Congratulations!!
The Yamaha DGX-670 is the best 88-key weighted action Arranger Keyboard one can buy at $799. This model sets a new benchmark on the price/performance map. This is the logical and sensible purchase for a beginner.
I believe Yamaha was forced to reimagine their DGX line after Casio introduced their CDP-S350 88-key weighted action Compact Digital Piano with Arranger functions for $549.
Competition is great for the consumer.
Our local Sam Ash store is selling the DGX-670B model like hot cakes. The customers come in and play on the Yamaha P45, P125, Casio CDP-S350, Roland FP-30X, Casio Privia PX-S3000 and pick the Yamaha DGX-670B.
This fun video by
Gabriel Aldort gives a good overview and explains the
new features.
The only feature I wish that was included is a touch screen or a way to mirror the display on an iPad where you could control the instrument by touch.
