I've been writing and recording my catalog of songs using Yamaha Arrangers for years now. I don't use my arranger to prepare a "simulation" to let a group of studio musicians play the song... but if money were no object, I would give that a shot.
Now that Yamaha has finally begun to create/utilize better sounding instruments (guitars, mandolins, etc) it is much easier to "pitch" a song. I don't consider myself much of a success but with the arranger (no matter which brand you use) song-writing is a much easier process.
Thanks for sharing the video, Donny.
