Hi Don,
A bit late to reflect on this perhaps but better late than "dead on time".....
First of all they all sound quite impressive thanks to the guy hitting the notes and the keys, that much should be clear.
And as Donny and many more would maintain there is no accounting for tastes ( though Tyros 2 is stretching it a bit.. :)), but personally I think your recordings/renderings here are the best on the Genos and the PA4x, not surprisingly so as they are supposed to be the best I guess, and the most expensive...
There is one caveat though and I am surprised that Fran after listening again came out with the SD7 on top.
Now as you may know I have had a Ketron SD7 for approx. two months now and overall I am quite pleased with it, notwithstanding its shortcomings. I guess the SD7 comes somehwere in between the TOTL and the MOTL models and as such one would not expect it to compete with the big boys.
As regards your recording here with the SD7 I can only say that it does not do justice to the SD7, despite your perfect and professional rendering of the song. Believe you me it can sound so much better on the Ketron. Drums and bass have been praised by all and sundry, and many natural righthand sounds are very good as well. The problem with the Ketrons is that they rely a bit too much on previous stocks of styles, average guitar sounds in the accompaniment section ( as for strings as well)...Furthermore the tweaking and programming that can be done on the SD models is almost too much and discourages many from even starting.... The recent demos by AJ on the SD9 have shown how much can be achieved by playing these models.
The PSR970 and the Roland E-A7 are very good arrangers for their price range though.
Thanks for posting,
regards
John
