Am I happy with what I currently use S910 on stage every day/night to make a living?..YES...Do I want to see Yamaha make some changes in future MOTL units,..YES......will those improvements be realized even though they would maybe be just for my needs as a performer and not for the masses?..Who Knows? At this time I know the Tyros line after having the T1,T2 is not for me not because of sound, but layout and not needed real estate issues...Korg Pa800 was to me although some really nice features like the Songbook, TC VH unit, Mp3 player, Backing track seq,...I still didnt like the antiquated PA Folder system for editing to many steps, and the key-bed response for me was a bit spongy and less then stellar, the S910 even though super lightweight has a better action that I have compensated my style of playing to accomaodate...Roland G70 excellent arranger in So many ways ...great VH, super key-bed, phenomenal editing capabilities, makeup tools, maybe a bit smaller all around, 10 lbs lighter, and add a Mp3 player and for me even with the 76 keys would be a super arranger for live performance..Sd1/Sd5/Midjay.....
I noticed playing them except for the RIFF mode on the SD5 pretty much the same sound/styles and OS, size & build was nice, SD5 Joy stick very funtional, Midjay was the most versatile UNIT with really kool features that I enjoyed thats you caould play all modes at the SIMUTANEOUSLY with seperat slider controls, but who wants to carry and hook up modules?...jury still out on the Audya 5 as I haven't played one yet, hoping to do that and A/B with T4 in a few weeks....So I remain with my trusty S910 and in no rush to move on....the Digitech VR also is my main VH unit when needed...meanwhile dig in to what you already have explore new things, try to create some styles from scratch,
re-assemble a few parts to make the style your own....and who know down the pike something might come along you can salivate over....
Have Fun....I know I am!!
