1- Dominick not Donald

2- Fills are fine, they work a bit different then Yamaha Pa800 is doing a fine job, so far I'm really enjoying performing with it & still learning its ins & out as I go along.
3- Panic for a gigging musician with a defective unit is imperative that is is remedied immediately, Yamaha has a good track record, lets hope they make this right asap.
4-Ian as far as the 76 keys which Im so glad KORG is addressing with the release of their new Pa units will be a consideration ....maybe more so for a studio piece & backup at this time.
5- Whats your opinion of the Yamaha stage-pass PA system as far as power, coverage, flexibility, & of course Sound?
