/* USB MIDI Sync Box
|
||
|
|
*
|
||
|
|
* This example demonstrates how to change the USB MIDI
|
||
|
|
* device name on Teensy LC and 3.x. When creating more
|
||
|
|
* that one MIDI device, custom names are much easier to
|
||
|
|
* use when selecting each device in MIDI software on
|
||
|
|
* your PC or Mac. The custom name is in the "name.c" tab.
|
||
|
|
*
|
||
|
|
* Windows and Macintosh systems often cache USB info.
|
||
|
|
* After changing the name, you may need to test on a
|
||
|
|
* different computer to observe the new name, or take
|
||
|
|
* steps to get your operating system to "forget" the
|
||
|
|
* cached info. (TODO: wanted... can anyone contribute
|
||
|
|
* instructions for these systems)
|
||
|
|
*
|
||
|
|
* This example code is in the public domain.
