The Pan / Erase button light is enabled when you enter the step sequencer and it doesnt turn off until you fiddle a bit.
Steps to reproduce:
Press step program
Press F2 to enter TR Mode
notice the pan/erase button turns on right away
Hit F2 again to exit TR mode and the Pan/Erase button is still illuminated
Exit Step Program mode and Pan/Erase is still illuminated. you have to push it 2x more to turn it off.
If you leave step program mode while TR is still on and make erase disappear, when you re-enter step mode, the erase button comes right back on with f2.
Steps to fix:
Pan/Erase light shouldn’t be turned on by entering TR mode.
