Minus one track by R-Mix

I have wrote the article in my blog, R-Mix software doesn't work as I wanted to be.
However, when I tried old music, minus one track was produced perfectly.
The reason why old music works is the stereotactic position of old music is very simple compared with current music.

So, I tried to minus guitar sounds from the move over which is my favorite music.
Then I played guitar by myself.

前にR-Mix は使えないと書きましたが、昔の曲はステレオの定位が非常にシンプルなので、簡単にマイナス1のトラックが作れました。 ジャニスジョップリンのMove Overという曲です。
