[LAU] ZynAddSubFX chagneing tempo in an instruments effect ?

by Svend-Erik Kjær Madsen

Hi I have found one of the factory instruments useful for a new project. It's the Resonance Synth from the Synth group, but the echo tails comes a little to fast, they are about tempo 120 and I would like them to be 100 or even lower, how can I change that ? I've been fidget round with the instrument editor without any luck so far, and I do not understand how it works at all, I just want to play :( Help is much appreciated. Thanks in advantage /Sv-e

[LAU] [ANN] Qtractor 0.2.0 (frolic demoiselle) is out!

by Rui Nuno Capela

Qtractor 0.2.0 (frolic demoiselle) is out! ------------------------------------------ Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework [1]. Target platform is Linux, where the a Jack Audio Connection Kit (JACK) for audio [2] and the Advanced Linux Sound Architecture (ALSA) for MIDI [3] are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Qtractor is free open-source software, distributed under the GNU General Public License (GPL) [15]. Author: Rui Nuno Capela <rncbc at rncbc dot org> Weblog: http://wwww.rncbc.org Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Download: http://downloads.sourceforge.net/qtractor/qtractor-0.2.0.tar.gz Executive summary: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework [1] (no Qt3 nor KDE dependency). - Uses JACK [2] for audio and ALSA [3] sequencer for MIDI as infrastructure. - Traditional multi-track tape recorder control paradigm. - Audio file formats support: OGG (via libvorbis [6]), MP3 (via libmad [7], playback only), WAV, FLAC, AIFF and many, many more (via linsndfile [4]). - Standard MIDI files support (format 0 and 1). - Non-destructive, non-linear editing. - Unlimited number of tracks per session/project. - Unlimited number of overlapping clips per track. - XML encoded session/project description files (SDI). - Point-and-click, multi-select, drag-and-drop interaction (drag, move, drop, cut, copy, paste, delete, split) - Unlimited undo/redo. - Built-in mixer and monitor controls. - Buil-in connection patchbay control and persistence (a-la QjackCtl [13]). - LADSPA [5], DSSI [11] and native VSTi [12] plug-in support. - Unlimited number of plug-ins per track or bus. - Plug-in presets, programs and chunk/configurations support. - Audio/MIDI clip fade-in/out (linear, quadratic, cubic). - Audio clip time-stretching (WSOLA-like or via librubberband [9]), pitch-shifting (vib librubberband [9]) and samplerate conversion (via libsamplerate [8]). - Audio/MIDI track export (mix-down, merge). - Audio/MIDI metronome bar/beat clicks. - MIDI clip editor (piano roll). - MIDI instrument definitions (a-la Cakewalk(tm) [15]) - JACK transport sync master. - MMC control surface enabled. - Configurable keyboard shortcuts. Requirements: Mandatory: libqt4 [1], libjack [2], libasound [3], libsndfile [4], LADSPA [5]. Optional: libvorbis [6], libmad [7], libsamplerate [8], librubberband [9], liblo [10], DSSI [11], VST-SDK [12]. Disclaimer: Qtractor is still in some alpha stage of development, although already functional it surely has a plenty of lurking bugs. It also lacks some features that some might find critical in the application field. All is not lost, as the following are among the ones planned to be worked on in the times to come (not in any particular order): - Automation and MIDI controller mapping. - Session/project templates. - Puch-in/out and loop recording (takes). - Audio clip cross-fading. - Audio effect send/return aux. inserts. - Clip locking, muting, normalize (gain). - LV2 plug-in support. - JACK MIDI support. - Tempo and key signature map. - Paste-repeat command. - MIDI SysEx manager. - MIDI event list editor. - MIDI editor (piano roll) draw mode. - MIDI groove/swing quantize. - OSC interface. - Scripting. - Etc. etc. Change-log: 2009-07-18 0.2.0 The Frolic Demoiselle - MIDI clip filename revision logic is now introduced, thus avoiding the proliferation of several numbered SMF's on each edit/save; some lurking bugs were exposed in the MIDI clip externalization method but promptly squashed. - Fixed a mouse release event glitch while in drag-and-drop items in the Files tree list widget. - A dummy plugin type option has been devised, just to bear with some troubled behavior of the lovely JUCETICE plugins (View/Options.../Plugins/Experimental/Dummy VST plugin scan). Bad news are that all, yes all as in