So I ended up purchasing the SX, and even with the limited capability of the soundcard for my original application plans, I have found it to be a right fun little piece of kit.
I have very few issues with the hardware overall. I think it's put together very nicely. However.......for me, the resonance on the dedicated HP/LP filter knob is just a bit too bright for me. Is there any way to reduce the resonance on the filter? If not, might i suggest a firmware upgrade that would allow this adjustment?
My vote would be for [shift]+filter knob adjustment = allows for increasing or lowering resonance amount.
