ただまだ出たてだからなのか重大なバグがある。
このキーボードを使うと通知音やキーボードのタップ音などが消えてしまう。
モールス音を聞きたかったがこのバグで聞けなくて残念
同様のバグに悩まされてる方は再起動すれば直ります。再びこのキーボードを使おうとすると音は再び消えますが

### 3/5 — Sound isn't working, otherwise good

*2022-11-14*

The sound doesn't always match up with the keypresses, but otherwise it's pretty good!

### 5/5 — Love it!

*2021-03-30*

As a ham radio operator who knows morse code, I had never thought about using this kind of keyboard.  After setting it up, it is like using a straight key as timing of dits and dahs is critical.  Sending messages this way is lots of fun and great practice!  Very cool!

### 5/5 — おもしろい

*2021-01-05*

ぜひ エレキーに対応してください
