Drum Designer out of sync in low latency mode? Help please.

Tony,

What is your normal setting for Plugin Delay Compensation? It should never be set to All until you're done with recording and into the mixing stage. It should be set to "Audio and Software Instrument Tracks"

Also, do you understand what Low Latency mode does? You are only going to use it for recording, it should not be enabled on playback. In fact, are you sure you need Low Latency mode, it's normally not used unless you're running latency inducing plugins (plugins that use look-ahead technology) like Pitch correction or the multipressor.

Interesting, I can't really address the situation as I'm still on L9, (can't experiment withLx until it's a bit more developed).

Do you have any latency inducing plugins on the master bus or the Drum Designer track? If so, try turning them off for the time being and see if it makes a difference. I understand in LX you can actually shut them off rather than disable. Does sound like a bug though...

But then there should be no reason to use Low Latency mode, in fact, Low LAtenct mode should not be used except under certain conditions.

What about bouncing the drum track to an audio file?

Just to confirm something..

1) Create brand new Project in LPX 10.0.3

2) Create Drummer track

3) Turn on Low Latency Mode

4) Press play and Drummer track should be out of sync with say, metronome or manually created click track using a EXS24 sample?

If so, it's not happening here...

Am I missing something?

Not immediately no but it doesn't take long for enough latency to build up to make recording problematic. Once a few instruments have been used - especially things like the Spectrasonics stuff - there's a noticable delay on midi and audio recordings without using the low latency mode

?? Instruments on their own should not cause a "build up" of latency, what audio interface are you using?

"Low Latency Mode checkbox and Limit slider: You need to select the Low Latency Mode checkbox in order to turn on Low Latency mode and use the Limit slider. The Limit slider lets you determine a maximum amount of allowable delay that can be caused by plug-ins when Low Latency mode is turned on (by clicking the Low Latency Mode button in the control bar). In Low Latency mode, plug-ins are bypassed to ensure that all delays (across the entire signal flow of the current track) remain under the Limit slider value. This is useful when you want to play a software instrument with several latency-inducing plug-ins inserted in the channel."

Tony, if you feel this is a bug report it to Apple using the provided "Provide Feedback" in Logic's menu. Since this is a user forum no one that can make a difference will hear about unless you do.

Tony,

It's not the Drummer but the Drum Designer with programmed midi part that is the problem

Ah.. in that case... this is even more clear cut because I have been using DD and midi regions all day without an issue..

So, using my earlier method.. but instead using just Drum Designer and some midi regions then no issues at all here when LLM is On of Off. Everything stays nice and tight, timing wise.. against both the metronome and a separate EXS24 based click track. even after 15+ minutes of playback...

So, Im thinking this is not a general LPX bug as such (because its not easily reproduced) but somehow you have something screwed up settings wise or your Audio Interface drivers are having an issue though admittedly, I'm not sure why it would only be affecting the DD plugin for you and not anything else..
