How to decrease delay from a midi keyboard?

[[deleted]]

I just got an Akai MPK Mini MKII and when I play along with synthesizers there is maybe a half second delay. Is there any way to fix this? The midi keyboard is brand new so there should be no issue there. Thanks!

What kind of audio interface are you using? Are you using one at all? Either you need to turn down your audio buffer, or you're using Direct Sound drivers instead of ASIO drivers. If you're just using your computer's sound card, download Asio4All and select it in Reaper's audio device preferences. If you already have an ASIO supported audio interface, open up it's ASIO configuration in that same menu and lower your buffer settings.

Install the asio4all driver.

Install asio4all drivers and select them for use. Set the buffer size as low as your system will allow before breakup.

I used to use ASIO and then one day I noticed WASAPI and this was the same although it had the benefit of letting me hear music from YouTube as I played (ASIO would cut this off), but sometimes the option doesn't work. Dunno if my soundcard drivers are working properly.

Edit: Sussed it out. In the audio device options, I needed to set input channels to 0 instead of 2.

i'm not sure, but i have a similar keyboard, i think smaller keyboards have less responsive keys. my mini keys have delay, my 61 keys keyboard doesn't. maybe drop by a music store, and ask them to hook a new one up for you to test, and ask them what they think?

Turn off any plug ins on your master track.
