Nice look, build and the sound quality but was very dissapointed that the volume at the rear inputs is incredibily low. I have tried plugging in my drum machine in to th rear inputs and keyboard and the volume is unacceptable. This was a response from Focusrite: “ You do highlight a familiar point with the inflexibility of the line inputs; this is something that we are looking to potentially include in future products should this be feasible. Since these fixed gain ports are designed to accommodate such a wide range of input levels (including very 'hot' signals), when some third-party hardware such as drum machines (which are not outputting at such a high level) are being used they can be a little quieter than ideal.” From what I read in the forums a lot of keyboard players are unhappy after purchasing this interface. This interface is more suitable for recording vocals and guitars but not drum machines or keyboards. Also it is not a very straightforward way to set things in Focusrite Control. Was quite dissatisfied and didn’t expect this from Focusrite. My honest review.
