Default Latency?

I'm running Reaper on a Windows PC with an Intel i5 procesor running at 3.2MHz and with 8Gb of RAM. I have a FocusRite Scarlett 2i2 Studio and my midi keyboard is a M-Audio Oxygen 49.

There is slight delay between hitting a key on the keyboard and the VSTi synth, or whatever, producing the sound. I looked this up in the keyboard manual and it described the problem as "latency" and offered the following solution.

"If you already have an adequate sound card, try re-installing the latest drivers for the
sound card, or try reducing the buffer sizes of the audio drivers."

Please could someone tell me how I can do this?

- Go to Options > Preferences > Audio > Device.
- Set the audio system to ASIO.
- Set the ASIO driver to your device.
- Click the ASIO configuration button to bring up a window for changing settings for your audio device, and find the buffer setting. 256 samples is usually an ok middle of the road starting point for the buffer setting. The panel may show the buffer setting in milliseconds (ms) instead of samples. If that is the case, you might start with something like 10 ms. Either way, the lower this setting is, the lower the latency but the higher chance for clicks and droputs due to the computer not being optimized for low latency audio performance.

Default Many Thanks

Thank you very much, Brainwreck. It seems perfect now.

I now remember that when I started with Cubase LE in 2007 I had a similar problem which was solved in exactly the same way! Oh well, I was 63 ten days ago so maybe my memory is allowed to be imperfect on occassion! :-)

Thanks, again.

I agree 256 is a good starting point. Organs are completely fine and pianos are playable, albeit not perfect.

I find 256 is the best place to set it for overall work. Allows mixing a full session without glitches on my system and also allows reasonable real-time playing of keyboards.

For horns, I need to bring it down to 32.

I think he more attacky a sound is, the more it will suffer from latency.

Apparently playing a pipe organ in a large church comes with quite a big natural latency but the organists just learn to play like that. Possibly why organ VSTs are more playable at higher latency.

Of course, a percussive hammond part might need lower latency as much as a piano etc.
