(no subject)

by Raphaël Mouneyres

hello, thanks to nama and ML archive, i now know about https://github.com/navicore/Jacks perl api I'm missing a callback to know the current transport position (either in seconds or BBT). Is there any way to get it from perl ? (i'm currently having trouble to make jack.osc doing the same job) thanks, Raphaël

qjackctl-0.3.11: desktop notification area support (patch)

by Zlobin Nikita

I use sometimes qjackctl to control transport during work in qtractor, because when in qtractor i open track properties to test various plugins, all other gui is unavailable, excepting only plugins gui. But this ugly popup on closing of qjackctl window is a bit annoying. My final goal was to get it with option like "Don't remind anymore", but even getting messages appeared not very easy. My implementation uses notify-send utility, which in ubuntu is packaged in libnotify-bin package. Arch wiki says, that libnotify is good for both gnome and qt4 apps, but it seems, but basic libnotify api, written on C, is glib/gobject-based, and i can't find libnotifymm (same glib, but on c++) in neither ubuntu nor portage. Though in gentoo i found even some kde stuff, using libnotify %).

LA mailing list feature request: more error (denial) feedback

by Zlobin Nikita

I just tried to send patch for qjackctl in uncompressed form, which itself is ≈430Kb, and nothing appeared in archive. I'm sure, that it is due to size limit. However, e.g., on gentoo proaudio mailing list it is usual to send patches and ebuilds uncompressed for easier review directly from mail (mailing list web ui and probably some mail clients even display them as part of message). Since it is first time, when i send some materials to this list, i did as usually. It would be better to have some error feedback - those, trying to write to list without registration at least get feedback about denial.

Drums - EDrums - Hydrogen

by Aurélien Leblond

Hi all, I have been using Hydrogen for a few years now, both by programming drum patterns or playing live with an e-drums and there are few things I'm missing... I wouldn't mind having a look into coding them, but I'd like to get the feedback/comments/opinions/screams of despair from the community. HiHat & EDrums Hydrogen only deals with close/open for the hihat control. It should be easy enough to mark the instruments as being part of a hihat and provide for each hihat instruments a range to define which one is triggered. For example close from 0 to 10, half-open from 11 to 40, open from 41 to 127. EDrum sends a cc message for how close the hihat is closed. There is already a script to do something very similar (http://www.hydrogen-music.org/hcms/node/2807) using mididings, but having it in Hydrogen would be more user friendly I guess? EDrums & Cymbal choke I believe edrums are using aftertouch for that (to confirm) - sample could simply be muted? Multi-mics drum samples Drums recording often uses several mic placements and depending how they are mixed it changes the mood of the drums. For example mixing using overhead and direct samples. I have drum samples where: - the snare is composed of under, above and overhead takes - cymbals are direct and overhead takes - kick is front, back, inside - etc... Per instrument, we could have groups of samples: - Instrument would have one fader per group and one fader for the whole instrument - Each instrument group would have its own output - Each group would have its fader - if we have multiple instruments with the group "overhead", this fader can control the gain for the overall overhead - I don't know what to do with panner - would anybody have an opinion on that? - Trigger/velocity (programmed or played live) would trigger would trigger all necessary samples What do you guys think of these proposals?

[ANN] Qtractor 0.6.0 - The Byte Bald Beta release!

