Tempo sync issues with Logic

[gmaahs]

Hello, I have a project with a slight temp change in the bridge that goes up a little bit and then returns when the bridge is over. I have drawn the tempo change to my liking in Logic, exported it in a midi file, and imported the tempo into SD3 using the “import tempo from midi file” selection in the track tab. Follow Host is selected.

When I record the guitar part, everything synergizes fine, and I record the part in sync with the drums. However when I playback, the drums are out of sync, and from what I can tell, the drums are behind the guitar, telling me (I think) that the drums are not following the midi tempo file during playback. Although I am not entirely sure about this.

This could be a Logic problem too, but I am starting here because the tempo in Logic is consistent every time, and it seems to me that it is the drums that are out of whack. Anyone know what is going on here?

Thanks in advance,

Gord

How did you draw the tempo in Logic? Anything with curves or smooth diagonals are not finely interpolated outside of Logic. That’s not a bug.

The tempo in Logic is a gradual line. When I imported the midi into SD3 I noticed what you said, because rather than a gradual line SD3 interpreted that as a series of small gradual changes instead of a smooth line. But I’m ok with that, it’s not a deal breaker lol. Rather, the thing I don’t understand is that when I record over the tempo change everything is in sync, and then when I playback the part I just recorded, it’s then out of sync. When I check the bpm in SD3, it even follows the tempo change, same as Logic.

Why would the playback be out of sync, when it was totally in sync when I recorded it?

For me, I never import a tempo into SD3 as the plugin should follow the tempo as laid out in Logic when you have “Follow Host” enabled on the transport bar of SD3.  The only time I import a tempo into SD3 is when I am sharing my project with someone else who is using the standalone Superior Drummer 3 application.

Why did you decided to import the tempo in the first place?

Regardless of the tempo that was recorded, you don’t need to import the tempo into SD3. MIDI translates to any tempo. The drums won’t sound any different.

The main reason everything is going out of sync is because of the non-interpolated tempo in SD3. Delete it from your tempo track and ensure Follow Host is on. Let Logic dictate the tempo.

Hi Everyone, thanks for the help

Red Gear: The reason I decided to try and import the tempo is because initially, with follow host clicked and the tempo change only drawn out in logic, the two parts were going out of sync, but only after I recorded it. During recording everything synced together fine. I could hear the tempo change as I recorded the guitar, then when I would listen to the performance, the two parts were out of sync. In trying to solve the problem, I thought that if I imported the tempo to SD3 it would sync together. I’m at the beginning of this song and I only have two parts to contend with so far, a scratch guitar part to build the drums to, and the drum part itself, which I haven’t really started working on because of the sync issue.

Bear-Faced Cow: I think the above statement speaks to your comment as well, as I initially didn’t have any tempo markers in SD3 and expected follow host to do all the work for me. I tried deleting all the tempo markers as you said, and still the problem persists.

As a note, I am (perhaps obviously) not an expert in either program, and I expected SD3 to follow everything in logic. I only started down this rabbit trail because the two programs weren’t syncing the way I assumed they should.

I’m considering ditching the tempo change altogether if I can’t get this to work, though it’s too bad. This song is a fingerpicked electric guitar piece that will just have sparse drums in it as accents. When I played the piece normally I would naturally increase the tempo in the bridge, and I want to be able to mirror that in the recording, albeit with a much subtler tempo change than I tend to in real life. 😉

I really appreciate the suggestions as I’m at a total loss as to what to do.

What are the specs of your Apple computer?  I wonder if you enabled low latency mode when recording the track if that would help?  Do you have a lot of other tracks with plugins/fx going while recording?

There’s only 2 tracks so far with this song lol, It should be alright, considering how many I have in other songs that seem ok.

This issue has been solved. I simultaneously posted on this site and. Logic aside as well.

I guess Flex was turned on, so it was doing something to it after recording. As soon as I turned it off everything worked.

I knew I was a tighter guitar player than what I was hearing 😉

Thanks again everyone
