Thanks for your replies, everyone.
My experience is regarding playing notes on my MIDI controller (a Yamaha S90XS). The latency isn't huge but it's enough to affect live playing, especially when playing/recording a drum part in realtime.
I tried pressing E but no change yet.
Driver mode is currently set to to WDM/KS. I recall having problems with ASIO settings in the past for some reason but I could try it again I guess.
The latency is currently set to Fast and the slider is all the way to the left (in the Preferences | Driver Settings window).
Should I adjust the buffer size? I'm not exactly sure what that does.
Or perhaps it's an issue with my controller?
Thanks,
CK
