” Yamaha DX21 MIDI Digital Programmable Polyphonic Synthesizer.
Comes in a 5 STAR flight / transport case which is in top condition (and the keyboard will be shipped in this).
I have tested all I could on this keyboard :
The screen works ok – there are some black bits at the top and bottom of it that I have tried to show in one picture.
But it does not affect the area where the text is displayed.
All the piano type keys are working properly
All of the green buttons work – i.e. they make whats shown on the screen and the sounds change.
The volume and balance sliders work, and so do the modulation and pitch wheels
The headphone output and A&B outputs are producing sound.
I have not (and cannot) test all the other sockets at the back of the keyboard.”
