True of course. I called it "cheating" because whoever wrote the music likely intended bellow shake to be performed, and the "tape-reverb" was not really designed for creating repeating notes... But whatever works works.Interesting notion what we view as 'cheating' (and why) and what is seen as taking advantage of later technology to achieve one's aims. A whole philosophical debate there, I think! Shall I take out my manual gearbox car today, or 'cheat' and take the automatic...? There's some sort of threshold of perception involved, I suspect, and it may change over time.

I would not accept the analogy with the manual versus automatic gearbox, because both are used for the purpose they were intended for. The echo setting on the accordion mimics the tape-reverb that was at one point popular. It was not intended to repeat notes at close to the original volume. So it's not used for its original purpose. But it still is a neat trick!
I sometimes use "tricks" in my acoustic accordion recordings as well, like partly closing a register slide while playing to simulate tone-bending that is normally done using the key, or partly closing the tremolo-M-reed to reduce the tremolo (without changing to a different accordion or changing the tuning)... Other than that my tricks are written in the score (of the arrangements I make myself) like using the H voice instead of a non-cassotto M voice, or L voice instead of M, doing "diviso" to make things easier (when it's written), and my most commonly used trick for obtaining "perfect" recordings is to do many takes and select the best take for each fragment! So in some sense there is a lot of cheating in my recordings...
