Re: [LAD] youtube blocks LAC 2017 May 18 AM

by Thomas Cipierre

Dear LAC2017, I’m part of the LAC2017 committee, and was nearly all the time involved in the IRC #LAC2017 freenode channel as tcUJM (except one chairing session). For those who were there, I already replied that there was actually a real copyright problem, since Thierry indeed used copyrighted material during his talk. However, he has the right to do so, having all the documents needed on INA (standing for Institut National de l’Audiovisuel – which could be translated to Audiovisual National Institute) material, so we are currently solving this problem. Philippe, our LAC streaming technician is working onto this – but he needs some more time to edit videos, since he is needed on a lot of other projects in our university. We are sorry for the temporary side-effect on Harry’s brilliant talk. Thanks to all of you, I was thrilled being involved in this LAC and meeting several of you. I definitely look forward to seeing you again on forums, mailing lists and in future projects. All the best, Thomas CIPIERRE Phd. Student at Jean Monnet University (Saint-Étienne)

launch-step: a step sequencer for Novation Launchpads

by Kaspar Emanuel

Hey all, I wrote a MIDI step sequencer for the old Novation Launchpads. It has quite a few different scales (thanks to the tonal package on NPM), let's you change the sequence length on the fly and set lower velocities by holding down the pads. Demo: https://youtu.be/dS_x-FioqHM Code and installation instructions: https://github.com/kasbah/launch-step Cheers, Kaspar

Implementing software knob behaviour

by Christopher Arndt

Hi all, I'm currently trying to write a software MIDI/OSC control panel in Kivy/Python [1]. I want to implement a sensible knob behaviour but I have trouble getting this right. The general idea is: - Click (starting somewhere in the area of the knob control) and drag upwards/downwards (y-axis) increases / decreases the value. - Dragging left/right (x-axis) decreases step size of increments / decrements. - Each knob has a min/max value. My questions are: - What should I use as the reference point for finding the distance of the movement? The centre of the knob or where the first touch event occurred? - Should I apply the distance to the value directly or use the distance as a relative value (i.e. increment / decrement to the value when the touch started)? If the former, how do I prevent value jumps? - Or, to put it another way: how do you guys actually implement knob behaviour? Chris [1] http://kivy.org/

[ANN] Qtractor 0.8.2 - A Stickier Tauon release

by Rui Nuno Capela

And now for something ultimately pretty much expected: the Qstuff* pre-LAC2017 [7][8] release frenzy wrap up! Qtractor 0.8.2 (a stickier tauon) is released! Change-log: - Track-name uniqueness is now being enforced, by adding an auto-incremental number suffix whenever necessary. - Attempt to raise an internal transient file-name registry to prevent automation/curve files to proliferate across several session load/save (re)cycles. - Track-height resizing now meets immediate visual feedback. - A brand new user preference global option is now available: View/Options.../Plugins/Editor/Select plug-in's editor (GUI) if more than one is available. - More gradient eye-candy on main track-view and piano-roll canvases, now showing left and right edge fake-shadows. - Fixed the time entry spin-boxes when changing time offset or length fields in BBT time format that goes across any tempo/time-signature change nodes. - French (fr) translation update (by Olivier Humbert, thanks). Description: 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.

[ANN] Vee One Suite 0.8.2 - The Pre-LAC2017 Release frenzy continues...

by Rui Nuno Capela

The Qstuff* pre-LAC2017 [11] release frenzy continues... The 'Vee One Suite' of old-school software instruments, respectively synthv1 [1], as a polyphonic subtractive synthesizer, samplv1 [2], a polyphonic sampler synthesizer and drumkv1 [3] as yet another drum-kit sampler, are all joining the traditional pre-LAC [10] release frenzy! All available in dual form:: - 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. The common change-log for this second batch release goes as follows: - A custom knob/spin-box behavioral option have been added: Configure/Knob edit mode, as to avoid abrupt changes upon editing values (still the default behavior) and only take effect (Deferred) when enter is pressed or the spin-box loses focus. - The main GUI has been partially revamped, after replacing some rotary knob/dial combos with kinda more *skeuomorphic* fake-LED radio-buttons or check-boxes. - A MIDI In(put) status fake-LED is now featured on the bottom-left status bar, adding up to eye-candy as usual (applies to all); also, each drum element key/sample now have their own fake-LED flashing on respective MIDI note-on/off events (applies to drumkv1 [3] only). - Alias-free/band-limited wavetable oscillators have been fixed to prevent cross-octave, polyphonic interference. (applies to synthv1 [1] only). - A brand new and specific user preference option is now available as Help/Configure.../Options/Use GM standard drum names (default being yes/true/on; applies to drumkv1 [3] only). So here they are again! **synthv1 - an old-school polyphonic synthesizer [1]** synthv1 0.8.2 (pre-lac2017) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
