Some days ago i orderd a nektar se49, and it was really frustrating for me to use, i had to use the transpose constantly to go octaves up or down, I didnt know what buttons to use, eventually i resended it back, and am still waiting for my money to come, i have never used a midi keyboard before nor do i know how to play piano or a midi keyboard, i just want a perfect midi keyboard without using the transpose constantly, i have a pretty big desk
