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......
