hey so I want to connect 2 midi keyboards via midi-usb into my laptop, but in order not to have latency I must use shitty ASIO4ALL driver. my question is if I buy an external audio inferface will it reduce the latency without reducing the sound quality [like the ASIO driver does]? if yes, where is it better to connect the keyboards: to the laptop's USB or to the audio interface's midi in/out?

thanks:]

Yes, external audio interfaces have a better sound quality and lower latency compared to average sound cards.

Whether you connect your controller via USB or MIDI doesn't matter very much. I'd go with USB, because 1) most external interfaces have only one MIDI in/out pair, 2) MIDI isn't bus-powered, so you'd need a separated power supply for your controller.

Ok. But if I go with one keyboard in the laptop's USB and one in the audio interface's midi in/out, would it be the same thing? I mean does the software recognize both of them [both with no latency]? [I'm asking because I've got only 2 USB ports xD]

Yes they'll both work the same.

Latency doesn't come from the keyboards to begin with -- both MIDI and USB signals reach the computer almost instantaneously. The lag comes from generating and buffering the sound after the note has been received. Latency is only due to the software and the soundcard.
