What to do if you have a bunch of MIDI devices, but want to control them all from one Arduino? The simplest solution would be if you could program them all to respond to different channels. If you can't change them, though, Sebastian at little-scale offers a good solution. He is using a (de)multiplexer to control which device is connected to the Arduino hardware serial output pin, allowing him to address up to eight MIDI devices individually.

Makezine's permanent arduino advertising goes on my tits. Don't you have any shame?
BTW: Tell your editor that pressing the submit button once is enough to publish an article.

Hey there, Arduino is an open platform that's popular because it's easy to build on, make yourself, etc. Sure, we sell them in the Maker Shed, but you can also make one yourself, and all the board layouts and software are free and open source and cross-platform. We just as readily post cool PIC/Parallax projects, there just aren't as many these days, possibly because it's harder to get started on those platforms for beginners.
As for your second comment, to what are you referring? If you spot a problem on the site feel free to email me: becky@makezine.com

2nd comment is probably in reference to the almost daily double post of articles.

I designed two MIDI adaptors that work fine with the Arduino and allow for multiple device. These even allow for using the serial port on your PC at the same time including the boot-loader. The trick is to enable/disable the MIDI interface with an I/O line. Both the MIDI IN and OUT modules have this enable.

Yes a shameless plug but if readers need to control multiple MIDI devices....

Hey, those are cool, and I think pretty cheap, too. Thanks for sharing!
