MIDI programmed music box

by Henning Thielemann

At the Linux Audio Conference 2014 in Karlsruhe [1] there was an excursion to the museum of mechanical music instruments in Bruchsal. [2] In the museum they sold music boxes as a souvenir that can be programmed by punch tapes. [3] I wrote a simple Haskell program that converts a MIDI file to the punch tape. [4] As an example I arranged a song of a colleague for the music box. [5,6,7] Unfortunately, the music box is restricted to whole tones (i.e. no "black keys") and it cannot play the same note again in a short time interval. My prefered solution would be to print the graphics on an empty punch tape, but I could not obtain an empty one. They are only sold with a printed grid. Furthermore the original punch tapes are not made of paper but of plastic. I do not know whether you can print on it using a plain laser or ink jet. I might try thick paper instead but I suspect that it will wear out quickly. However I already know that my laser printer cannot handle the length of the original stripes. Thus I printed the graphics with original width but shrunken length to regular paper and transfered the dots from there to the punch tape manually.

LazyLimiter released.

by Bart Brouns

Hi everybody, I'm announcing the first release of my lookahead limiter: LazyLimiter v0.3.01 https://magnetophon.github.io/LazyLimiter/ This is my attempt of a clean yet fast brick-wall limiter. Thanks to Sampo Savolainen for providing the initial inspiration. Very special thanks to Yann Orlarey, who spent an evening at LAC2015 with me, to optimize the algorithm and make this thing actually usable. I'm looking forward to your feedback! Cheers, Bart.

Qtractor 0.6.7 - The Lepton Acid beta release!

by Rui Nuno Capela

It's alive! Qtractor 0.6.7 (lepton acid beta) is out! Release highlights: * MIDI instrument rendering on audio export (NEW) * MIDI clip editor view/event criteria persistence (NEW) * MIDI clip editor resilience on record/overdub (FIX) * Generic plugin form position persistence (NEW) * JACK Transport/Timebase master option (NEW) and yet more tiny lurking critters swatted ;) Well, the major highlight to this release is in fact this brand new and way long overdue feature, seamlessly integrated to the faithful and regular audio track export function: MIDI track instrument plug-in rendering and mix-down (aka. freeze) is now real, as long their audio output goes onto selected buses, aka. stems, mix-groups, whatever a mix/mastering head would name it! nb. on the (very esquisite) Qtractor arch-model parlance, those are just called "audio output buses" and that ain't gonna change, any time soon, so stop it! A word of caution must be told by now: dedicated (JACK) audio output ports are off-the-grid, so sorry. Maybe this silently makes a notch towards the DAW epitome, though Qtractor still claims to be just a plain and honest sequencer--with yet another DAW-like feature addition--the same as it ever was. Nuff said. Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Change-log: - MIDI clip editor (aka. piano-roll) position, size, and view/event type criteria are now persistent, across session and user preferences application state. - Generic plugin form widget position is now also preserved across open/save session cycles. - MIDI clip editor resilience is about to get an improvement, fe. it doesn't close on stopping record/overdub anymore. - Introducing (JACK) Timebase master setting as an option to Transport mode (cf. View/Options.../General/Transport/Timebase). - LV2 plug-in MIDI/Event support now slanted for deprecation. - Spanish (es) translation added, by avid Reyes Pucheta. - It's live: audio track export (cf. Track/Export Tracks/Audio...) has been deeply refactored to finally include MIDI track/instrument plugins rendering (aka. freeze) on selected audio output buses on mix-down. (EXPERIMENTAL) - MIDI file player now does (N)RPN 14-bit controller events. - Track properties dialog output bus switch fix/optimization; also fixed multiple DSSI instance reference count on close. - Fixed for some strict tests for Qt4 vs. Qt5 configure builds. - German (de) translation update (by Guido Scholz, thanks).

[ANN] Vee One Suite 0.6.3 - A sixth beta release

by Rui Nuno Capela

[UPDATE] As a micro dot release override, the current sixth beta release is out and crunching the earlier fifth to oblivion ;) Howdy, The 'Vee One Suite' of 'old-school' software instruments, aka. the 'gang of three' have bumped over another tiny notch: synthv1 [1], as one polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as one drum-kit sampler, are now being released to the masses. Again ;) There's no big audible changes, if any at all, yet this fifth beta release is rather a probable bug fix drumkv1 LV2 on Ardour. Anyway, it's all gone as follows: - Sample file drag-and-drop support has been added to the note element list widget (drumkv1 [3] only). - Main widget layout changed as much to allow sampler display and element list to expand or grow vertically as needed (samplv1 [2] and drumkv1 [3]). - Sample file path mapping has been fixed for LV2 plugin state restoration, which were preventing Ardour to reload any of the saved session or preset sample files in particular (drumkv1 [3] only). - Custom knob/dial behavior mode options are now introduced: linear and angular (aka. radial) as far to avoid abrupt changes on first mouse click (still the default behavior). - Fixed for some strict tests for Qt4 vs. Qt5 configure builds. We're still available in dual form, as business as usual: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. Enough to tell, the Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later. As always, have (lots of) fun :) **synthv1 - an old-school polyphonic synthesizer [1]** synthv1 0.6.3 (sixth official beta) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Stoat 1.1 Released

by Mark D. McCurry

The 1.1 version release of stoat is now available. Stoat is a STatic (LLVM) Object Analysis Tool which is used to perform static analysis on C/C++ projects involving realtime constraints. The analysis traces feasible callgraphs within a program and detects cases where it may be possible to invoke a non-realtime function such as malloc from a realtime context. Hopefully this will help developers find possible bugs which other tools or manual code review might miss. New from the 1.0 release - Basic Dump Output - Support For Try{}Catch{} - Support For Rtosc Callbacks - Wildcard Support For Function Specs - stoat-compile/stoat-compile++ utility - Parallel Analysis - Namespace Support - Translation Unit Local Template Alias Support - Multiple Inheritance Vtable Support To get the source or to report any issues, just see the github page: https://github.com/fundamental/stoat Enjoy, --Mark McCurry

LV2 1.0.0 Released

by David Robillard

The first unified LV2 release, LV2 1.0.0, is out. This release merges the previous lv2core package with all the official extension packages, as well as example plugins, lv2specgen, and additional data. From a developer point of view, the biggest change is that all LV2 API headers can be used by simply checking for the single pkg-config package "lv2" (for compatibility the previous "lv2core" package is still installed). Implementations are encouraged to abandon the "copy paste headers" practice and depend on this package instead. With this release, several new extensions have become stable that together greatly increase the power of LV2: atom, log, parameters, patch, port-groups, port-props, resize-port, state, time, worker. Download: http://lv2plug.in/spec/lv2-1.0.0.tar.bz2 Documentation and more detailed change logs: http://lv2plug.in/ns/ More information about LV2: http://lv2plug.in/ Enjoy, -dr
