There are no plans to support bit bridging in Studio One,
We suggest anyone interested in this should inquire with plug-in developers for 64-bit versions.
We've had varying reports of success with JBridge, SoundRadix and BridgeWize, there may be others. We have not tested nor do we recommend any solutions. If you use one of these and have questions, use the community forum or social media to get assistance from other users who may be able help.
