Hi ,

I recently bought a Focusrite Scarlett 2i4 . I have connected my Midi Keyboard ( Korg X50 ) to the Audio Interface through a Midi Cable . I find that there is so much of latency when I do that . Does anyone know why that occurs and how to solve the problem ?

Please find the specifications of my computer below :

Intel i7 3rd gen processor
8 GB RAM
1 TB hard drive
Windows 8 64 bit
DAW used : Cubase 5.1 32 bit

I'm dealing with the exact same issue!!

I use Ableton Live and an Electribe to make my sounds.

I use the electribe to sequence, and I use Ableton to record audio, record midi sequences, trigger midi tracks, etc.

However, I've just started doing all this, and have noticed that there's a pretty significant latency (a bit more than a 1/16 note) when I record in either audio or midi on Ableton from the Electribe!!

What to do? I know that the Electribe is spot on with the timing--if I direct monitor the inputs, they're perfect, but the signal, after going into the computer, is off!

I'm so close to returning this interface if I don't find an answer soon!!

Thanks for helping a noobie!!!

I emailed the Focusrite Technical support and they are really poor in indentifying the problem :(

Ok .. Let me check my connection again :

I have connected my midi in from the midi keyboard to midi out in the interface
and midi out from the midi keyboard to midi in in the interface

Are the above connections correct ?

Are you sure it is midi latency and not your audio settings causing a latency in the sound being generated. Go into the settings and check on your audio buffer setting- should be around 128 (and down to 64 if your system can handle it). Sounds like you are at 512.

I have it in the format of milliseconds .. how much should it be ?
Please3 find the settings in the below image :

You have 31.2 ms roundtrip latency; that's a lot. And yeah- including processing time, your buffers are probably at 512 samples; 512 samples equals 11.6 ms each way. You should be able to cut that in half if not more.

So how do I reduce that ?
Should I reduce the milliseconds ?

Well Steve, you can open your audio card's control panel, reduce buffer size. That'll do er! Consult manual for options regarding tasties.

Won't it deter the quality of output ?

What? Buffer size affects latency.

Will reducing the buffer size reduce the quality of output ?
For example , if I have a grand piano midi track , if I reduce the buffer size , will the quality of grand piano go down ? Wouldn't it be as clear as having high buffer value ?

Buffer size has nothing to do with the audio quality of the samples being used, but rather the amount of memory that is used as a 'holding tank' of sorts while audio is being processed. You should generally make the buffer size as small as possible, without 'crackling' and/or dropouts in the playback.

With as much power as you have with your PC, you can probably get the latency down to just a few milliseconds by reducing the buffer size.
