Disabling ‘MIDI Retrospective Record’ seems to have fixed my problem too. Thanks a lot for posting this workaround. I recently started running out of RAM on sound design projects and couldn’t figure out where it was going. The only notable things that had changed in my setup was upgrading to Cubase 8 and switching to a Samsung SSD drive. It seemed more likely to be Cubase than the SSD (based on asking other people with the same SSD drive if they had RAM issues), and that assumption seems to be correct.
I mostly use Kontakt, other NI instruments (like FM8, Massive, Reaktor) and various UAD plugins. I’m running Cubase 32bit 8.0.30, Win 7 64bit and have 12 gigs of RAM. I’m happy to run some more tests if Steinberg is interested in investigating this issue.
As a general comment, I’ve generally been displeased with my Cubase 8 experience over the past 6 or so months. I upgraded simply to get the drag n drop feature from MediaBay to Kontakt, but as a trade-off I ran into the following issues:
- Poor video playback performance, such that I had to downgrade to rather old video card drivers.
- This RAM issue
- Overall heavier CPU usage
- A mixer that I find less efficient to use than the mixer in Cubase 5
- Broken side-chaining (e.g. with multiband compressors)
- VST bridge still not being sufficient to let me run the 64bit version of Cubase. I.e. I still use jbridge on occasion to get access to all my RAM, but I lose the drag and drop feature from MediaBay when doing so.
- Unanswered support tickets
- More crashes than I recall having with Cubase 5
Sorry for going off-topic, but I wanted to make sure my concerns were voiced somewhere that Steinberg might see them. I hope bug fixing hasn’t stopped on Cubase 8.
