I reported this issue to Elektron, just curious if it affects other units as well:
Make sure your monitors aren’t cranked way up.
- (optional, but ideal) Start a new project
- Leave the pattern empty and transport stopped
- Go to the record page
- Set SRC to EXT L, EXT R, or EXT L&R
- Turn MON to YES
- Wait and see if you get random snaps, crackles, and pops.
- The pops should be audible and visible on the level meter.
The pops can be very intermittent so you may be waiting a while. Sometimes mine will go a minute without doing it, then do 2-3 in a rapid succession every few seconds. It’s totally random. Mine does it even if no cables are plugged in.
