Thank you for the feedback Huy, it sounds like you may have more than one instance of BBM4 running in the background. BBM4 is the BIAB engine that the plugin uses to perform most tasks. The way to fix this is to open an app in Applications/Utilities/ called "Activity Monitor". Then find the process called "BBM4" and double click it to open a window with an option to quit. Make sure to do this when the plugin and DAW are not running. If after following these steps, you open an instance of the plugin and it continues to spin endlessly, you could also try to click on the 'File' button on the top left of the plugin and select 'New'. This should close any running instances of the BIAB engine if the spinning wheel is stuck. Let me know if you are still having issues.

Hi TDay, it seems like your issue is quite different from what Huy described and therefore it would be better if you created a new forum topic describing in detail what you are experiencing. This way we can respond to your issue directly without having to answer multiple unrelated questions. Can you provide the exact steps to reproduce the issue you are experiencing? Style changes do not currently work in the plugin but we are working on fixing this for the future. If you are able to load the plugin and open the style picker than it sounds like the plugin is responding as expected. Are you able to load a style and generate tracks? Please create a new forum topic for your response with a title that accurately describes your reported issue. Thank you for your feedback!
