Need Help With Lag Options

[tburn]

Hi, idk really where to post this so im sorry if this is the wrong place. But I have a mac, and I run GarageBand and Ableton live. When I play via my midi keyboard connected through the usb hub, its fine. But when I plug in my guitar through the jack next to the headphone jack, it lags pretty bad. Same thing when I run my synth through that jack. How can I take the sound from my hardware synth and guitar into my DAW's without lag? Like what exactly do I need to buy, as cheap as possible haha

Thanks,
Tyler

We could do with knowing a bit more about the spec of your Mac as this could be the biggest impact on lag.
A few things to try though: make sure GarageBand is the only app running while you record and also turn off wireless and bluetooth. (Wireless is a known cause of problems with GB and Logic.) If you're using a MacBook/Pro, plug in or check your power settings allow max CPU if on battery.

Just a little pointer that you shouldn't really plug your guitar straight into the mic/line input as there is an impedence mismatch. You won't get the best sound this way and could end up damaging equipment. (Synth is ok as it is line-level.)
