Hi,
I wrote a report here, too: https://www.kvraudio.com/forum/viewtopic.php?p=8024841#p8024841
Synthmaster One 1.42 macos does not seem to be automatable, it starts to heavily crackle then. I guess it is a problem on Synthmaster’s side, but I am posting this here just in case.
On the other hand, since such a big flaw would be already reported, it might be a problem in Renoise then.
Example song:
bug-synthmaster-one-automation.xrns (11.2 KB)
That example produces heavily crackling here. Once the automation device is deactivated, the problem disappears.
Thanks.
