Error during Stems Creation in Denon Engine DJ on MacBook Pro M4

Hi everyone,

I’ve recently updated to the latest version of Denon Engine DJ, which allows me to create stems for the tracks in my collection. However, I’m running into an issue during the stems rendering process.

Here’s my setup:

  • MacBook Pro with an M4 chip, 512GB SSD
  • My music library (mainly AIFF files) is stored on a 2TB external hard drive

The problem: I can’t render more than 300 stems at a time because my internal SSD gets completely saturated during the process. To continue, I have to use Onyx to clean up my disk, restart my Mac, and free up space that seems to be used as a temporary buffer during rendering.

Does anyone know a workaround for this or how I can optimize the process?

Thanks in advance for your advice!

This seems like the same problem as I’ve been having. It looks like it is happening to a few of us, so I’m not too sure what the difference is between us & the majority of the apple silicon users here. But I’m basically doing the same as you, try clear / seriously reduce the purgeable size on my internal in order to get stems to render. It’s been quite a headache. Here are some link of others having similar (if not the same) issue as you: Engine desktop not cleaning temp files after stem processing on mac?. 'Your system has run out of application memory'

I am also getting a stem processing error on large batches processed directly to my thumb drive. Restarting my m2 Mac fixes it temporarily.
