just to comment on some items in your post..

Catalyst does Play back Audio files ... Catalyst also can lock to Midi and Time code...Its very flexible.

Catalyst is in daily on literally hundreds of productions - each is totally unique in configeration and execution..... The forum is read by Catalyst Techs and resellers from around the world but.... you need to be able to discribe your requirment better so that posters can better help you...
