuts are finally configurable, as found provisionally under Help/Shortcuts..., for the main application menu and for the MIDI editor as well. - Debian package gets SSE optimization disabled as default. - At least some transport actions get to be non auto-repeatable when pressed for much too long, as Play and Record, avoiding the tumbling imposed from the keyboard. - For the first time ever, jackd auto-start is now allowed (!). - OSC service support through liblo gets optional at configure time, now leading the way to proper DSSI plug-in hosting. - All plug-in widget controls count are now capped to one hundred. - Plugin paths setup is now made available on the options dialog, overriding each of respective default settings, as implicit from the LADSPA_PATH, DSSI_PATH and VST_PATH environment variables (see View/Options.../Display/Plugin Paths). - Clip fade-in/out lengths are now kept relative to tempo changes and also to clip offset and length changes (clip resizes). - Automatic time-stretching for all audio clips when session tempo changes, may now be disabled/enabled as a global session option (see View/Options.../Audio/Playback/Automatic time-stretching). - Double-clicking on an empty area (de)selects all clips on track. - MIDI capture (record) quantization is now an option, possibly handy for some jerky performance musicians, as the one found in myself ;) (see View/Options.../MIDI/Capture/Quantize). - The global options dialog (View/Options...) has seen its Display tab page being moved back and to the right. - Major rewrite of the plug-in infrastructure, adding primordial support for DSSI and native VST plug-in flavors. - Drag-and-drop of plug-in instances are now allowed intra- and inter-mixer strip chains, either on tracks or buses. - Turning track record off while recording is rolling was leaving the session in a inconsistent recording status, now fixed. - A random but instant crash upon audition/pre-listening player onset was hopefully fixed. Cheers && Enjoy -- rncbc aka Rui Nuno Capela

Re: [LAU] Jackd and Other Alsa applications at the same time.

The Jack "server" cannot share the sound device with another program. Naturally, when jack is running programs using Jack can use the sound device through jack. Other programs are out of luck. > Shall i set my KDE sound alerts to "no sounds " mode ? If you wish. If you don't set this flag, you might find yourself unable to start jack at points when KDE has decided to use alert sounds and has "taken over" the sound device.

If you are not, you will definitely get problems like the ones you are describing. Sampo

[LAU] What became of tapeutape

by Julien Claassen

Hello! Does anyone know, what became of tapeutape? Was/is there anything after 0.0.5? There were great plans, but unfortunately I didn't find anything new, after early-mid last year. That's a pity!

[LAU] mixer app for traverso

by Atte André Jensen

Hi I'm normally using ardour for recording audio and routing/applying effect to various soft synths. Now I'm trying out traverso (just for the fun of it) but need somewhere to connect all my synths and applying ladspa on them. One of the things that is nice about using ardour is that it's relatively straight forward and safe to let ardour handle all connections, something that seems to be missing from jack-rack. Any ideas? For instance, what do you "midi-only" people do about your softsynts in terms of mixing, applying ladspa and recording the final result? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk

[LAU] Multiface panning

by Brett McCoy

I have another question about the Multiface II -- it's all setup, works perfectly without any configuration on my part, using PlanetCCRMA on Fedora 7, but the L/R panning seems a bit strange (the same machine dual boots to Windows, and the issue is there also). Everything is at default settings, when I pan things hard left, everything is panned hard left as expected. When I pan hard right, I don't get hard right audio, everything seems to be 'in the middle' (mono) but still playing through both monitors. I have the Multiface outputs 1 & 2 going into my S/W which goes to each monitor (M-Audio monitors). I see this issue regardless of what application I am using, and using the TotalMix tool also, I can't seem to get anything to pan hard right.

I'm struggling with a similar problem. Based on what I've read it's possible to change IRQ settings in the BIOS with some computers. My laptop doesn't let me do this :-( but you could look in your BIOS and see if it's possible. -Katie

[LAU] Pardus user Pops and clicks problem

by Arda Eden

Hi there, I'm new to Linux Audio Users mailing list. I'm a Pardus (a Turkish distro) user and i'm trying to get rid of Cubase Protools etc. For a long time i downloaded and setup most of the audio packages and i'm using them for a while. My audio Card is an M-Audio 24/96 and it works fine. There's no latency etc. But i hear too much Pops and clicks when using soft synths. Especially when doing something else like dragging windows or other things. This problem is same for Ardour. Any action i do,(like dragging something, moving mouse) affects the sound processing. Too much Pops and clicks. I set my buffer to 512 samples and my hardware is strong enough. Any ideas ? Or previous threads about this ? -- Arda EDEN Cumhuriyet University Faculty of Fine Arts Department of Music Technology

[LAU] debian->ubuntu, alsa config, buildin laptop speakers

by Atte André Jensen

Hi I recently switched from debian to ubuntu on my ibm T41. Under debian the build in speakers would not sound when in the docking station but under ubuntu they do. This is rather annoying, since the docking stations sound output is connected to my speakers. Anyone have any idea what/where I should/google/edit/install to get my beloved debian behavior under ubuntu? -- peace, love & harmony Atte http://atte.dk | http://myspace.com/attejensen http://anagrammer.dk | http://modlys.dk
