Valhalla Room needs the flag “Auto suspend plugin when silent” disabled for it to work properly, otherwise one get’s weird cutoff decays like shown in this small video.
Yup, same goes for the Valhalla VintageVerb. Seems they’re suspended by silent (/no) input data, not output data.
Dunno about the Room, but VintageVerb anyway permanently adds very subtile noise (by intention), without processing any input. So it actually should be suspended by lacking output data, to keep the noise going.
While I don’t have any clue, if the suspending procedure is a renoise specific thing or probably a VST standard issue.
Yeah i got this problem sometimes, too.
