I used the “Shaker Little” Sample the whole time with no success. Today I tried it again with the “Shaker Salt” Sample and now the Start Phase Parameter produces a very nice Swing.
Conclusion: Short Samples are not useful for this procedure.
Yes indeed, you need something quite long, hence why I chose a shaker sample with some hold, I suppose I should have indicated that there was a reason for it
Glad you worked it out though !
Cheers.
