Logic 9 Recording Delay

    I just went in to Logic Pro 9 and changed the manual adjustment for the "Recording Delay" like a retard and I didn't look at what it was before I touched it. Is there a way to reset it to what it was before I made the adjustment? If not how can I set it to be correct?

    It's default is 0. Change it to 0 and you should be ok.

    This doesn't quite make sense. Having some issues myself. The obvious question is what is the recording delay parameter for if you should set it to zero? The other observation is a lot of people say they do a out and back in recording test and they set the recording delay by the round trip. I've been doing some recording and having some wacky timing issues, one beting an internally generated sequence (exs drum pencilled in) was quite late in respect to several recorded acoustic instruments (usually it is the other way around).

    The record Delay is to adjust the latency of your sound card.

    For the Loopback test:
    -Create a complete new session
    -Insert the I/O plugin to a mono audio track
    -Mute your audio channel and speakers
    -Patch a physical cable out of your interface back in. Let's say output 1 to input 1.
    -In the plugin, select your output and Input and press Ping
    -The Latency Offset will tell you by how much you should adjust your recording Delay.
    Let's say you get +22, you will then adjust your recording delay by -22
    -Don't forget to do the test again when if you change sample rate

    If you have an RME card, your latency could be 0.

    Is the "round trip" display in logic just a calculated guess? Another question i have is about buffers. My understanding of a buffer is you suck in extra data at the outset but the delay should be in the start of recording (not referring to ad conversion delays. If the conversion and cacheing to ram/disk cant keep up is software "fixing"that sort of like happens for cdda playback?

    No it is precise. It subtracts the buffer which is the software latency and leaves you with the interface latency result only.

    I'm not sure I understand your question, but yes, the software will compensate for the software's latency when you record, but it can't compensate for your interface's latency. That's why out need to do the loopback test.

    You would probably like the Logic 9 207 course from MacProVideo.com

    Addressing this again because of experiencing some latency issues (or perceiving them). Since the round trip latency calculates it via what ever hardware you have hooked up why wouldn't it compensate for both when recording? You are saying it only compensates for software delays? (Logic Pro X itself then). I did a round trip analysis and got about 2 milliseconds offset. The round trip latency showing in the logic preferences is something like 13 ms. So I guess logic is adjusting 13 milliseconds an that means the hardware is still introducing 2 ms?

    That would be right. 2ms.

    Logic can't compensate automatically for the sound card. Each sound card is different. The fact that you plug a cable form the out of your sound card to its In is the only reason why the plugin can calculate that latency. But you have to write it manually after.

    Now don't forget the Plugin Latency also. That's something else. In Preferences, Audio - General, your Plugin Latency Compensation should be set to Audio & Software Instruments. But if you add plugins to the master or Aux tracks, then you need to set it to ALL.
