Since installing auto-tune pro, I have noticed that on songs using the plugin, I am getting dropouts every so often... Its completely unpredictable when it will occur, it could happen anywhere between a couple minutes to 20 or more minutes... It seems to get worse when there are multiple instances of the plugin in the session but has occurred with just 1 or 2 instances also... I had no trouble with auto-tune 8 or any version before that... My CPU is usually showing very low usage and everything seems to be working fine... then for a quick little moment all audio drops out and then recovers like nothing happened. Not a big deal if i'm just mixing, but I also use auto-tune while tracking (like very very often)… When the dropout strikes during recording, there is a little dead space committed to the incoming audio file.
I normally use Low Latency mode in auto-tune pro, or classic mode. I run auto-tune in automatic mode, then use melodyne to fix up any weird stuff after tracking.
I first thought the issue was due to an underpowered pc (which was an older i7 with 8gb of ram), and i have since upgraded my pc to the fastest i7 currently available (not running any overclocking or throttling. I have even disabled hyperthreading to try smooth out this issue)
I just downloaded reaper to do some testing... I loaded up auto-tune pro on 8 audio tracks and played around with it in reaper for a while and didn't find any issue there... perhaps if I really work a project in reaper I will find some problem but after half an hr trying to learn a few basics of using reaper I was running back to my comfort zone in studio one!
I have tried to fix the issue by changing the dropout protection levels in SO4, running with the green z active and disabled... higher and lower buffers on my fireface uc… and at some point the dropouts have always come back.
I contacted antares support and they say no one else has reported any problems with Studio One and Auto-Tune Pro. They had me uninstall and reinstall the plugin, and also update my ilok driver... Still no fix. I also updated my rme drivers to cover all bases. I wondered how this is an unknown issue to Antares support, but after searching this forum I see that no one has even mentioned Auto-Tune Pro here at all! A bit strange since Auto-Tune Pro is also one of the few ARA plugins available (for graph mode when inserted as clip fx)… I have one friend who is still on studio one v3, and he told me that he has also noticed a few dropouts per hr on his system since moving to auto-tune pro.
These dropouts never happen in any session that does not have Auto-Tune Pro. As a work around, i have been using my old Auto-tune 5 thru Jbridge on all my recent projects while I hope for this to get worked out. Auto-Tune 5 is very smooth as far as audio performance.. Just very slow to load and copy due to the bridging.. I really want to get Pro working as expected.
Any other Studio One users are having a similar experience with Auto-Tune Pro?
windows 10
i7 8086k processor
16gb ram
rme fireface uc
studio one 4.1.1

I also have noticed some heavy cpu from Auto Tune Pro, I've found it also spikes in Cubase 10. This seems like an Antares issue.

I stopped using all Antares because it doesn't seem to be optimized anymore. It acts the same way in all DAWs I've used. For AutoTune, I now use Waves Real Time Tune. Works just as well, and has no spike.

I quit using AutoTune and its stupid USB dongle protection. I should have known better. I will never buy another product that requires a USB dongle. AutoTune created many issues (more than I want to go into here) but, as soon as i removed it out of system everything started working properly again. Maybe just me as I am sure lots of folks find it works for them. Big waste of money as far as I am concerned.
I did buy the UAD plugin and have had no issues so far (no dongle required)
