re saveing preferences.
in any daw its the same ...youll normally see a preferences screen
for driver selection, and a button called ok and/or apply.
for example in realband ensure after selecting audio and midi drivers
for the delta that you cliok OK button.
youll notice in rb when you clik the drivers button and select drivers its important
to move selected devices to top. this is what i have to do in powertraks.

for some new folks the delta control panel has confused from posts ive seen.
so one also has to ensure that the delta control panel is set up properly.
then on the trak itself, in rb prolly you have to ensure the right port is selected.
rharv knows more than i bout the delta as he has one.
also to echo what he said...in windows itself it might be prudent to select
the delta as the default sound device on your puter.
this way on board sound will be negated.
its all a learning curve like anything.
but if you get super frustrated, as i said mebe try a very simple sound device.
for example one simple device i have here for audio is edirol ua1ex.
now updated by the ua1g i spoke about.
before buying the rme for example really look at the manual and understand
all thats needed to install n set up the device.
the manual for any device will allow you to assess how simple or complex it is.
before buying. in summary before buying any new device get a gander
at the manual to assess if its too complex for you.
finally , sometimes one has to try various deviceds to see which one
works best on a puter. yes its a hassle..but thats life..lol.
all the best.

retired puter engr....powertracks on amd......NICE !
