If Studio One Professional 5 does not show the Edit with VocALign command in its Audio menu after installing VocAlign Project 5, please update to at least Studio One version 5.4.
The Edit with VocALign command will appear in the Audio menu and VocALign Project 5 will respond to it.
If you are using an earlier version of Studio One Professional you can still use VocAlign Project 5 as an ARA plug-in: hold down the Option key on your computer keyboard and drag the VocAlign Project 5 VST plug-in from the Effects Browser onto the selected Audio Events you want to align - Guide and Dub(s).
This will add VocAlign Project 5 VST3 (ARA) plugin to the selected Audio Events, and open the VocAlign Project 5 interface in the Studio One Edit panel.

IMPORTANT NOTE: If you have VocAlign Ultra installed in you system as well as VocAlign Project 5, VocAlign Ultra will be selected as the "better" plug-in.
