Quick hack to make NSX-39 (Poke-Miku) USB MIDI device to speak "mbed" from mbed which acts as an USB host.

Description of the project
This is quick hack to control Poke-miku (NSX-39) from mbed. The mbed acts as an USB host and controls USB MIDI device NSX-39. It speaks "mbed" if you send "s¥n" from virtual USB serial (connected to PC or Mac) or push SW connected to p21. It plays MIDI file "test.mid" on local file-system if you push SW connected to p22. You can find files that I have tested at the bottom. The standard MIDI file support is still preliminary. See TestShell.cpp for the hack. This program is derived from MIDI_BlueUSB (http://mbed.org/users/radiojunkbox/code/MIDI_BlueUSB/) by Radio Junk Box.
ポケミク(NSX-39)を無改造のままmbedから鳴らせるようにしてみました。mbedがUSB hostになって、USB MIDIデバイスのポケミクを鳴らします。mbedのバーチャルシリアル(USBシリアル)にPCからs\nを送るか、p21につないだスイッチを押すとmbedとしゃべります。p22につないだスイッチを押すと、ローカルファイルシステム(.binと同じ場所)に保存した test.mid を再生します。試したファイルは下にある test1.mid と test2.mid です。MIDIファイルのサポートはまだまだ完全とはいえません。
