Thank you for viewing! m(_ _)m This is "Mr. Children SELECTIZON Full Score with MIDI DATA COLLECTION SMF STANDARD MIDI FILE MIDI PERFORMANCE SERIES_Mr. Children SELECTION". Especially with guitar, while you can change the pitch to some extent with WAV, it's impossible to change the chord forms. With MIDI, there are no range restrictions, and you can change chord forms while keeping the same patterns and rhythms." In the case of Mr. Children, there are many guitar chord strokes, and these are properly converted into MIDI data, so you can study these aspects with MIDI, or frankly, copy and paste them, adjust the chord tones and forms, and utilize them in your original songs. A full score is also included, so you can create higher-quality guitar parts to match your original songs. Shipping is planned via EASY60. Please note that we cannot offer any replacements, so please refrain from claims or returns. Also, this is a used item, so please refrain from purchasing if you are overly sensitive (I was once criticized for having a hair inside the box. I cannot accommodate such levels of detail). Thank you for your consideration.
