Mother 1.5 Beta released

mother_icon

I updated the Mother library, to make it compatible with the latest version of Processing (2.1.1), and to add a host of new features.

For more info on how to get it and what it is go to it’s dedicated page: www.onar3d.com/mother

Let me know how it works for you and do send me any examples of work you’ve made using it!

New features in version 1.5:

  • A new type of visual synth is now supported: effect synths. These do not draw any geometry themselves; rather, they modify the image created by previous synths, much like FreeFrameGL plugins usually work.
  • Blending, transparency parameters are now automatically implemented for all synths.
  • An experimental feature, which may need some refining, but seems to work for my use-cases: while previously the hierarchy of synths within Mother was a stack, now it is a tree: this in practical terms means you can apply an effect synth that only applies its effect to the synth it is stacked over.
  • A new example has been created to demonstrate the effect feature, and the new tree hierarchy.
  • Each synth now draws into its own off-screen buffer. This requires more graphics card memory, but allows for all the above new features.
  • OSC Address patterns for addressing synths are now slightly modified, meaning you will need to update your previous controller programs: while before the address pattern was: “/Mother/Child/YourSynth01/ItsParameter”, now it is: “/Mother/YourSynth01/ItsParameter”. Simply put I did away with the “/Child” fragment.
  • FoetusParameters now automatically handle OSC message receiving, in the normal case where a single value is set. Typetag strings with more than one parameter, or more complex handling than simple value setting, still requires manual handling however. Please refer to the examples for this change.

Mother 1.0 Beta is up, Processing 2.0 compatible, and much easier to use than before!

motherExamples

I have now updated my Mother library for it to work with Processing 2.0, and took the opportunity to also address the usability problems the previous version had. This one should be much easier to get started with!

If this is the first you hear of it, Mother is a standalone host for running multiple Processing sketches in parallel, and mixing their output, in a manner analogous to VJing (more info and videos at www.onar3d.com/mother/).

I’d greatly appreciate if you would give it a try and let me know how you get along, treating this release as a Beta for now!

It works fine on Windows 7 & 8, 32bit and 64bit, and on OSX.

Getting started instructions are at the top of the “Mother Documentation.pdf” included in the library zip file, along with more info on the library.

For the previous version I did get complaints about it being convoluted to use, particularly for Processing users not advanced enough to work with Eclipse.

I have here done my best to address this issue, do please let me know what you think, what errors you run into, and how you would suggest I further improve the library!

Somehow I’ve ended up doing radio in Greek :)

 

Disco Deewane

This is a two-part series, on the subject of how technological developments have altered the roles of musicians.

The non-Greek speakers among you might get bored from all my talking, I hope at least those that do understand the language enjoy listening to it :D

The first and second episodes can be found by fllowing the below links:

New research papers available

Two new research papers I’ve been working on are now available to view, while another few are in various stages of publication / completion and will too be linked from here once they’re publicly available. The new papers are:

Using Music as a Signal for Biofeedback

Ilias Bergstrom, Sofia Seinfeld, Jorge Arroyo-Palacios, Mel Slater, Maria V. Sanchez-Vives, International Journal of Psychophysiology, 2013

and:

Drumming in Immersive Virtual Reality: The Body Shapes the Way We Play

Konstantina Kilteni, Ilias Bergstrom, Mel Slater, IEEE Transactions on Visualization and Computer Graphics, 2013

For abstracts and links, please refer to my publications page.

PhD thesis now available online

UCL has now posted my PhD thesis document for online download here.

The description of my PhD work is more up-to-date in this document than in the academic papers that preceded it, so if you have come here after having read my articles, you will most likely find my thesis to also be of interest!

Barcelona

Just a quick note to inform of my geographical relocation to Barcelona!

Invited seminar at Queen Mary

I was invited to present a seminar on my PhD research at Queen Mary University’s Centre for Digital Music, on Monday the 8th of March, at 16:15. Entrance is free and accessible to all. For more information, and information on how to get there, please refer to this link.

A presentation of a novel, entirely custom developed system, for facilitating the live performance of Visual Music / abstract animation. The hypothesis is that by using musical instruments as the primary user interface for the performance, we may usefully re-map the embodied/enactive knowledge that musicians have of their instruments. Musicians may then perform live visual music, taking advantage of the expressivity their instruments afford them. For this work, a new control data mapping strategy had to be developed, of ‘Mutable Mapping’, which entails manually manipulating the mapping during a performance, gradually altering and re-routing digital control data.

Visual music survey

In order to find out which one of two different visual music technologies audiences prefer, I have created an online survey for comparing them. Please take part by filling it out, and when I have enough responses I will post the results here!

The survey is reached using the link below, and should not take you more than 10-15 minutes to complete:

www.surveygizmo.com/s/204226/visual-music-1

I have not disclosed too many details now, because that may influence the way you answer. Rest assured I will post all the details when the survey is closed.

Thanks!

EDIT: I have now compiled the results and written up a research paper describing them, which has been submitted for review towards publication in a journal. As soon as the results have been published, I’ll also post a summary here!

Mother 0.6.1 minor update released

0.6.1 is only a minor update, adding no new functionality. The only change was to re-compile the Foetus library so that it is also compatible with Java 1.5, as on OSX there were reports that also recent versions of Processing was running on JVM 1.5. If Mother 0.6 is running fine for you, there is no need to get 0.6.1.

Mother 0.6 released for Windows and OSX

Thanks to the continuing involvement of Krzysztof Golinski on the project, developing of Mother has now sped up a bit, hence the increased release frequency!

New features in Mother 0.6:

  • Small mistakes fixed from previous 0.5 release: Waltz synth example was not working, and I failed to mention in the documentation that you also need the Shapetween library to develop new synths.
  • More comprehensive secondary screen support introduced.
  • pre(), draw(), post() and dispose() methods are now called properly in synth libraries.
  • It is no longer necessary to put an Init() method in sketches intended as Synths for Mother (Finally!).

As always, you can download the latest version from the Google code repository!
