Yes WAS is very old tech , in the 1990s as I remember. Latency is the issue for audio interfaces, something less than 6m sec, or you can feel a lag when playing. I will be in touch but have some rehearsals first. ASIO was invented by Cubase to minimise latency which is the round trip time between striking a note or message in MIDIand it coming out of the speakers, to much delay makes playing silly. Makes no difference to playback only.
My money is now on a setting in my older song files, breaking the count in functions. Thank you for the support people.
