Roland don't need to ASK about 76-ers, because they already have their sales figures to give them a clue. But a company that DOESN'T make a 76 in their arranger line is only going to get information by asking.
Which, of course, they won't (they've long made up their minds, whether the customers want them or not
This is kind of like me playing a REALLY bad version of "in the Mood' ONE time, and nobody claps, so from that point onwards I go 'Nobody likes bigband music, so I won't play any. These people that keep coming up and asking me for it MUST be some 'niche crowd', because I already tried it and EVERYBODY hated it. I will NEVER play bigband music again. OK, everybody, would you like to hear country, reggae or rock?!'
