What usb audio interface to use

Hello guys,

Im new to producing music. I've bought a novation launchkey49 and i want to know what the best usb audio interface is to use when it comes to the delay when pressing a key. I'm using ableton live 9 lite. My budget is around €150. Right now i've seen a alesis io2 express wich seemed really good

Just about any usb interface in that price range will work. I really like the Focusrite 2i2 and the Presonus Audiobox. They have really great sound to be so small. Also, your latency will have a lot to do with your buffer size and the amount of ram installed on your system. For less latency, set the buffer as low as you can and increase as needed. Setting too low will cause a crackling sound. Setting too high will add latency when playing midi or recording audio. Most interfaces come with control panel software accessed in stand alone ore through your production software. Let us know what you choose...
