Pouets pouets dings and dings usual DX series are waiting for you. Always with the economy of algorithms on these sub-DX (DX21, dx9, DX27), which makes her even more devoid of interest.
Any computer with an emulation of FM synthesis can produce identical sounds the same as it is only the binary language from A to Z. (This is also valid also for the dx7)
No interest to avoid, you will gain up to you! (Especially the hp version looks even bulkier!)
