It all depends on the type of 'diatonic' box. On a one row , particulary of the 4 voice veriety the air button is the only way of controlling air supply as there are no notes in alternative directions.
on a 2 row DG box which is pro;bably the most popular tuning in England some ply more or less exclusively 'on the row' to get maximum lift and bounce for dance music whilst others indulge in a degree of cross rowing to improve?? bass harmony or to bring about a change in bellows direction.
French and German players who generally favour CF of GC boxes generelly use both rows and are more interested in getting something like decent bass harmony than in using the bass to drive a rhythm.
3 row boxes eg ADG. GCF provide some more alternative direction notes and usually haave 12 bass ( rather than the 8 of a 2 row)
The similar but different semitone boxes i.e. 2 rows tuned a semitone apart eg BC, &CC# are in fact chromatic but some keys are quite difficult. The bass is to put it politely 'of limited use' and indeed many players of Irish trad music don't use the bass at all
Then there are the large 'British Chromatic ' 3 row diatonic boxes as made famous by Sir Jimmy Shand. 3 rows tuned B, C , C# .These are easlily chromatic and a mere 5 scales provided the wherewithal for 12 keys. All notes with the exeption of G, D and A are available in either bellows direction and anything up to 120 bass. and 4 treable voices. The bass being obviously not effected by bellows direction.
The famous Shand MOrino box ( designed by Jimmy Shand and ?Venesio Morino came in two sizes 105 or 117 Bass!
The so called diatonic ( even though many are actually chromatic) boxes are fascinating to play and well suited to many types of folk/trad music but are not suitable for 'classical' stuff because of lack of availability of some right hand chords because you simply can't come and go at the same time! eg a full G maj chord is impossible on the treble but then few listeners would notice the lack thereof
The book A to Z of the Accordion volume 4 ( by ROB HOward) contains a 5 page article by me on diatonics ( one mans diatonic musings) The whole series of books makle a very good read and are, I think still available
