I bought this interface because I wanted a lot of analog ins and outs, and it delivers on that front and an amazing price. I have several synths and fx, and I like having my audio interface / PC as the central hub from which to route things; I find it preferable to a patch bay or manually rerouting cables.
Pro's:
-> Lots of ins, lots of outs
-> Construction feels solid
-> Sufficient amplification on the headphone out
-> Sufficient amplification on the main outs
-> Drivers on Win10 work well (64 sample latency on big projects without problems)
Cons:
-> No digital outs, so if you want to expand in that direction you'd need a different solution
-> The inputs are pretty sensitive - recording synthesizers I have the input knobs turned completely down, and get a clear signal with little noise. This isn't a con per-se, but if you, like me, were planning on using the input volume to mix a bit during jams, think again.
Overall I'm very happy with my purchase; the competing interfaces are either more expensive, or lack certain features this one has. If you're in the market for an interface with a lot of IO this is a solid choice.
