音が出せない場合のオンラインレッスン

今回のコラムでは、日頃からヘッドフォンを使用しないと電子ピアノが弾けない生徒のオンラインピアノレッスン実現法「低コスト編の一例」をシェアしたいと思います。画像は情報シェアしてくれた大人の初心者生徒のAndrésさんです。

以下、彼からの情報です：

Dear Yumie,

I have solved the connection problem.

My main issue was the following: I am using a MacBook Pro that has one 3.5 mm headphone port and four USB-C ports. My electric piano has two 3.5 mm headphone ports as output.

I thought that connecting from the headphone port from my piano directly to the headphone port of my computer with an audio cable would be enough. However, and after some research, I found out that all of the new MacBooks like mine (manufactured after 2016) are not able to connect that way because the headphone port is designed only for output and not for input. Apparently, previous Macbooks (before 2016) are able to connect that way, but I have no way to verify that.

The way I solved it was by using first an audio cable like this one:

UGREEN AUX Nylon Mesh 3.5mm Stereo Mini Plug Male to Male Audio Cable for Car / Home

and a USB audio splitter like this one:

BUFFALO BSHSAU105BK USB Audio Adapter

I plugged one end of the cable to my piano and the other end to the microphone (pink) input in the splitter. I then plugged the splitter in my computer using a USB-A to USB-C adapter that I already had.

Now I am able to get the sound from the piano directly to my computer. I bought both products and the final price was a bit over 2000 yen, which I think it is an inexpensive solution.

I hope this info will help other students as well. However, I think that the solution depends mostly on the brand and manufacturing year of the computer.

See you tomorrow!

Andrés

ただ、何の線が必要かは個体差ありで少しリスキーですが、コストを抑えるというので参考になるかと思います。

あとは、Go-Mixerでも同じ感じで出来なくはないですが、これを買うのならあと数千円出せばヤマハのウェブキャスティングミキサー０３が買えてしまうので、オンラインレッスンには断然こちらが妥当かもしれません。この製品が届いたら実験出来るので、またの機会に情報をシェア出来たらと思います！でも、Go MixerだとスマホやiPadで手軽に出来るので、パソコンがなかったり操作が苦手な方やどこを重視するかにもよるとも考えられますね。生徒のEmmaとはGo Mixerでオンラインレッスンしてます。以下、Go Mixer＋スマホでEmmaが撮った動画です⬇️
