Can you upload an example (xrns ) ?
I never had any issues with washy transients , but I also almost never change the bpm/lpb in a song
I am aware that the both filter and pitch modulation amount varies when adding a second curve in the envelope because of the interpolation time
See here
There are enough examples of tunes made with samples only and they all sound pretty damn good .
Don’t get me wrong , I can also get pretty anal about stuff not working as it supposed to be , but washy/dull transients is not one of them .
Let’s give us a real life example