every native VST plugins, are indistinguishable from being just pure audio effects, either mono or stereo, whatever, and thus all being considered full-blown stereo VSTi instruments (which are the vast mainstream and rather interesting majority, nevertheless:). - The plugin selection dialog (Add Plugin...) now features the option whether the selected plugins should be activated on insert. - Mixer strip titles now have distinguishable type icons, either for audio or MIDI, and shown on all buses and track strips. - Major optimization breakthrough: muted audio tracks aren't streamed any longer, saving precious CPU cycles from decoding, resampling, pitch-shifting, time-stretching, plugin effects, whatever. - Incredible as it might be, audio/MIDI track record monitoring is now mixed (or merged) with rolling playback content, thus not as mutually exclusive between record and playback states anymore; also, track mute/solo states doesn't apply to recording material anymore. - Main form timer slot gets corrected and now independent of current process buffer-size in regard to JACK transport synchronization. - All file references in session state file are now stored as relative paths to main session directory. - DSSI/VSTi plugin presets can now be explicitly recalled from file (ie. Open/load preset) through this new tool button whether visible while in the generic plugin form. - Due to some trouble with newer Qt >= 4.4 applications regarding font size configuration, a new global user option is now available to the rescue: View/Options... /Display/Base font size (default is no-op). - Logarithmic scale is now taken into effect by control parameter sliders, in the generic plugin editor dialog as provided by LADSPA and DSSI plugin types. - MIDI track bank/program does not default to zero (PC#0) anymore. - Second attempt for Qt4.4 build support, regarding the bundled atomic primitives, now corrected and way more seriously :). - Long due DSSI/VSTi plugin host implementation has taken shape for MIDI instruments (eg. soft-synth plugins); DSSI reached its full host implementation and VSTi is already kicking as well (HIGHLY EXPERIMENTAL). - DSSI/VSTi plugin presets may now be stored to external XML files, which should include all parameter values and configuration data chunks, taken as proper state snapshot and subject for recall. - Dedicated audio output bus option is now also accessible for all MIDI instrument plugins, either set globally as a default mode in View/Options.../Plugins/Instruments or in the plugin context menu for MIDI tracks, as an undoable command. - Fixed a potential crash-exception due to freeing a null-pointer, raised on some ever stringent platforms and while adding tracks to empty sessions, which is the same to say this was crashing more than always:). - Loop turn-around is now taken care of, as this has been found missing and causing noticeable gapping when un-muting or changing MIDI track events while in playback. - An off-by-one bug was fixed while inside MIDI cursor backward seek method, which was missing all other events that have the same exact onset timing. - Attempt to load Qt's own translation support and get rid of the ever warning startup message, unless built in debug mode. (transaction by Guido Scholz, while on qsynth-devel, thanks). - Only one application instance is now allowed to be up and running, with immediate but graceful termination upon startup iif an already running instance is detected, which will see its main widget shown up automatically (Qt/X11 platform only). - Clip fades have now a slight transparency. - Avoid loop read-ahead on initial audio clip loading. - Messages file logging makes its first long overdue appearance, with user configurable settings in View/Options.../Logging; options dialog was slightly rearranged and moved the Plugins section into a new tab page. - Audio/MIDI drifting correction was missing its own correct and due (re)initialization whenever playback is (re)started; also, MIDI metering synchronization has been fixed once again. - Fixed session cursor backward seeking, specially applicable when playback passes the end of overlapped clips. - Fixed potential crash when opening bogus audio files. - Time-stretch FIFO buffer implementation is now made generic, as template, fixing a destructor memory leak in the process. - Include legacy headers, stdlib.h and string.h, where necessary to build with stricter gcc/g++ >= 4.3.

