Can't Change Buffer Size?

[sajack23]

Hey guys I'm having an issue with changing the buffer size. When I go to setup, playback engine, H/W Buffer Size I get the option for 512 samples, but when I click it there's no other options for samples. It only gives me 512 samples....is there a reason it's doing this, and if so what do I need to do so I can change the samples/buffer size?

Here's everything I'm using and running:
Windows 7 64-Bit SP1 Computer, Pro Tools 10, Focusrite Saffire 6 USB Interface, KRK RPG2 Rokit 8 Monitors, M-Audio Venom, Native Instruments Maschine, Kontakt 5, Reaktor 5, Guitar Rig 5.

I appreciate it if you could help me, thanks guys!

HI.
Change the buffer size using the MixControl software to change the buffer size.

I think u have to quit pro tools to change that - to b honest I leave mine at 512 and just change the one inside PT - I never mess with the one on the mix control

Yeah I've been using the mix knob on my interface, and when I do that the delay goes away. Except, the downfall is when I do that, I can't hear the other tracks while I'm recording, and I can't hear any plug-in/effect I put on a guitar as well. Is that what mix control is? I'm fairly new with this.

The buffer size is changed from the Focusrite control panel. This can be access from your Start menu in the Focusrite folder or, via the Control Panel button in Pro Tools' hardware setup dialog.
