Nice combination.... But the biggest challenge is the Korg Operating system ( Genos is sooo easy in compare)
It's a great combination, no doubt. 👍
PA5X has a brand new OS and is very similar to Yamaha Genos / Genos 2 in many ways.
Korgs new OS should not be the biggest challenge for the Yamaha users, and if there is a bit of PC knowledge in addition, it's 'easy as that' to understand, operate and navigate.
