Yes, I agree. For the larger wedding/corporate party events, bringing a dedicated vocalizer rack is fine, but for the 45 minute set nursing home gigs & smaller venues (multiple gig/day type events) I need to travel as 'light as possible' with 'minimal equipment' for quick in/out setup and breakdown time.

If only the KN7000 included a vocal harmonizer of at least comparable sound quality as the one included in my budget priced Yamaha PSR2000 I would be happy. Sounds like this isn't the case though.