by Rui Nuno Capela

Once again, it's springtime. Once again, the planet revolved and stepped forward against its mother star. Hence the three bees release... it won't be that far fetched if you find this naming a deliberate pun riddle indeed--the wise will know already while the clueless will get it sudden in a couple of days ;) Well, no big surprises nor earthshaking features are being here pitched then, just some small and otherwise humble improvements and fixes and what not. Nevertheless and not just for the record that is, it marks the day of a long overdue and severely procrastinated beta phase release. Whatever. It's dang official now: one step closer to omega, no doubt ;) Contrary to, maybe, newer generations, I always strive to say the least. As to say about literal face-value meaning, as written and read on timeless textbooks, it's all left in between the lines or, this part is the one I like most, left over as an exercise--in some kind of healthy masochism, perhaps :). No wonder, Qtractor 0.6.0 (byte bald beta) is now released! Release highlights: * Plugin automation high resolution option (NEW) * Plugin 'About' page (NEW) * Native DE dialogs option (NEW) * Follow play-head slack time (NEW) * MIDI RPN/NRPN 14-bit controllers input (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.6.0.tar.gz - source package (openSUSE 13.1): http://downloads.sourceforge.net/qtractor/qtractor-0.6.0-10.rncbc.suse131.s… - binary packages (openSUSE 13.1): http://downloads.sourceforge.net/qtractor/qtractor-0.6.0-10.rncbc.suse131.i… http://downloads.sourceforge.net/qtractor/qtractor-0.6.0-10.rncbc.suse131.x… - quick start guide & user manual (outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf - help wanted (on Qtractor Wiki ;)) 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: - New user option added: on whether to save plugins automation values with higher resolution as possible, using 14-bit NRPN: cf. View/Options.../Plugins/Experimental/High resolution plugin automation (default=off). - Generic native plugin dialogs now shows an additional "About" last page where authorship credits are due. - A new user preference option is now in place for whether to use desktop environment's own native file requester/browser dialogs (View/Options.../Display/Dialogs/Use native dialogs). - A bit of slack have been introduced to put "Follow Playhead" (aka. auto-scroll view mode) on hold, while doing in-flight selection edit moves. - Fixed some user interface related annoyances while on the MIDI Controllers mappings (ie. View/Controllers...). - Fixed port origin on MIDI RPN/NRPN 14-bit controllers input. - A discretionary plug-in unique identifier have been devised for when more than one from the same type are inserted on a bus or track chain, avoiding destructive clashing of automation data. - Horizontal scrolling shift+mouse-wheel direction now reversed. - LV2 Dyn(amic)-manifest support is now optional (default=off); cf. View/Options.../Plugins/Experimental/LV2 Dynamic Manifest support). - The following options, although decieved on View/Options... as global configuration options, were always and still are proper session instance properties: (JACK) Transport mode, MMC mode, MMC device, MIDI SPP and MIDI Clock modes, are now shown there reflecting the current open session state. - A couple of run-time circumventions have been hacked in, both strictly related to when NSM session management is in charge: 1) the new session template feature is disabled (was aborting initial NSM new client additions); 2) the native (as from the desktop environment eg. KDE) file browser/requester dialogs are disabled (were taking too long to list the current directory on first time invocation). - Update current automation/curve nodes selection while changing horizontal (time axis) zoom levels. - One liner's attempt to make it consistent behaviour on resizing and moving multiple selected notes or events while on the MIDI clip editor (aka. piano-roll; after a ticket request from Daniel MacDonald aka. danboid, thanks). - Introducing tiny quarter-note/crotchet/seminima/beat icon on all snap-to-beat selection items get a new icon :). - Corrected some audio buffering boundary conditions that were causing dead-loops/freezes while merging some audio clips. - Session auto-save period was chronically reduced to one third of its user setting; non critical but fixed now. See also: http://www.rncbc.org/drupal/node/772 See you all on LAC2014@ZKM-Karlsruhe! and have a happy new springtime, cheers! Enjoy && yet again, have (lots of) fun. -- rncbc aka Rui Nuno Capela

qtractor: Some instability with audio result from delay effect

by Zlobin Nikita

Hello. It is my first attempt of serious (rather massive than advanced) DAW usage - i used it in montage of own "playlist" from some favorite tracks, which is not to be published anywhere at all, just for personal fun. One track is very long, while in one place i needed only some specific parts, which i joined not very precise. And just for fine tuning of that i used one delay effect, whose name i don't recall - can only say, that it is dublicated with different max ranges, from which i used least available (0,01 s). And there is problem: resulting hearable delay randomly changes in some small range near of one phase. Did not research this problem better - just eliminated that fading.
