Roland AE-05 連接Linux

拿到一支Roland AE-05(Aerophone Go), 從說明書看，它可以透過藍牙跟手機連接，
然後利用手機來設定AE-05，或是用手機接受AE-05來播放額外的MIDI音源，因為
AE-05內建只有11種音源(包括一組打擊樂器)，如果用手機可以播放額外幾十種音源，
不過這時要把AE-05本身的音量關到零。

首先遇到的問題就是手機無法連上AE-05的藍牙，裝了Aerophone Go APP也是連不到，
經過確認是安鳳無法連AE-05，只能用哀鳳或哀Pad連！(需要iOS 11或以上)

把AE-05透過USB線插到電腦後可以看到VID/PID

以上確認Linux能夠看到Roland AE-05的device, 再來檢查一下是否能收到AE-05送過來
的訊號？

aconnect -i
client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
client 14: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 20: 'AE-05' [type=kernel]
    0 'AE-05 MIDI 1    '

指定 port 20
aseqdump -p 20

這時按AE-05的鍵或是吹氣出聲，都會從螢幕上列出一大串MIDI的值

還未解決的問題是能否吹奏AE-05 讓腦裡來播出各種MIDI？
