Yes, unfortunately (please see my earlier post to this thread with a more detailed explanation), the G70 does only a fair to poor job of playing unmodified SMFs compared to a G1000.
BUT.......... read my post again. Roland provide the fastest, easiest way to correct this problem. Let's face it, if all you want is a new keyboard that sounds EXACTLY like your G1000, why change at all..........?
If you want a new keyboard that sounds seriously better, you are gong to have to put some time in tweaking the files to make it sound as good as it can. Who, in their right mind, wants to run an SMF through (for instance) a MotifES and NOT use the best sound for each part? Well, OK, you're going to have to do some work.......... But doesn't the end justify the means?
Please don't over-react to my 'lazy' description of this problem. I fully understand that not everyone here is a full-time musician, and am sorry to describe the problem in such a confrontational way, but in all professions there is the 'easy' way and there is the 'best' way. The ones that rise to the top are the ones that take the path less travelled........
Once again I bring up the point that ANY SMF needs tweaking to sound it's best on anything but the original equipment...... but how easy does YOUR manufacturer make this process???
I argue that if your keyboard was as easy to adjust as a G70, you probably WOULD take the time.............
