I'm not sure if this is a hardware or software issue. When I open a file and play it, the first time it plays there's a glitch in the cellos and/or basses at measure 69 (the work is in progress and I am up to around measure 130 or so). But if I go back and play just those measures or the entire sequence, it plays fine for the entire session.
I've done a check on my hardware in terms of how well it's able to handle audio and everything looks good. Though I've been managing a studio for nearly 40 years, I'm really stumped as to what causes this.
The DAW is connected to one other machine via MIDI through Ethernet and audio returned to the DAW via ADAT. The 2nd machine is dedicated solely to the VSL Orchestral Cube.
Windows 10, i7 CPU, 32 GB RAM, 2 SSD drives
2nd Computer:
Windows 10, i7 CPU, 32 GB RAM, 3 SSD drives
The two computers are connected via ADAT, each machine has a dedicated sound car, the DAW has an RME UFX II and the 2nd computer has a MOTU LP32. I've tried changing the audio buffers from 512 to 1024 but that doesn't resolve it.
These are dedicated computers, used for nothing but music production.
I really don't know if this is an audio glitch or a MIDI glitch. It sounds like a note gets cut off and I hear a little short "pop". As I said, this only happens once, when I playback the file the first time after I turn the computer on and begin work.
Any thoughts from what might be causing this?
Thanks,
Jerry
