Dispositifs | iOS MIDI
With iOS 4.2, an iPad and a USB Camera Connection Kit , you can now use MIDI hardware with your iPad! There are a few caveats: The device must have a USB connector (i.e. you can’t plug a MIDI cable directly into the iPad). In addition to this, you may have to setup your device slightly differently to make sure it transmits/receives correctly, ie with a BCR2000. It must be class-compliant – if you can plug the device in and it will work without drivers on a Mac, this generally means it is class-compliant. It must draw a amount of power, or have it’s own power source such as a power adaptor.

Sandy White - Xcom - Extreme Computing Festival
XCOM 2002, Extreme Computing Festival, London, June 9th 2002 When pressed before the event for a description of what Xcom 2002 was about, organiser Dave Green told me to "Imagine a village fete run by Daleks". I did and, well, you can imagine my disappointment when I turned up and found an event attended in the main by humans. Still that was well compensated for by the thrill of being able to skip an about-to-get-very-wet queue by telling the bouncer at the door that I'm a bloke that wrote a Spectrum game in 1983. I think I'll try that one again next time I'm queuing for a MacFillet of MacFish Meal and apple Macpie. The journey from the main door into the foyer was eventful.

Vous ne trouverez pas beaucoup d exemples de Réalisations sur ce site. Je préfère une approche plus générale, qui fait le tri entre les différents paramètres souvent contradictoires. Étant totalement indépendant de toutes contraintes commerciales, je privilégie les solutions relativement bon marché, et ne pousse pas à la consommation.

The delay time is set by a resistor connected to pin 6 (VCO pin). The voltage at pin 6 stays at 2.5V so the adjustable resistor is aparently setting the current for the VCO. I know of three ways to add voltage control to the PT2399. The method that I have used is an NPN current sink attached to pin6 of the PT2399.
