I've got a pretty good piano-style keyboard that I'd love to use more, but the lag is killing me (the last two beats I've posted were done completely with the mouse - it's bearable, but nowhere near playing a set of nice keys). In FL Studio, when the device is set to ASIO4ALL, the reported latency of about 20 ms is actually much lower than what I actually get (I didn't try measuring it, but it's certainly a triple digit number). In the other mode (the regular one), it works fine at around 30 ms (just late enough so that my input isn't off beat), but after a few minutes the sound keeps glitching up (underruns start happening and they just don't stop until I slide the latency to something very high and return it to 30, which just repeats the same problem). I was told that an audio interface would "tame" the lag, but don't know which price range has the good ones. I don't want to spend over 60 USD because I also have some other stuff to buy before it. I'm currently using internal audio hardware from a 9 year old motherboard, which explains the latency. Basically, I'm looking for budget models and would like to know if it's worth spending less than $60 on an audio interface.
