I'm working on a homemade Midi controller using an UNO and Windows 7. For the moment, I've just been trying to get one of these two examples functioning: http://arduino.cc/en/Tutorial/Midi http://itp.nyu.edu/physcomp/Labs/
Since I'm not yet trying to run Midi straight through USB, I need software for virtual ports and mappings. Nearly all the searching I've done points to this same website: http://www.spikenzielabs.com/SpikenzieLabs/Serial_MIDI.html
Unfortunately, the "Midi Yoke" that I'm told to download is out of date http://www.midiox.com/. The installation keeps "getting interrupted" and crashing when I try to install it on Windows 7.
Has anyone here gotten other free virtual Midi ports working with Arduino?
