Norns: Monitor level issue on script load

I (and a few users) have been stumped by a rather weird problem when loading the latest version of my script Compass (v3.0). Despite the global LEVELS page indicating that monitoring is fully turned up after booting/soft-reset, no incoming audio seems to pass through. If I simply adjust the monitor level on the LEVELS page (like turning it down/back up a hair), everything then works just fine.

From my testing, this seems to have started after installing the latest norns update (200328). Also of note: users have reported that this seems specific to Compass – if they load another script, monitoring seems to work fine there.

I don’t recall making any changes to my script that would have caused this, but all the code is here:

I understand that I could probably set audio:level_monitor() from init to (hopefully) mitigate this, but I’m curious as to why it might be happening in the first place. I’m sure it’s something simple, but I can’t figure out what I might be overlooking.


something must be up with the new param menu

will take a look

Somewhat related (and apologies if this is too much of a distraction) – my script turns off monitoring (and reverb and compression) during its init: because its whole purpose is to do FX processing on that input (and leaving monitoring on would basically be a duplicated dry signal). I would really love to be able to, on cleanup(), set monitoring, reverb, and compression back to whatever the user had them at before they started my script.

I’m actually a bit worried that these bug reports Olivier’s getting may even be my fault, as mine / other scripts like mine are turning some of these shared settings off, and users are blaming Compass instead of us :zipper_mouth_face:

EDIT: reading more, it looks like I hadn’t git pulled norns recently, so I missed that e.g. monitor_level is a param I can use. I’ll update my script to read those values on init, save them in variables, then set them back to where they were in cleanup :+1: This also seems to fix the issue where changing the monitor level didn’t update the LEVELS screen.

EDIT 2: Alright, Pedalboard v1.0.1 is up now, which restores monitoring, reverb, and compression to where they were before Pedalboard was launched :+1:


I experienced this with cheat codes yesterday
