rectification : i made the design and mount the parts, my friend Nico the wood (the most difficult), and Julien the keyboard interface (the brain).. Nico sells superb custom furniture and the synth was a challenge for us . when i ordered 1 month later the back plate ...the bronze color was different from cs..next time i'll do with lexan . by the way all the furnitures and the synth were made of wood ..sand...sand...sand the corners...and 6 or more coat of lacquer...never again buton encoder from mte...thank you
