Crashes

I bought a SynthStation 25 with plans to use it with this app. First I would get long stuck notes. Then increasing crashes till finally it crashed every time at start up. At first I didnt mind because with the purchase of Midi Bridge $8.99 I could use the SS25 with better apps like NanoStudio and Alchemy but then that connection started dropping out and then reappearing again about every 4 minutes.
The fact that the SS25 doesnt come with a wall jack or a USB cable or even the $2 SynthStation App makes me wonder what Is going on with Akai.
I returned the SS25 and deleted the App.
