port of Kria from Ansible to Norns

This is a very straight port of Kria from Ansible to Norns. It’s basically a direct translation of the original source into Lua. It would really benefit from some UI work - I’m thinking of adding a screen to support editing scales next (so you can see what notes you hare!). Contained within this is the Kria code as a library that can be included in other projects


grid, midi

Thanks so much for updating this. Love having Kria available outside of my case

I know little of Kria, but that video is amazing.

Would it be possible to add a few more tracks?

Loving it! Opening up new ways to use this old synth that I’ve had for a good 8 years.

A few little things that I noticed:

When I turn a note off I can’t turn it on again unless I turn on another note in the same step first.

I’m not too sure if the scales are following the same system as on ansible kria. On ansible the left column is the same note as the row below, the next one to the right is a semitone above that, and so on. On this version it seems that the left column is a semi tone higher, then the next one to the right a whole tone, etc. Not sure how much it matters but I guess it might to some.

There seems to be no ratcheting (a feature I use a lot!).

It would be amazing to have one of the encoders controlling the tempo!

Your idea to have the screen show what note is playing and to show the scales is brilliant too!

I think porting kria into norns is fantastic, as it’s such a great composition tool and I’m sure many of us are very familiar with it as an interface now too. Love your work. Wish that I was more savvy so I’d be able to help with bugs!

I’ll let you know what else I notice in using it that might not be quite right. Looking forward to trying this on my M4000D Mellotron!


Thank you for bug reports. I’ll have a stint fixing them early next week. Glad you are finding it useful

I’ll add in ratcheting too!


Thanks for porting this over junklight! I’ve been intrigued by Kria for awhile but alas no Ansible, so I’m excited to play around with this. Gonna give it a whirl later tonight.

how hard would it be to implement a numerical tempo control so as to set the starting point for the tempo. It seems it defaults to 110bpm

Should be easy. I’ve got a number of bits & pieces I want to do to it. Not least a Ui for scales so I know what notes it’s playing :slight_smile: but i’m a bit overcommitted just now so all in due course…


Thanks a lot @junklight for porting KRIA. I was playing with it, awesome sequencer. Just one issue though, the scale had no effect on the notes of my sequences. Am I doing something wrong or is it a bug?

confirmed: scales and ratcheting not working yet

@junklight really great! i’m so happy to have up-to-date kria ready to go, outside the modular!

Is there maybe somewhere guide/manual how to use Kria?
