I have recently bought a low-end usb keyboard(Acorn Instruments Masterkey 49). I am trying to use it with Sibelius 6. After spending a lot of time in the settings of Sibelius, I have managed to get latency down to 10ms, although I am not happy with that. I am using a laptop so I'm thinking this must be the limit for my current hardware.(CPU/GPU are good but I'm guessing sound is rather basic) I was told that this latency is probably due to my sound card.
After a lot of googling I couldnt find any external soundcards that seem to work for me. Can anyone suggest some that I should look at? Keep in mind the keyboard I am using only has USB connection. Thanks !
p.s I am a uni student, and using the above equipment for my studies, so professional equipment is out of budget.
Win 7 64bit i7 3610QM 2.3Ghz 6GB RAM Realtek High Definition Audio(WASAPI)
Sibelius supports ASIO drivers although the system doesn't(option is visible in settings, but greyed-out).
