I'm not an expert by any means but I believe Latino diatonic accordion styles are played largely on the pull. ...... I don't think you'd need to mash on the bass buttons to get out of having pulled or pushed too far.
of course they don't ":need" to
but why not if they don't have any bass reeds anyway and the
airholes are not blocked off
consider the reality of the lower end Mariachi players, their skill
level, the need to make it look like they are doing something
important, the mind numbing boredom of using only a few
notes ever and mostly as a rhythmic sound effect
hey, why not press a few Bass buttons for the air gulp
while you smile and keep your sombrero from hitting anything
I've always wondered if piano and chromatic players use the air button for anything other than closing things up to put the box back into the case.
that's about it, yep... have never needed to do otherwise.. maybe i have
been lucky and my accordions sound equally as good on Pull as Push,
with only the variations of Musette flavoring being complex in their
note and frequency interactions. Any time a note acted up pull vs push
i just fixed it asap if not immediately
it might also be that i am almost always well amplified, so slight variations
in pull vs push sound are less noticeable right off the bat as the music sails
away into the night sky
to me, you Diatonic player are performing a miracle keeping track of
where the heck the notes are and how to get to them in time..
my brain is stuck on every note every combination is here all the
time somewhere if i can just reach it, and beyond that i typically articulate
individual notes, sometimes every note in a melody, with the Bellows control,
so i just don't have any processing power available to think also about
direction or air gulping
