Scott, did your fills change to straight 8th?
Here's the "PianoBoogie" conversion I did with my Tyros 2 (as in addition to the T4, I still have my T2 too).
The converted to straight 8's 'fills' sound ok to me. Montunoman, have a listen & let me know what you think.
btw: for anyone interested in purchasing my in excellent working condition '
fully loaded' Tyros 2, PM or email me.
