I had formerly used a Presonus 1818VSL interface, and decided to upgrade, mostly due to the "lack" of Presonus support for the device (it would not allow the internal DSP/firmware to work with Universal Control, and had to use legacy driver package). However, I recently purchased a Studio 192 interface, but was disappointed to find that the Universal Control GUI (firmware in the 192) does not have any DSP processing (EQ/compression/limiter) available for the outputs 1/2, 3/4, 5/6, 7/8. It would be nice to have the EQ/compression/limiting available for the outputs like the 1818VSL did. My only option seems to be purchasing something like a ********* Ultracurve Pro DEQ2496 to compensate at this point.
