Surely, playing a new instrument for the first time is like putting on a new pair of shoes for the first time, one long walk will not give the right impression!
Manufacturers will always be quite unable to satisfy the demands of all customers but at least, in Roland's case, in the G70 they have given us the facilities to 'bend' things to suit just about all of us.
I have had all the Yamaha top end arrangers except the Tyros, I have heard the Tyros played by many performers but I thought that it differed very little from my PSR 9000PRO both in the sounds and the styles. Certainly looking at the spec, the G70 has more to offer.
I have now bought a G70 with the latest upgrade v 01-06 and it pleases me. I hasten to add though that I have had downcast feeling whenever I have bought a new machine and I go back to the days of the D50, D70, plus all the synths that followed and that's many of them, I've been changing about once a year for 30 years.
This G70 I find complicated but only because I have to get used to it, I cannot easily find or remember what buttons to push, I get impatient, I get frustrated with the thing, I take a rest and have a think and go back to it with the thought it mind "What do I want to achieve" I stick with it and I stop acting like a kid dashing into a toyshop and touching everything.
I've bought it, I'll keep it' and I'll sort it out to my own entire satisfaction because it will allow me to do so.
