Had more time to experiment and the best I've so far managed using Phil's instructions
is a wavetable that ends at around 50% of the morph and that was using an export value
of 32bit. I am still not sure if the wavetable ditched half the table or not but it kind of looks that way.
16 bit wav export resulted in a table that didn't interpolate at all. It just stepped through the table as single cycles with no morphing.
I downloaded an EchoSound bank that was produced on Serum and that
seemed fine in ANA2 with full morphing.
I will of course continue to try and if I get a result will post my findings here just in case someone else has the issue.
Tekalight as much as I'd love to stay in the loop - I still prefer official forums for goto info, I refuse to join facebook
Anyway guys thanks for the help I am on the right track now.
