Or be able to shift the time between transient markers?
i think you need the ableton forum
the only thing thats keeping me like 
something that ZeroFly explain to me a while back …i dont understand too much the technical aspect of it
but basically it was that renoise its unable to spread the cpu load acroos the cores
when youre using meta devices controlling parameters in other tracks
in my case …
my sidechain / ducking setup
that’s some serious optimization problem or whatever you want to call to it …
i mean its not the end of the world since there are people far more talented than me making …truly amazing music with Renoise but yeah
it kinda bugs me 
We need Renoise v10,000.9 I guess… Oh well
