This is a first for me. Have been playing around with Midi for years since it cam out. I now think I have found real way to use it for me. Using my Technics KN7000 as the base keyboard. I went Midi Out to Yamaha PSR S770 Midi In. Split both keyboards to the same “F# 2” key. Using Fingered Chords for both and compatible rhythm patterns I tried ‘playing a song. The song is “Satin Doll” by Duke Ellington. Using both backgrounds together with fills and pattern changes I was amazed of how the blended to together so well. Taking a listen and judge for yourself? Hope you enjoy!
