Hi Michael,
Apologies for the delay in getting X2Pro to you. We just struggled for a short time with multicam clips. This was due to the fact that 10.0.3 does not export quite enough information in the XML to pin down the multicam and the user needs to export the appropriate event as well. We’ve got that nailed now and expect to submit the app to the store within the next few days.
The whole issue of mapping roles to tracks is interesting. What we do is to sort on roles and then pack the clips into as few tracks as possible, but with only one role on each track. I hope that will be most helpful to sound editors. It also allows for the possibility of only loading some roles into Pro Tools as you can select (in the Pro Tools import interface) which tracks to import and the role names are presented in the list.
