[One Winged Angel]

If you're playing strictly as86 for some songs and asdf for others, yeah that's obviously perfectly fine. I was kinda confused by what you meant in your post, I thought you were suggesting for Halogen to play as86 for the majority of the song but then switch to a28f for the [14]...2323[14]... jumpjack section, with the left hand on af and the right hand on 28.

edit: 'So if you can manage the transition between the areas...'

lol nvm, that's definitely DS :/

You have to stick with the same four keys for the entire song
