Bitcrusher Bending Bidouilles. Hacking. Expériences. Découvertes. [Circuit bending] Une Présentation.url Ou l'art de détourner des objets électroniques le plus souvent sonores de provoquer des comportements innatendus tels que des sons bizarroïdes pouvant entrer dans des compositions musicales. C'est extrêmement facile, un niveau scolaire (collège) en électronique permet de pratiquer sans aucune difficulté! Pour commencer à pratiquer il vous faudra donc un peu de matériel électronique comme des pinces crocos, des boutons, des résistances, ainsi bien sûr d'appareils électroniques tel que de vieux jouets à piles auquel vous ne tenez plus trop. Ensuite démontez-en un et parcourez le circuit imprimé en connectant au hasard certains points pour y faire jaillir du bruit! Vous trouverez plus d'infos sur cet art dans les références ci-dessous. Reférences: Quelques liens en vrac: Deux livres recommandés pour débuter, ils sont complémentaires et en anglais technique (c'est à dire très abordable même pour l'anglophobe moyen):

Circuit Bent — Circuit Bent Instruments aaa.url Circuit bending Probing for "bend" using a jeweler's screwdriver and alligator clips Circuit bending is the creative, chance-based customization of the circuits within electronic devices such as low voltage, battery-powered guitar effects, children's toys and digital synthesizers to create new musical or visual instruments and sound generators. Emphasizing spontaneity and randomness, the techniques of circuit bending have been commonly associated with noise music, though many more conventional contemporary musicians and musical groups have been known to experiment with "bent" instruments. Experimental process[edit] A 1989 Kawasaki toy guitar used in a circuit bending project The circuit bending process has been developed largely by individuals with next to no formalised training in electronic theory and circuit design, experimenting with second-hand electronics in a DIY fashion, either with inexpensive keyboards or drum machines, or with electronic children's toys not associated with musical production.

Circuitbenders - Custom built electronic audio insanity machines.url Juergen Haible "Living VCOs " back to JH. homepage I already have a lot of different VCOs, from the ultra precise MOTM-300 to the lush, but not so well-tracking VCOs of my EMS-Synthi clone. Each VCO has it's benefits, the CEM3340's (partly under autotune control) are the "workhorses" in the OB-8, the Prophet 5 and my own JH-3, the Yamaha CS-oscillators are more on the "temperamental" side, but still playable without autotune (the 4 ones in my CS-50 stay better in tune than the 8 ones in my CS-60 ...). Features Drift and Noise and all that stuff Every few years there seems to be a heated debate how "stable" a good-sounding VCO should be, or shouldn't be. want to get rid of them, or add them externally, or deliberately keep them in your VCO. Audio Demo 1 13.5 MByte mp3 (First dry: just VCOs thru VCA. CS-80-Style PWM Like the Yamaha CS-80, the Living VCOs have a limited pulse width.

DIY Audio Stuff.url First, I must mention the best DIY pro audio board on the web, "The Lab" . My projects are/have been: Neve 1290 clone RCA BA31A clone My own preamp design Gyraf G1176 Jensen JE990 discrete op-amp - built one. Fairchild 660 rough clone - I built it by following half of the 670 schematic but substituting some tubes. LA4 rough clone - improved audio path, high-speed opto compression mode - haven't finished it yet My own SSM2081 feedback compressor design Neve 2254 Compressor - nice compressor. Gates M6629 Modifications. Figuring out how the Lexicon ARU chip works. Some of my observations on reverbs Processing on some reverbs I like This part is not for the faint of heart..... but if you want to build your own microphone capsules, here are a lot of bread crumbs here to help you along. Vacuum Evaporation for microphone diaphragms Some Strange DIY Capsules Other Capsules (Not mine) . DIY Copper Tube Mic . Making the M7 copy capsules . Debenham, Stebbings, and Robinson mic capsule . Tensioning a diaphragm .
