It depends on if you transpose or not. What we are talking about here is people who have to tranpose EACH and EVERY song because they can only play in one key. They can't or won't take the time to learn to play in every key, and they become dependent on that button for them to play.
For those of you who don't use transpose, don't start because it is like an addiction. It becomes easier and easier to hit that button, and at the same time it becomes harder and harder to actually sit down and become a REAL musician by learning every key.
The only acceptable time to use transpose is if it is up or down an octave. Sometimes you have to transpose a keyboard up an octave to get the very high sounds, and sometimes you need to transpose an octave lower to get those deep bass sounds. Other than that, don't ever, ever, ever use it.
I taught myself how 2 play,& still do because I feel that I will not limit myself as I would if i went to a local teacher because they would either teach me 2 be good in reading sheet music or a gospel 1, in playing in a or 2 keys only

My board has both transpose & Octave shift (2 octs), so I use the octave shift..as 4 transpose, I've used it in both 2 instances when I played @ church after disrupting the flow because i was playing in unfamiliar keys (& i was filling in bcos i don't play..we have 3 players [who all happened not 2 be there]).
2 can play in all the keys, but can't read /teach music, not even using the number system, so I can't rely on them 2 teach me, I just watch them play sometimes & pick up..theyve been playing over 10yrs.
The ada 1 is not interested in learning all keys...he's been playing 4 8years now...
I guess his concept is that so long as he can play any song @ church, no problem...no desire 2 learn..so I've left him..
I've now taught myself all the chords I've ever heard him play in that key (Ab) & if i learn new stuff, i upd8 him.
Adawise, i wouldnt say he ever sees himself on a piano/ organ..so good 4 him

As 4 me, it hurts 2 myself surpassing senior players because I learn a whole lot more than them bcos I can pick up from any key & apply it to all, whereas they just go blank because the other keys are a mystery to them.
Some are only helped by a v.good ear..
But there's stuff a good ear cant just pick up..lol.
summary: It's your choice whether 2 transpose / not, so long as the service flows

it's up 2 U whether U want 2 be the best U can
