MIDI IN, OUT, THROUGH
The use of the menus are clear and well structured.
I had a DX21 before, editing is native! lacking a publisher via a PC or MAC tool.
The manual I have ever had, for there against an online help on the display.
The sheets are beautiful, the piano is not the entire operation of the technology of the keyboard they are limited to two octaves!
The control is very nice and accurate cons (Velocity and Afertouch very well.
I have this keyboard for 15 years, he is my companion composition.
Apart from a note that "COAC" The A2 is very robust.
I use mainly keyboard master and multisplit assignable Midi came in handy.
Very good dynamic and touch after touch, it lacks a touch heavy.
After 15 years, I do not regret my purchase.
