This is really backwards.  Logic can handle guitar+bass+other various inputs with no perceivable latency BEFORE utilizing the latency-free button on the transport. Maintage, designed for live performance, however cannot handle a single audio source without noticeable latency.  This is absurd. I can get down to 8ms fine tuning things, but my CPU is at 90% and it's still inferior to running in Logic. 

 

How does this make sense?

 

Anyway, since I know I can get to 8ms on my aged laptop and Konnket 6, what gear is required to actually use this program.  I know it's possible because Tretn Reznor's apparently been using it for a while (since LITS IIRC?).

 

Thanks.

    Hi

     

    A few Q's for you:

     

    What audio interface are you using (and are you using the same one when you report lower latency thru Logic)?

     

    Do you get any better/different results when using the built-in audio?

     

    Does this offer any help: http://support.apple.com/kb/HT5155

    Many many pros are using MainStage live, I've worked with many of them and latency is typically not an issue for them - or just something they work with.

     

    How do you define bad latency in MainStage and Logic? By looking at the numbers? The world is not that simple and - yes - there will always be latency. If you use MIDI, the output latency is what is important (because that's the only one controllable, the MIDI input latency is defined by the MIDI hardware); if you do audio the roundtrip latency is important. The numbers itself can not necessarily be trusted, especially with external audio hardware it is often wrong, because some drivers _lie_ about their latency to the system. The only real way to find out is by measuring it with an oscilloscope.

     

    The main factor is the buffer size, which you can adjust depending on your need. I wouldn't just move it to the minimum and the driver latency also to the minimum, because it has an effect on the CPU.

     

    I can tell you that at identical settings Logic _has_ no better latency than MainStage. Period.

    Argl, yes, the Adaptive Limiter has an adjustable latency on the output it affects everything. MainStage has an option to show the latency for each channelstrip under the channelstrip, it's worth to check that.

     

    The limit is around 100%, don't consider any number as bad or good. It is more a headroom for how much more you can add/play, but not where you are at.

     

    The current Lady Gaga tour uses several instances of MainStage (all keyboards and the drummer use them), all run on MacBook Pros. MacMinis are also very common if you want a rack installation. That NIN is using an Xserve is new to me, it's the first time I've heard about using an Xserve with MainStage.
