The VCO will almost certainly be the 4027-1 as it was the last revision and most stable.

The VCF is switchable between the "Moog Infringement" 4012 and the 4072, but I'm not sure if the 4072 has been corrected (you needed to change 4 resistors to get the full frequency response from it).

The problem with digital pianos for beginners is that even though they are cheap and easy to use, they can also be exceptionally expensive. So before you invest your hard-earned money, it is worth checking out other digital piano models which are more suitable for beginners .
