This is a set of two books from the DTM Handbook series: Drum Programming and Horn & Strings Programming. These books are for those who want to learn DTM (Desktop Music) from the basics. Both are published by Rittor Music and supervised by Genichi Shinoda. - Title: The Best Drums Programings - Title: The Horn & Strings' Programings Especially, The Horn & Strings' Programings is a rare book with a limited distribution. It is recommended for those who want to add horns to their band sound using MIDI, or for those who want to learn classical string arrangements. These books have been stored on a shelf since I purchased them. They are old, so there is some aging, but the inside is clean. As these are used items, there may be minor stains and scratches. Please consider this before purchasing. *Please refrain from purchasing if you are concerned about minor details. Thank you for looking.
