Please consider adding more ports for ADAT and SPDIF inputs on future Quantum models, with Sample Rate Conversion (SRC) if possible.
I have a lot of synthesizers with digital outputs (some older, some newer), a few dedicated ADCs that I like using, and some preamps with digital outputs. There aren't really any digital mixers on the market that can accomodate so many digital inputs. I'd love if I didn't have to chain together a bunch of Quantums to accomplish this.
