I've been using the Yamaha PSR series for years finishing up with the 9000PRo plus VM card. Yes I missed the Yamaha at first but having had the G70 for a month and spent that amount of time doing my re-programming and setting up, I'm now very much enjoying the G70.
I admit I still have a Yamaha but resisted the urge to play it until now and I still prefer the G70. I hasten to add that I've updated to V 1.10 and appear to have no bugs.
I find that the G70 requires a lot of dedicated attention to remember how to do things especially when your getting near the pro-end or concert end of performing but, on relection, this was the case with the PSR's.
Today is my first 'outing' playing outdoors with a pair of outputs of some 500 watts each. If you're interested, I'll let you know how I get on
Regards Derek Miles.
