latency problems

[hally flip]

HEY EVERY ONE !! latency problems ! looked at the suggestions on how to reduce on ableton site but it didnt fix. so messeed about a bit and found that with "DELAY COMPENSATION " unticked is problem solved.

Good for you!!! What system, OS, etc so other can benefit too....

Another way, without side-effects is to not use devices and plug-ins with latency.
Or turn off PDC when recording.
On the good side you're about to find out why there is something called Delay Compensation…

Hi, I'm finding 'unusual' and rather annoying latency/delayed sound playback problems too in Ableton 10. Even when all of my plugs in are turned off.

And found that unticking the 'Delay Compensation' corrected it as well.

Any downsides of this? (Intrigued by Stromkraft's reply!).

I'm using iMac Pro (10 core, 64GbRAM) with High Sierra- should be super fast. My old iMac Pro runs Live 9 perfectly in Sync! WTF!

When I'm multitasking on my laptop I use an Autohotkey script which suspends (freezes) other apps of my choosing running when Ableton is the active window. Completely resolved dropouts I was getting and will allow reducing latency to some degree on many systems.

Here is the script. Install Auto-hotkey and run script. Should work for any Windows 10 or 7 rig,

Change or delete lines with the names of the processes in the script (eg. Notepad.exe) so you have just the names of the processes you want to suspend.

Be aware suspending browsers may cause downloads to be interrupted or cause similar problems with certain apps.m Credit to original author of script (not me).

------------------------------------------------ SCRIPT FOLLOWS. COPY EVERYTHING BELOW---------------------------------------------------

#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.

Hey Dalicus, I am just getting started with Autohotkey - this looks really cool. Are you still using this script? Have you ran into any major issues with using it?
