Hi guys,
I recently have calibrated bellows sensor on my Roland fr3xb and the bellows now are perfectly balanced but after reasembling the accordion right hand setup is completely off. The notes are all over the place without any specific order. Left hand is as it was. I tried switching between B and C griff and did factory reset but nothing helped. Did anyone have this issue?
 
Sounds like you've re-calibrated by hand by turning the internal pot? Sorry, no idea about FR3x specifically.
If that's the case, check all the cable connections, especially the ones coming off the keyboard. Roland are not exactly known for high quality assembly - something might have popped out of place.
 
Hello,
When pressed, do all keys activate a note even uncorrect ?
I could imagine that you switched your right keyboard from Button to Piano setting (first step in the test sequence ...) ?
 
All buttons make sounds and the layout is kind of like this: the first row when I play the buttons from the top, plays chromatic scale and the second row continues it but from down to the top. Then on the other 3 rows this chromatic order is kind of kept but not exactly (with some notes out of the scale). I hope it makes sense.

When I was calibrating the bellows I switched the test mode and then via register switch I accessed this view where you can see the numbers when pulling and squeezing the bellows. On closed bellows I turned VR1 trimmer with screwdriver to achieve intended number. Then I assembled the accordion and switched it off. After turning it on, the bellows reacted so much better but the right hand layout was off. Now when I think about it it kind of is like a piano accordion but with buttons.
 
Did you go to Calibration test (step 2 in test sequence) using Register [5] or Register [10] (step 1 in test sequence) ?
using register [5] (Clarinet) selects Piano type
using register [10] (Strings) selects Button type
I would advice to set again this setting ....
 
Thank you SergeRbt it works now after I switched it as you wrote. I thought now I will have to learn to play on the world weirdest button layout 😆. Anyways thanks again and all the best to you!
