I already posted this in the bug reports but it miraculously hasnt appeared in that section.
When using warp markers to timestretch elastique algorithm produces crackles and artifacts that are also present in render audio. If i open the same edited files in 8.5.2 all is normal without any issues. TRied different elastique algorithms, different files always clicky.
This specially happens with sustained material like guitars or bass.
I really hope this wont take a whole year again (like it did with previous elastique issues in v7 era) because the warp stretching is useless at this point with 9.01
At this moment the only workaround is to use a previous version of Cubase if you want to use elastique .
You can use cubases native algorithms for the moment in v9 but I find them to produce more artifacts than elastique (with the exception of solo algorithm that is also used for variaudio)
It was said that this issue is planned to be fixed in the next (9.0.20) update,so lets hope it will be.
From what ive been able to collect the projects that were crackling here in 9.0.10 play normally now, so i guess its fixed. Ill try to do some more tests and report if I find anything faulty.
