Hi Ben!

If you have audio hardware with ASIO drivers, I strongly recommend using these ASIO drivers. In Sibelius you can set the drivers of your audio hardware in Play/Playback Devices/Audio Engine Options.

Best,

Hi there,

I do not have ASIO drivers...

I am using M-Audio MobilePre USB which uses CoreAudio...

(However at the moment I am using the Mac's built in output because M-Audio haven't released a driver update for 10.5.6)

My keyboard, however, is connected directly via midi to USB (straight from the keyboard to the port on the Mac.)

Will it work better when I can use the MobilePre? If not what can you suggest?

Thanks,

Ben.

Which latency settings do you have set now?

Best regards,

Maya

24.35 ms.

with the MobilePre it goes up to 27.37 ms...

Hi,

I now have the MobilePre working again, but there is still a delay between when I press a note to when it actually sounds in Sibelius (which is annoying in fast passages because it sometimes skips out notes).

This not only happens when I press down a note, but also when the piece is played back...

Any ideas?

Thanks,

Ben.

Of how much delay are we talking here? 25 ms? 1 second?
Do you have this delay also with other virtual instruments?

Andi

It's less than a second, (but I'm not sure how long) Probably 25 ms.

It doesn't happen with the Sibelius Sounds :S

Ben.

Well if its around 25 ms, then its the latency of your soundcard. If you set a lower buffer size for your sound card, you will get lower latency, but it will take more CPU power.

Andi

Hey thanks! That seemed to do the trick :)

However, I don't really understand by "it will take up more CPU power"...

Thanks,

Ben.

This means, if you set the buffer size too low, you will get performance problems (crackling and stuttering playback).
