How are you using the existing delay as a track delay I’m interested ?
this was a request, not a suggestion of how to do it 
you can search on track delay on the forum for ideas on how to use the delay fx ,
but honestly, the delay fx is not designed for this, so its not really going to work very well for this.
this is a 4 year old thread, so Im going to close it…please don’t raise topics from the dead
