A lot of truth being spoken in the above posts..

If you want to be known as a keyboard player...play the keyboard..don't ever walk away from the keys and sing to pre recorded music...period!!

I would suggest play a few songs live (only)..maybe add a drum pattern...remember once you go to full sequencer or arranger play, there is no going back to .."look I am playing for real".

If you want to showcase vocals..just sing to laptop..but be prepared to be labeled a "karaoke singer"...that is pretty accurate..

I would rather have a decent vocalist sing while playing , even basic chords...for that legit performance.. That is why the guitarist comes off as legit..

Likewise an average singer , with better playing skills will be even more successful

Personally, I enjoy mostly just playing left hand bass, piano and a color sound with drums..and when I can ..my average singing

My second choice would be playing over SMF...with many parts muted..

My third choice would be arranger play...mostly for request like tangos, rhumbas, etc..and a request that I do not know well, and fullness of arranger can make it work..

My preferred first option I can play all night long...same with my second choice...
I would not want to use arranger all night long..I need more versatility ..

One more example..how to destroy your "band" image...and this is from personal experience the last year or two..
I have been slowly but surely trying to leave the band I work with....but not leave them cold without a workable solution..(I am hard to replace) ...I tried to warn them of a couple "bad" habits...singing to a commercial "karaoke" song while being booked as a band...I actually step off stage when they do this..."karaoke " singers are a dime a dozen, and there is no gain..when you can perform other tunes as a band..
And now a big no no...Take a gig that we do as a trio..drop the only key player in the band...fake keys with a non player that can't pick out a "C".....to recorded tracks with the absent players parts and play...Game over..you lose all credibility..Just another Karaoke act

I almost feel like skipping my remaining two months at the CrabTrap..yes the same venue where they faked the audience..

I am so much looking ahead..to my solo gigs..the way I want to play..
