Ok, yes when it freezes it will come back so that's not the big problem, please can you give me instructions on how to get the sound from the app to my keyboard, there's a configuration area but absolutely no instructions on how to configure. I just cannot work it out, I am tech savvy and usually very good at this sort of thing but I am beat on this one. I have both midi in and midi out highlighted and there are two keyboards one with 'thru' greyed or if depressed turns blue??!! When these apps are created it seems they are only for the experts :-) not for the likes of myself, it's a kind of guessing game, please guide me through the actual set up of the software, it appears it's not plug and play like the other apps are. I wondered if it's a simple case of buy the whole package and it will work. I am really grateful for your help.