[LAU] a 100% guaranteed firewire interface for linux?

by ::surian::

Hi folks, I need to buy a mobile áudio interface to give some linux áudio workshops here in Brazil. I saw some options listed "suported" in the ffado database, but also lots of forums with people saying they can't use that devices in their machines. So, I'm very afraid of buying something that won't work, and this interfaces here in Brazil are very very expensive... : ( Could you suggest me some interfaces that are guaranteed to work for me? I was especially thinking about the edirol fa-66. my laptop is a hp pavillion dv6700 with ubuntu 8.04 thanks a lot you all! surian

[LAU] Crackling in ZynAddSubFX

by Peter Lutz

I'm very new to Linux audio recording, so I apologize in advance if I'm missing something obvious. I have a brand new computer with an M-Audio Delta 44 audio card running the latest version of Ubuntu Studio 8.04. I've been experimenting with software synthesizers using a USB MIDI keyboard, and I've managed to get QSynth working very well and have had some success recording that. I thought I'd try ZynAddSubFX since it sounds amazing. The problem I'm having is that the sound crackles (that's the best word I can think of to describe it) when I play it. The very odd thing I've discovered though is that if I record ZynAddSubFX in Ardour, I don't hear any crackling during playback of the recording. It's only as I'm listening to ZynAdd in real-time as I play it. I've tried using different speakers and headphones, but it makes no difference. I suppose I could just record it and try to ignore the crackling as I play, but it would obviously be ideal to have no crackling at all. I've tried tweaking both the ZynAdd settings and JACK settings (although my guess is that JACK settings are fine, since I haven't had any issues with recording live instruments or recording QSynth) but to no avail. I have the sample rate in ZynAdd matching the one in JACK (48000Hz) and have tried different buffer sizes in ZynAdd but haven't noticed a difference. I've also noticed that it usually doesn't crackle when I'm using the default instrument in ZynAdd, only once I switch to a different one -- then it seems pretty continuous no matter which instrument I switch to after that. Does anyone have any ideas as to what could be causing this?

[LAU] bassguitar

by schoappied

Hi, I'm searching for an (second hand) cheap bassguitar. Do you have suggestions for me? Which brands are 'good' in a low price class? Where should I be alert for when buying one? What about a amplifier? Do I need one, or can I play it using Linux? Thanks in advance, /D

[LAU] OpenMoko FreeRunner and Real Time Kernel

by Ken Restivo

I just received my OpenMoko FreeRunner phone and have been poking around in it, trying to learn my way around it. I found this interesting: root@om-gta02:~# cat /proc/version Linux version 2.6.24 (build@barbie) (gcc version 4.1.2) #1 PREEMPT Thu Apr 24 08:23:36 CST 2008 Hmm... the FreeRunner ships with an Ingo patched RT kernel? It's tempting to try to port JACK and maybe FluidSynth to it and see what happens. -ken

[LAU] [ARDOUR] Way of sorting tracks in Mixer and Tracks Views

by Aurelien

Hello, I'm currently working on a huge project[1] with about 150 tracks at the end (recorded by bunches of 24). [1] for me, at least! I've created a model with those 150 tracks, but the fact is that some instruments (10-15 max) don't play on some tunes, and I prefer to delete the related tracks so that it is more readable. Please note that there are 24 Tracks "active" and a bit more "viewable", and the same 24 tracks are viewable in Mixer View, on which there also is busses (6). As I delete a track (in the Tracks View), the sorting of the tracks totally change in both of the view, and I can't figure out how it changes. I didin't find any logics behind this, even if I suppose it is the case. Worse: when I sort the tracks manually in order in the tracks view, it doesn't put them in the same order on the mixer, as the busses are viewable from the mixer but not from the Track View. And I finally cannot get an ordered sort in one and the other. Could someone give me a trick about it? I use ardour 2.4.1 on a Debian Lenny/64 Studio (ardour comes from 64studio).
