[LAD] Hydrogen and Round Robin

by Aurélien Leblond

I just bought the drumdrops mapex samples to create a kit in Hydrogen... They are gonna be great with the direct/overhead/room functionaly in Hydrogen. The set comes with Round Robin and with a bit of thinking I came up with 2 possible design to get this functionality in. COMPLEX: - Add a list of samples in the Layer object ; the sampler will chose randomly one sample of the list when the instrument layer is played - GUI wise, when a user click edit/delete layer, a form will popup asking the user which of the sample he wants to edit/delete The pros is that data structure wise it is really clean: Instrument->Components->Layers->RoundRobin->Samples The cons is that GUI wise it's not very clear for the user what's going on, and it asks for more development. SIMPLE - Increase the number of layer per instrumebr to 64 - A check box is added in the instrument to active round robin - If round robin is activated, layers that share the same velocity range will be played randomly. If round robin is not activated, the layers that share the same velocity range are player simultaneously The pros is that the changes are very minimum to Hydrogen can be implemented in a couple of hours. In addition it is simpler for the user to see what's going on (checkbox and the visual of layers). So what do you guys think? I wouldn't mind coding the simple options, cannot wait to put all the samples i just bought into this! Aurélien

[LAD] jack1 unsafe with accidentally (?) internal exported functions

by Tito Latini

Hi, some internal functions are globals and I think it is not what you want (jack2 seems ok). For example, a naive way to forbid the creation of other jack clients is: # tested with jack 0.124.1 gcc -ljack private_club_mode.c ./a.out # prints "JACK compiled with System V SHM support." echo $? # 0 jack_lsp # no more clients please, segfault (jack_client_open_aux) /* private_club_mode.c */ #include <jack/jack.h> int jack_register_server(const char *, int); int main() { return jack_register_server("umpa", 0xDADA); } Tito

[LAD] Fwd: AES69-2015 standard for file exchange - Spatial acoustic data file format

by Jörn Nettingsmeier

This was just announced on sursound. Might be worthwhile to adopt for anyone working with spatial audio datasets and files... -------- Forwarded Message -------- Subject: [Sursound] AES69-2015 standard for file exchange - Spatial acoustic data file format Date: Sun, 15 Mar 2015 16:13:47 +0100 From: Markus Noisternig <Markus.Noisternig(a)ircam.fr> Reply-To: Surround Sound discussion group <sursound(a)music.vt.edu> To: Surround Sound discussion group <sursound(a)music.vt.edu> Dear Sursounders, We are pleased to announce the recent publication of the AES69-2015 standard for file exchange - Spatial acoustic data file format. See also the AES press release at http://www.aes.org/press/?ID=293 <http://www.aes.org/press/?ID=293> The new AES69-2015 standard defines a file format to exchange space-related acoustic data in various forms. These include HRTF, as well as directional room impulse responses (DRIR). The format is designed to be scalable to match the available rendering process and to be sufficiently flexible to include source materials from different databases. This project was developed in AES Standards Working Group SC-02-08 and standardizes the Spatially-oriented format for acoustics (SOFA), which aims at storing and transmitting any transfer-function data measured with microphone arrays and loudspeaker arrays. See http://www.sofaconventions.org/ <http://www.sofaconventions.org/> for further information and ongoing format discussions. Open source application-programming interfaces (API) for Matlab, Octave, and C++ are available online at http://sourceforge.net/projects/sofacoustics/ <http://sourceforge.net/projects/sofacoustics/> All the best, Markus and Piotr -- Markus Noisternig Acoustics and Cognition Research Group IRCAM, CNRS, Sorbonne Universities, UPMC Paris, France Piotr Majdak Psychoacoustics and Experimental Audiology Acoustics Research Institute Austrian Academy of Sciences Vienna, Austria

[LAD] [ANN] Vee One Suite 0.6.1 - A fourth beta release

by Rui Nuno Capela

Hi, The 'Vee One Suite' of this 'old-school' software instruments, also self-indicted as the gang of three usual suspects thou being: synthv1 [1], as one polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as one drum-kit sampler, now released into the world, yet still beta. Not much of any audible changes I must say for this so called fourth beta release though it goes as follows: - Added application description as freedesktop.org's AppData. - Introducing LV2 port-groups (as proposed by Amadeus Folego aka. badosu, thanks). - Improved envelope widget nodes click-and-drag precision. - Introducing a brand new user preference on eye-candy: cf. Help/Configure.../Options/Custom style theme (applies to the JACK stand-alone client only though). - Envelope and filter now rendered with anti-aliased lines. - Fixed a Qt5 FTBFS re. QHeaderView::set[Section]ResizeMode(). There's no surprise as it's all made available in dual form, 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. 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.

Your asound.conf already does this. To allow a playback device to be shared, you need to use dshare or dmix. (dshare allows to use _different_ channels; dmix allows mixing multiple sources into the same channels.) Your asound.conf does not do this; it uses "hw" instead. Regards, Clemens
