Hello, I purchased the whole SR bundle. The problem is that all the SR plugins are producing a lot of latency in the channel that are added. I don’t have this problem with any other plugin. I’m on Protools 2018.04 on MacOS 10.13.5 Thanks Alex ---

Hey Alex! Sound Radix plug-ins benefits from digital world advantages. “knowing” the future (by adding latency) is part of it. I’ll do my best to explain each product in that regard: - POWAIR, uses latency as superior lookahead for compression and leveling. - Drum Leveler, uses latency for best possible detection. - Auto-Align, provides latency to allow adjusting things also back in-time. - Pi - uses latency lookahead to optimize **all** tracks. - SurferEQ - uses latency for accurate pitch-detection. btw, SurferEQ has `LIVE` mode that allows you to get it to run in lower latency. Sound Radix plug-ins would work best on systems with proper delay compensation. As you’re using Pro Tools, make sure Delay Compensation is turned on - ![image](https://canada1.discourse-cdn.com/flex003/uploads/soundradix1/original/1X/1bb1cf3216f084511b016abede8c1e4390743c1f.jpg) If you need farther assistance or anything our [support is click away.](https://www.soundradix.com/support/)
