Hi
Yes i have done this.
2 sets of delays with the 2 matrix’s
I used a ipad QuPad with a custom layer …
Or you could use custom layer just on the surface?
I sent the FOH post everything to matrix’s.
Or you can send a mix to Matrix.
But you cannot send a channel direct to matrix.
Go to your upper layer
select matrix and then Routing tab and then-function key to access the amounts of mixs
Hope this helps
If you get stuck I’ll send you a PM tomorow.
