In RB2022 64bit I've noticed that,in Staff Roll Notation Mode, the appropriate symbol is not displayed beside the note when that note is Sharp, Flat or Natural relative to the Key of the song.
The symbols are displaying in Standard Notation Mode and Editable Notation Mode. The symbols display in all three modes in RB2019 32bit.
Am I overlooking a setting somewhere or is this an error?

Can you post a screen shot of the 2019 Piano Roll when it DID display?
I'm not challenging your observation, I simply do not remember seeing them previously, and am curious to see how they displayed; maybe I was simply not seeing them.
Curious is all.

As far as I know they have never displayed on the Piano Roll.
I am referring to the Staff Roll Notation Mode.

In The Notation Window for a MIDI track, from top left you have;
Options Button, Print Button then the three display option buttons;
1. Standard Notation Mode
2. Editable Notation Mode
3. Staff Roll Notation Mode
All three options display Sharp, Flat and Natural symbols to left of the note in RB2019 & RB2020 32bit but only options 1 and 2 display these symbols in RB2022 64 bit.

I see it now, thanks
Being able to get a screen shot will likely help
