Bypassing "Real Time Pre Gen Cache"?

[Winslow Schiller]

Hi All,
I'm running 10.13 on High Sierra and for the life of me I can't stop the Real Time Pre Gen Cache from making a glitch sound when it turns red....which is all the time. No plug ins? Red. Plug ins? Red. Add an Audio Track? Always red. I've tried adjusting the usual suspects and nothing works. Right now, when DP's not even playing? Red. The glitches are recorded on Audio tracks, and that's a real bummer. Isn't there a way to bypass it or at least make it stop? Please MAKE IT STOP. - Winslow

Is anything turning red in the Activity Monitor?

When you say No plug-ins, not even MOTU plug-ins?

What Mac are you running and where are your buffers set?

Hi Mike,

I can open an empty project, add a stereo audio track, and the Pre Gen red light lights up. With nothing running, no plug ins, no nothing. This is 100% repeatable.

Ok but that doesn't answer my other questions.

I'm on a Mac Pro 5.1. Settings do not matter (I've tried 2048 and 1000 "Prime Milliseconds"). Plug ins (MOTU or otherwise) don't matter. Again: if I start from an Empty project and add an audio track (regardless of settings), it'll redline and glitch.

A follow up:

First of all, I had no idea that what I thought was a single idiot/overload indicator was actually three of them:

Real time
Pre gen
Cache

On DP these appear exactly like they appear here, with only a single indicator to the right of "Real Time." 25 years on DP, and I've simply never had to deal with it. As a result, I thought it a single thing: the Real Time Pre Gen Cache. Which, of course, doesn't exist.Therefore, all this time it's been the Real Time meter which overloads and causes audio glitches and drop outs, even with nothing in DP except for a single mono audio track. Pre Gen and Cache (on my DP) do not have an associated idiot light. I can only see these features function in a side window.

I only figured this out after spending about an hour with a MOTU tech, who took remote control over my system to help–to no avail, unfortunately. So, long story short, DP still overloads Real Time processing, and no combination of buffers or other settings fix this bug. - Winslow

By DP 11.1, a large number of bugs were fixed that were never properly addressed in DP 10.
