Hey!
I use a french azerty keyboard and I noticed in the SFX editor that the keyboard key for G# (6) is the same as the hotkey to go back to previous SFX screen (minus).
This means if I want to play G# in SFX 01, pico-8 plays it and then comes back to SFX 00, and I have to go back to SFX 01 to continue playing.
Thanks a lot!
