Focusrite's Scarlett series of audio interfaces is a go-to for recording engineers at every level for their promise of ultra low-latency and endless flexibility. The 2i4 model is a great option for home recordists on a budget, providing two combination inputs with natural-sounding preamps, as well as MIDI ins and outs, which also make this Scarlett ideal for any musicians performing with live outboard synths. For studio use, it also features 1/4-inch balanced jacks for connecting to studio monitors or four RCA outputs for connecting to a home speaker system or DJ mixer.
