Why does my Studio One Crash on startup with 10.7 & 10.8 - "Hardware Integration Hang"

Studio One and Universal Control are very tightly integrated.  We provide this integration as a means for Universal Control to change sample rate in the program and the program to change UC's sample rate very easily.  With this, there is certain files that were created in 10.7 and 10.8 that Studio One needs to have installed properly or Studio One will load and crash after the beginning prompt says "Hardware Integration."

If this is happening to you, there are two things you need to make sure you have installed:

1.  Install the latest version of Universal Control from our website.

2.  Install the latest version of Studio One from the website.

Once you have done these two things above, Studio One (once started with the mixer properly connected) will see the mixer properly and the program will start up properly.  Here are the instructions below to do this:


1.  Make sure to manually remove any drivers prior before updating:

Manual Uninstall StudioLive - Mac

2.  Find your device's downloads page below and download and install the version of Universal Control for your Operating System:

FireStudio Project:

FireStudio Mobile:

StudioLive 16.4.2:

StudioLive 16.0.2:

StudioLive 24.4.2:
