Hello Joselius,
It is easy to substitute the user styles with new styles.
But you can not store the styles for the PSR740 . This Va3 may be a great keyboard for you.
There are a thing's that Yamaha has done well
with the PSR 740.
1. The "one touch settings" on the Yamaha PSR series are great. 4 suggested sounds and multipads that musically interact with the style . Very cool .
#2. Groove feature on te PSR 740 is kind of unique. This feature allow's you to alter the feel of the pattern without drastically changing the style . Why they did not put this feature on the PSR9000 totally escape's me ????
#3. The 740 and 640 have a keypad. I think that this helps with selecting styles and sounds .
#4 . This Roland Va3 sounds like it has better spec's . However,the Roland navigation in my opinion has always been a
little awkward ( perhaps this has changed with the VA3 ). $979.99 is the price on the PSR 740 at Guitar Center in Towson Maryland. Good luck Dan O oneils4@home.com
helps . Good Luck
