Recording Latency

Okay - even though I've been recording for a long time, I'm about to ask a really newbie question.

I'm recording the audio from a drum machine through a Focusrite Scarlett 6i6. The drum machine's clock is being controlled by Ableton's via midi. My latency is only about 5 ms - buffer size is 88 and samples are 64. When I look back at the audio file, the transients don't line up on the grid - they are just a little delayed. Theoretically they should because of the clock. Is this just an unavoidable consequence of the routing, or is this latency that I can address and resolve?

Couple of things...

Do you have the recording track's monitor set to ON or AUTO? This will always introduce a certain delay or offset in the recorded material. The trick is to leave monitoring set to OFF and monitor the incoming audio directly through your audio interface via zero-latency or direct monitoring (i.e. Direct input monitoring before A/D conversion using the Focusrite Control panel.)

Once you're doing that, and if you're still getting delayed recordings, try adjusting the MIDI clock sync delay to a negative value in Live's Preferences > MIDI > Output until your beats line up exactly with the grid.

I'm going to try these tonight. Thank you - great suggestions!
