Andrei,
Thanks for the reply.
After using Orange CD for several years, I think the "custom data base" for "roles" would suit be best.
The delete button works OK especially now that "autofill" is always on. However, sometimes I forget to delete and then end up going back through all my entries that have bass clarinet or the others, like drums/percussion and fixing them from memory or digging out the liner notes.
Like I said before, not a big deal
