See my response in your other thread
You have a generic ASIO driver running .. not sure if you need it with the Delta, may want to try disabling it.

If you use your computer to connect to a Yamaha synth you may need it, but otherwise it may be interfering with the Delta drivers.
It's not a true ASIO driver from what I've read; more like an ASIO4All type driver ..
Make your sound your own!
