...The Eb instrument is still impossible except for your C# 12.3 layout - which incidentally is the only layout (I think) possible on the original Pro Solist 12. Jim Hanks
I posted a guide that shows note layouts for 10 different fourkey harmonicas that are feasible in the Configurator for Seydel's Soloist Pro 12 Steel; see http://home.comcast.net/~rbmy/fourkey12s.pdf For each of the feasible layouts, I show the notes in rows like the Configurator entry form, so it should not be hard to copy them into the Configurator. -Roger
