C programming for Arduino

Sep 7, 2012

This is now decided. This is the title of my book that will be published by Packt Publishing on paper, ebook and other electronic formats for iPad and more.

As the author I decided to propose this concise and easy title instead of a longer one. There will be a subtitle. I didn’t decide about it yet.

I also created This is only one page todat, but it will be improved and I’ll probably put something like a forum mid 2013.
You can subscribe on this page to the newsletter which is the BEST way to keep informed about all news, coupons and I don’t know what !

I invite you on the official facebook page of the book here:

Did you know the [bon]ome ?

Jun 9, 2012

One day, I needed an RGB monome clone.
It was early 2008. WOW, sounds like a time where there still were dinosaures =D

I built it from scratch using Arduino board.

I’m re-publishing it today because it seems you’ll hear about me & arduino in next months.
I cannot write why, what, how, but you’ll be happy for that, for sure!
Here is the document on but here it is for you now :

THE BONOME controller features:

– 8×8 buttons
– 8×8 rgb leds
– arduino diecimilla based (Atmega8)
– customized serial protocol based on monome 40h
– MIDI or OSC through a specific python server for RGB handling


I’m using Ableton Live software since several years. IT IS the only software I used which provides a real interface to play intuitive music performance.

I own a BCR2000 that I use for volume,fx & mute. The only thing I’m watching on my screen during music live performance is : clips matrix.

I found guys that hacked some python scripts provided with Ableton Live. You can find it here. It seems to be work in progress too, but it works fine with Ableton Live 7.0.1, OS: XP SP2.

Mobile Mood Machine for iOS

Jun 1, 2012

Here is my latest iOS machine.
This is my 3rd application on App Store after:
Mobile Particles
– Digital Collisions for iPad & iPhone/iPod
The Droner

You can download it here

The main purpose is to make the most amazing & efficient mood machine ever.

Because Less is More, I worked and removed progressively a lot of features to keep only the main interesting from an aesthetic & zen point of view.


Here is the very first video demo:


It includes around 7 moods and more are coming.

Each mood can play (or not, as you’d prefer) unique soundscapes  designed especially for this application by me.


Mobile Mood Machine is one of the strangest iOS application amongst a lot of music application for iPad.

Mobile Mood Machine provides a playground you can touch with your fingers.
Rules are really easy and minimalistic:
– touch the screen to create spherical creatures popping out sine waves sounds
– the more the touch is made at the top, the more the creatures pop out high pitched sounds
– choose a Mood which consists in color gradient, sequences rules, scale
– choose to listen especially designed soundscapes in the background or not
– adjust the delay and the effect of time over the age of those digital creatures
– enjoy !

Minimalism, Zen & Quietness are the main words that could describe this iOS application.

The Mobile Mood Machine ‘s engine works with circular buffers recording til 8 sequences represented by 8 colors.
Each sequence is repeated according to specific rules related to the current chosen Mood.
Some Moods are minor, some are major with a lot of time between sequence repetitions, some are hypnotically repetitive.

You can choose to make creatures becoming old. In that case, they will progressively disappear and their sounds will have a bigger attack til their end, when they will completely disappear.
Some Moods make them to be old faster, or slower.

Here are some possible uses:
– walking in the street
– being in the train
– beginning to try to sleep
– before going to an hardcore meeting
– together with your loved one relaxed

This promising system have already a nice roadmap for the next months.
Especially, The mode Near Sleep Experience will provide a nice way to enter in sleep progressively with a VERY long fade out from the moment when you set up the global time of fading and the last notes played.
This is a nice digital creature holding your hand til the dreams’ world.

Tech Café à Marseille ?

Apr 6, 2012

Hello à tous et surtout aux marseillais!

Je voudrais vous proposer des moments informels d’ open discussions autour des technologies que l’on utilise.
Pour ma part, on peut parler de:
– openframeworks & C/C++
– audio DSP
– arduino et arduino-like et électronique
– Pure Data & Max6
– Stratégie de développement agile pour sound applications sur  iOS
– Ableton Live / Max for Live / Reaktor et Sound design

mais aussi
– ambient music
– entrepreneurship moderne
– vie d’artiste digital
– zen coding
et + + +

L’EVENT est ici:

Si vous êtes intéressés, sachant que je bosse souvent à l’extérieur (café en ville, coins sympas), je peux vous proposer un time slot de 2h par semaine sur lequel vous venez, on fait connaissance, on teste, on bricole nos laptop etc.

Digital Collisions 1.0

Mar 26, 2012



Just after mobile particles 1.0 has been APPROVED by Apple, I submitted this other one.
I may be in a huge creative mood way these days.

Already featured on MATRIXSYNTH & SYNTHTOPIA & DISCHORD & MUSIC RADAR & iOSNOOPS, I’m very happy that you appreciate my apps.

Check Jordan Crudess‘  video (thanks to him, he made that video, not me)

Digital Collision is a unique sound generator based on physics collisions algorithms.
It can produces real nice sound textures from the most clear to the weirdest granular.
The sound engine is a polyphonic tone generator.

It is the second application designed by Julien Bayle (known as protofuse on the digital electronic music scene)

Touch the screen to create particles.
Each particle lives its own life, making sounds while bumping walls or meeting the other particles.

By clicking on Menu, you can control particles lifes & sounds.

Zen defines the quietness of particles.
Autogeneration is a special mode where particles are generated automatically, sometimes.
Birth defines the amount of automatically generated particles in Autogeneration mode.
Delay Amount is the percentage of delay fx, Time is the length of the delay,Feedback is the percentage of output sent back inside the Delay, Symmetry is the most strange parameter involving stereo disorientation.
Filter Freq control the center frequency of the global BandPass filter & High Notes is the Highest Note produced (MIDI notation)

You have to test the Noise.

It produces an unique & nebulous collision soundscape & you can control the amount of nebulosity.
