Norns: help

@Jonny nope it works fine in every other page

@okyeron hmm… I don’t think so - I’m pretty sure I ordered the exact ones from the BOM

Edit: - they are these;

I just realised these are 12 PPR instead of 24. I guess mouser must have replaced them without me noticing, as they have no 24 PPR encoders in stock… is there any software fix for this?

No, very important! Sorry to cloud the conversation!


Had a look into this - I don’t know if this is the right place to post about it because this is related to the norns software.

Inside the lua/core/encoders.lua file, we call util.time(), which is supposed to return a timestamp like


however, on my norns image, when I call this function;

> s = 1576259801
> us = 782489
> s + us/1000000

I get this result, which, when the encoders.process function diffs to find the time between the last encoder change, it gets a result of zero, and thus applies the maximum “acceleration” for the encoder of 6*.

I rewrote the time diff function to diff between seconds and microseconds manually, and this works fine, I can use the encoders normally in scripts again!

My lua version;

# lua -v

I don’t know if this is an issue I should make a pull request for, or if I’m running the wrong version of something, or what… but at least I got to the bottom of it! :slight_smile:

i’ll check this out and see if i can reproduce. are you using the norns shield disk image?

I built the latest image from here -

I guess this might be a bit too bleeding edge and the cause of the issue?

Well, as far as I know everything works, although it still need more testing.
If you run into any issues please let us know, some more testing/feedback is always nice :slight_smile:

Apart from that I’ve noticed some skipping behavior on some scripts as well (16 sliders is the one I noticed it on) from my testing this started with norns 2.2.4. I haven’t created an issue for this yet, will do so this weekend.

[edit] Btw I’m assuming this is on the norns shield. Is that correct? If so we should probably move these posts there, could be confusing otherwise.

Hey everyone.

My “Disk free” is saying 0MB. last time I was using Norns it was frozen in a couple scripts like MLR and Boing, so I forced shut down. Seems like maybe something went wrong. Any tips on how can I sort this out?

suggested disk image is in the DIY shield thread top post

Quick question: To have Norns speak to Axoloti usb to usb ie Awake to sequence an axoloti synth, I would need a host-host adapter like 2host? Or am I missing something?

Axoloti specs say:

Full size USB host port

so I’m gonna say yes - you need 2host or a savila soft usb dingus.

EDIT - but it also says

Micro-USB device port

but I dont understand what that means here. Maybe @TheTechnobear can chime in with details?

micro-usb serves connection for Axoloti software, a power source, and act as a class compliant midi device.

So try that?

Axoloti can act as a usb host and usb device.
So you can plug it directly into Norns without any adapters etc.


I use a Roland UM-ONE from Norns USB to the midi in on a Scarlett 2i4 to control soft synths on my Mac.

Thanks! I ordered a 2host so I think I’m good! Besides connecting Norns to my computer, I’d like to connect to my iOS devices. This seems to be exactly what I need.

Just wondering is it possible to clock norns / norns shield?
Using a cirklon as midi master so could use midi or cv… Any recomendations on this particular setup?
Also does it depend on which app your using or is it a global clock for the whole norns system?

It depends on the specific script you’re using.

There’s some talk of global clock things, but it’s not in the current system.

How are people currently doing backups of scripts and the tape folder on their Norns?

I’ve been doing scp transfers typically from my laptop but am wanting to do this a bit quicker (and possibly right before a show if I realize that I have no space left in my storage to actually record a show using tape).

I really like rclone ( for backups on my desktop so now I’m using rclone on the Norns directly to bundle up items in the tape folder, timestamp the folder, and upload to cloud storage. Then I can clear them off of the Norns storage. I’m thinking maybe I’ll make a Norns patch that can do this with a button press from the Norns itself and clear out the tape folder recordings.

Maybe other people have better ideas though?


I’ve been meaning to work out how to mount a small USB drive for this kind of thing. I believe it should be possible.

@okyeron @TheTechnobear thank you for the help! I can confirm I can send midi data and power from norns with just a simple micro-usb cable to Axoloti’s micro-usb port. Currently playing with CS80 emulation patch for Axoloti and Dunes to sequence. Very happy it’s so simple :grin:

Axoloti also has a midi through object…lots of possibilities!!



yeah, axoloti is great for this kind of stuff…
not only can it act as a usb device (and host/din), but its bus powered (and draws very little mA), so it really is plug n’ play.
I love the fact, its low latency, so really cool to use as audio fx processor (or synth)

also, @TomWhitwell AXOC ‘case’ is an excellent addition.

this is great for something like norns, as it gives you 6 more pots, 3 buttons and a joystick but in a small/portable form factor .

Axoloti was released 4.5 years ago… I still use and love mine, and I still think its a pretty unique product - a secret gem :wink:


Tape recording is not working. when I press start immediately stops.
