guitpic1 ... I recently started doing some gigs with a female vocalist - her gigs, her karaoke equipment - I bring me and my mic ... Some of the backing tracks are great, some a little less ... I find it totally different from using my KB (Pa900) ... I feel that I have more flexibility with the KB, even if I am using my own backing tracks, 'pro' midi files or mp3, or on board styles, and I don't see that much difference in 'relating' to the audience ... all I notice is that I haul a lot less gear when I work with her ...
For most of these gigs we are being paid to entertain for an hour, so whatever works, use it ... I still prefer to use my KB, but then, I would also still prefer playing with a live band ... but then, that's just me ...
