Pro Tools 11 - Playback Problems and Latency

[Mmanzano123]

Hello guys!
I’m having a lot of problems with Pro Tools 11 when both recording and mixing.

PC Setup

• CPU: I7-770 3.6 GHZ
• MB: Z270 Tomahawk
• 32 GB Ram
• System HD: WD_BLACK™ SN750 NVMe™ SSD M2 1TB
• Sessions and VSTS HD: Crucial FCCT1024 SSD 1 TB
• Audio Interface: Focusrite Scarlet 6i6 Gen2

My session setup is the following:

1-3 VST instruments like Kontakt , Omnisphere , etc.
3 Mono tracks with Guitar Rig VST
10-12 Mono tracks with 1-2 plugins each (EQ + Dym)
2 Aux Inputs with Reverb and Delay
1 Master Track with an L2 compresor

Recording

• I get Latency, even at low buffer size levels ( 32-128 samples)
• When activating Ignore errors during playback or minimize aditional I/O Latency from the playback engine

• I get Jitter, clicks, pops.
• Sometimes playback just wont start, the play button from the transport menu starts blinking.
• This makes it impossible to record properly while using MIDI and Virtual Instruments

Mixing

• Sometimes I get the same Playback issue at high buffer size levels (1024)

When I check the System Usage to see my CPU usage, it show 30-35% tops, so I dont know why my system is reacting this way.

I’m attaching a picture of the CPU load to the post.

Needless to say that if I use Cubase or Reaper this doesn't happen at all.

If anyone can help me sort this out so I can use my Pro Tools properly , I will really appreciate it.

Thanks!

You didn’t specify what your operating system is. How are you hosting VSTs?

I am not fond of putting sample libraries on the same drive as sessions. With only 2 drives, I would put those on the system drive, OR, try putting the session on drive C: (this was not good in the days of spinning drives, but a fast SSD should be fine with it).

Set drive cache to 4-6GB("normal" is actually none)

Freeze or Commit the VI tracks as soon as each is recorded to see if that helps(if it does, then that indicates my first comment may have merit)

My OS is Windows 10 Pro.
Then regarding Hosting, I'm just using Instrument Tracks with inserts linked to Midi tracks .

I dont know if that's what you meant by "hosting".

VST plugins don’t run in Pro Tools, it only “sees” AAX-64 plugins. How do you get PT to see your VTSs? (I use BlueCat Patchwork)

Ohh now I see what you mean. Just a notation mistake, by VST I meant Vsti (Virtual Instruments). They are all AAX.

By the way, Pro Tools 11 is not officially qualified for Win 10.That doesn’t necessarily mean it won’t work, but you won’t get Avid support (as if!)
12.4 wasn’t qualified either, but it worked on W10 just fine. Consider running in compatibility mode.
