Will get to work as soon as my crow arrives! I hope it will not be stuck in customs for too long.

Anyone know if Kria will be one of the scripts that is Norns/Crow compatible?

Building my first modular rig, and if crow can run Kria from norns, i think i’m sold on buying teletype over ansible.

I don’t know if anyone has investigated what it would take for Kria (running on norns) to drive a modular via crow but that seems fairly doable at first glance. One would be limited to two voices since crow only has four outputs.

…unless of course the target was Just Friends running in synth mode (via crow).

I think it’s worth noting (for clarity) that in the above scenario Kria wouldn’t be running directly on crow. Norns would still be running Kria and handling interaction with the grid. Norns would then simply be using crow as an expander to produce CV and gate signals.

I’m assuming there wont be an i2c cable in the box with Crow, is my best bet just DIY’ing one to connect it to Just Friends? Or is there a standard cable I can grab at an electronics shop (where would look for DIY parts too).

link crow to Just Friends (Whimsical Raps) through an i2c cable (or powered bus)

Powered bus… I have a makenoise power bus, does those mean I don’t even need an i2c cable?

i2c ‘jumper’ cables can be found on the cheap! Just show your local store this:

Premium Female/Female Jumper Wires - 20 x 6" (150mm)

These female-female jumper wires are handy for making wire harnesses or jumpering between headers on PCB's. These premium jumper wires are 6" (150mm) long and come in a 'strip' of 20 ...

PRICE: $1.95 USD

The shorter the better, so long as extends between your modules, I don’t regret gettin multiple sizes.

The powered bus will be something like the @okyeron’s tt-busboard jr or the hard to find teletype backpack, or even @bpcmusic’s txb…

What are these things? Follow @tehn’s advice and read this AMAZINGLY helpful thread put together by @okyeron :

A user's guide to i2c Monome

A user’s guide to i2c modules/devices Prepared by @okyeron, @scanner_darkly and @justmat A growing number of devices are making use of the i2c protocol, so here’s a simplified users guide to help monome/modular/music people navigate this sometimes confusing space. Please add questions and comments and we can try to update the main post as needed. what is i2c? i2c is a communication protocol - it’s a way for devices to talk to each other, like MIDI or USB. Some wikipedia for reference: i2c …

It can be intimidating at first, but once you start wrapping your head around it, the typical reaction is, “Oh, that’s all this is?”

Plus, since plenty of people have been patient and kind with me on this forum, I’m happy to pay it forward. Feel free to ping me if it still doesn’t click. I’m no expert, but I feel like have the basics down pat.

I ended up going with these 3 pin jumper wires https://www.sparkfun.com/products/10368 because I didn’t want to deal with worrying about using electrical tape or heat shrink tubing to keep 3 separate wires together. It’s not labeled as such, but when you order a premade i2c cable this is what you’re getting.

Found the jumper leads at my local. Thanks!

@dansimco the only thing I will add is to make sure the wire lengths are long enough. I’ve been trying to sort out my 16n Faderbank i2c control of my ER301 and, because of the position of the i2c jack on the faderbank and distance from the back of the 301, its definitely not a stable connection. I even found that when I had teletype, Just Friends, and Ansible with a teletype backpack, it was a stretch to get the i2c cable i had on hand to where they needed to be…i still havent gotten i2c to work at all, but everytime someone mentions it they talk about how its fiddly and the shorter the wires are the better, but I’m not sure where the tipping point is…
