Sorted mine , turned the bufffer up full blast and ticked hardware buffer in audio properties

cpu rate sits nicley on about 20 now !

And also ,

Once you have scored what ya want with a plug in & automation etc.....

Export that pattern as wav , the delete plug in pattern , then insert wav !!!

Jon told me that , and it works , free up the cpu by playing a wav , instead of all the above !

Obviousley cant ammend , but if you feel your gonna ammend save plug work as midi etc......
