Hi Tony,

It's not clear exactly what you want to do. Do you mean you want to use the same relative key positions as a major scale, but to play a minor scale? If so, you need to change a major scale layout tablature set to minor.

You can find the Hohner Corona 3 row layouts at melodeon.net.

Look at one of the major key layouts, such as G/C/F (set up to play easily in the key of C major. You could change each major scale note to a corresponding minor scale.

For example, to make Am scale, change all Cs to As, Ds to Bs, Es to Cs, etc.

You could do the same with the notes on your organetto, which may or may not match the Hohner 3 row. You may only need to program the keys on your organetto, not all 3 rows.

I have not seen such a layout on the internet but it wouldn't be hard to do. Then it looks like you have to download a tablature making software to make the sets. Or find some from someone. I don't have this instrument so I don't know if you can make bass notes and chords in all minor keys.

Or, you could do like the TexMex guys and play in minor "cross keys," ie, Am on a C layout.

Maybe someone with this instrument can explain it better. Btw, what minor key do you want to play in?

Hope this makes sense

Hi yes i wanted to chance from major scale to minor
I can do that with this roland accordion in conjunction with the software, I've tried do it on my own but i made a mess ,so i wanted a layout or blueprint in front of me so that i an just copy
Key is not important because i can just transpose, check YouTube
For the feature of this accordion so that will make sense to you

You could say diatonic boxes are designed to play minor tunes 'on the pull.'
Looking at the layout - Say 3 rows in GCF:
ON G row - hold down gbd buttons and pull = Aminor chord
On C row...……………….gce……………………… = B minor chord
On F row...……………….cfa ……………………… = G minor chord.
For Aminor scale: start on noteG of G row - pull then C row, then G row - all on pull. For note b go to F row or change to push on G row
On a GCF the basses are designed for playing in Aminor - on your box that's obviously not a problem - just transpose as you say.
You will run out of air - avoid this by using push where that is an option.
If you look at a GCF layout chart you will see you can even play an A minor scale entirely on the push - start on the a push on the F row.
Hope that helps.

Tony, I am sorry I cannot help you..I am strictly an acoustic player BCC# 117 bass player. I do not understand the vagaries of 2 row boxes except the B/C boxes with with stradella bass.

Or electronic boxes either
