Alright then thanks for you help David

Yes it works perfectly, so I'm under the assumption that there is something wrong with the project itself?

In the screenshot it doesn't, but that was only after I had moved it back to 0 1 1 1 purely to see if that made any difference to the drum replacement.

Ahh my apologies it appears you have to open the screenshot in a new tab to view the whole image, but yes it does begin at 1 1 1 1.

As you can see the MIDI data occurs well after the transients attack. • Logic version: Logic 10.0.7 • OS X version: OS 10.9.5 • Computer: iMac • Processor: 2.7 GHz Intel Core i5 • Memory: 8GB • Audio interface manufacturer and model: Komplete Audio 6, Native Instruments • MIDI Controller manufacturer and model: Novation Impulse 49 (when connected, but is currently not)

Whenever I try to use the drum replacement in Logic X it always puts the MIDI data about 1/2 a second too late even when I make adjustments. This means I have to manually adjust the timing of the MIDI track to be level with the audio recording. I'm not sure if this is a bug for my Logic or not because I've seen it work perfectly on other Logic users work.
