Arkos Tracker 2.0.0a2, Windows 10 64-bit
Steps to reproduce:
# Start a new song from scratch
# Set length for first pattern to 41 or 80 (doesn’t seem to matter as long as this value is over 40)
# Go to pattern editor, set step to 2
# Enter note or command data or whatever starting at pattern pos 0, just keep tapping the same key
# When the editor reaches pos $3E, instead of jumping to pos $40, it jumps to pos $3F (whereas expected behavior would be for it to jump to $40)
