I've been composing a few tunes that exploit
that anomaly. It’s really handy in riffs where
you don’t want the pitch to change with bellows
direction. (We’re talking about the lowest pitch, right?)
I think the reason most people dont use the number one button is due to the fact that many never take the time to learn how to incorporate it into their playing. I can off hand think of two songs in which Aldus and Octa both use the number one button. Its a pretty essential button for some creole and zydeco players too.I know a few other players like jason bergeron, joel martin, mitchell cormier and his father nolan cormier love to work it into their songs. I like to use it as much as possible.
