Cannot change track in piano roll

Hi, folks.
Win 10. n-T 10.
I can’t change track with the button in the upper right of the piano roll.
Just me?

My mistake - but - is it no longer possible to open the piano roll for a drum track.


that’s strange. What happens if you double click on the track’s waveform? Does the pianoroll open on other tracks? The pianoroll should always open on all instrument tracks except for step sequencer ones.


Hi Flavio.
Please ignore me. I opened an old project in n-T10 and at first it seemed as though there was an issue. I cannot recreate the problem and all is good.
PS. Loving all the new features in V10.
