Korg microAUDIO 722

I upgraded to this audio interface from my Focusrite Scarlett 2i2. The amount of features beggars belief.

You get MIDI I/O, noise gate, compressor/limiter, and great zero-latency monitoring. You can route audio internally, and there is even a loopback function, so you can record your computer audio straight into your DAW, allowing you to sample YouTube videos, podcasts, etc. Then there is the filter. There are so much you can do with it: you can clean up heavily-distorted guitars, or cut out some of the harshness of heavily-processed audio. You can set the filter to an LFO just like on a synth. You can even switch the filter to use an envelope follower, having an analogue auto-wah right in front of you. You can also use the filter on everything, including your computer audio, and record the results.

All of the above can be used without a computer, including the DSP effects. You can use this audio interface on a pedal board, or just plug your synth into it (you DAW-less jammer degenerate you). It also comes with a VST plug-in, offering all the famous Korg filters if the integrated one isn't to your liking. You also get the usual Korg stuff, like Native Instruments bundle, Ableton Live Lite, and other things. Seriously, this is such a wonderful and versatile thing, I can't believe I lived without it!
