Customer says: Just a quick note to say how pleased I am with the summing mixer.
I’ve summed a piano session and a jazz session and all I can say is that it makes things sound finalised or complete! Its hard to put my finger on it. It’s like a sonic glue! There is definitely a stability that it adds. Sounds like a record!
