Electronics - News Circuitbenders - Custom built electronic audio insanity machines..........;.url gestion des enveloppes-volume-accordage - forum Formanta Polivoks Polivoks - Audiofanzine.url j'experimente cette façon d'accorder le polivoks. Je constate plusieurs choses : * La note non influencée par le clavier (dans la position intermédiaire entre voice1/voice2) de l'OSC2 est réactive aux 3 trims d'accordages dédiées (BAND 2 SCALE 2 PITCH 2). et à l'écoute la note jouée en mi aigue en configuration 1 VOICE ne sera jamais la même que le bruit pure de l'oscillateur dan cette position * si on gradue ces trims sur toutes leur course (minimum - maximum - position médiane (0)), il n'y a aucune corrélation logique entre ces mêmes trims et OSC opposé : si on mets chacuns des trims de l'OSC1 et 2 à 0, les 2 réglages n'ont rien à voir... mais alors pas du tout. Attention aux possesseurs de Polivoks : si le synthé et légerement désaccordé, surtout ne pas triturer les trims à outrance. * il y a comme une impossibilité à l'accorder justement (LA440 par exemple).... comme dit Hallucinoze, il vaut mieux y aller à l'oreille et ensuite accorder le tuning général avec...le Pitch général

Carrion Sound - .url http--library.thinkquest.org-16497-gather-cgi-bin-projects-1.gif.url ARM architecture ARM is a family of instruction set architectures for computer processors based on a reduced instruction set computing (RISC) architecture developed by British company ARM Holdings. ARM Holdings develops the instruction set and architecture for ARM-based products, but does not manufacture products. The company periodically releases updates to its cores. Current cores from ARM Holdings support a 32-bit address space and 32-bit arithmetic; the ARMv8-A architecture, announced in October 2011,[6] adds support for a 64-bit address space and 64-bit arithmetic. ARM Holdings licenses the chip designs and the ARM instruction set architectures to third-parties, who design their own products that implement one of those architectures—including systems-on-chips (SoC) that incorporate memory, interfaces, radios, etc. History[edit] Microprocessor-based system on a chip The ARM1 second processor for the BBC Micro Acorn RISC Machine: ARM2[edit] VLSI produced the first ARM silicon on 26 April 1985.
Patented Dual-Crossbar Architecture for 32-bit ARM Microcontrollers Silicon Labs’ Precision32™ mixed-signal 32-bit microcontroller devices use a patented dual-crossbar architecture that allows designers to choose peripherals and pinout placement without worrying about pre-set limitations and pin conflicts — simplifying PCB routing, minimizing PCB layers and ultimately reducing design time and system cost. Here's what sets the 32-bit ARM microcontroller apart from the rest: Put Practically Any Peripheral On Any Pin Using Silicon Labs’ patented dual-crossbar technology and a drag-and-drop GUI, developers can easily choose their analog and digital peripherals and pin locations for these peripherals. Last-minute changes are not a problem. The AppBuilder utility provides unprecedented flexibility in choosing the exact peripherals needed for the application, even with the smallest, lowest-pin count packages.
