I recently picked up a vocal works TC unit and simple love it. With the help form folks here. Pat Marr was a huge help, among others, i was able to learn to use the thing very well.

i have been experimenting with gender and also a single shadowed voice at either a 3rd or 5th up does a very cool job,

The digitech unit also does midi input so you can have RB or PTPA , or even BiaB i imagine control it.
