About

ただのクラシック音楽オタクが、最近流行りのアニメ・ゲームの曲などをオーケストラアレンジしたり採譜したりします。たまにクラシックの編曲もやります。DTM知識もロクにないまま割と無茶な編曲もしてると思うので、奮ってご指摘ください。作曲も挑戦してます。 I orchestrate music of Japanese game and Anime. I also make sheet music for piano(s), and often upload my composition. DAW: Musescore 2,3 Cubase artist Visualizing: MIDITrail 使用音源(Plug-in): Spitfire audio/ BBC Symphonic Orchestra(core)
