Thanks for the answer.
My first question was moved by the existence on Thumbjam of equally tempered scales as nonatonic decatonic and so on. So I asked to put on the list even my eight steps and if possible the sisteen steps too.
Particularly this last is used by some Italian musicians wich call it Armodue, and by an American guitar builder. The eight tone one, is implemented by Leisuresonic in his Cosmovox and Synthronica apps too.
Regarding the second question, I think it would be useful for users to know which other apps are verified compatible with Thumbjam on midi data transmit / receive, by mean respectively of usb bluetooth or wifi, to spare the time of unuseful experiments. Same for osc.
