Norns shield

[Quru]

Got my Shield up and running, I just hadn’t realized I needed a micro sd card instead of regular sd card, fortunately my Morphagene could lend me one. This is clearly on error on my part as I didn’t check the specs for RPi 3+ properly, but this could be worth mentioning on the product page, even though the link there does go to microsdhc card on Adafruit.

Hello I started having some noise peaks, they are louder if I wiggle around the input for power supply.

The adapter looks like this:

Please help =[ I think I didnt have this issue before. All I did recently was just updating the shield via menu. Thanks!

try turning down the MONITOR level and making sure MONITOR isn’t fed into the reverb. the system has the ability to digitally amplify the input greatly, so if your settings are badly tuned you’ll get a lot of noise.

Thank you so much!!! I dont see those peaks on the shield now but I can see regular jumping in ableton to about this level

Can I do anything more about this or just forget about it because this noise is inevitable? One more question: the norns unit works a bit better in this matter than the shield?

[tehn]

you may have ground loop issues. can you try powering off a USB battery?

[benjaminz]

howdy, any way to switch the norns shield output to mono? i see the monitor mode setting but it doesn’t seem to have any effect on the output.

ah it’s for monitoring input! duh. thanks

[tehn]

as it happens, there’s not a mono output mode.

monitor mode is for input.

I received my Shield yesterday (which arrived faster than expected from the US to Japan) and built it this morning. The most complicated part was peeling the acrylic cover . Very nice kit, perfect for people like me with no time and space for soldering…

It worked right away of course, even when powered with my small portable phone battery (that outputs about 2A, I’ll see if that’s still enough if I power USB devices at the same time).

It’s really been a delightful experience so far (the maiden web interface is really a clever and painless way to manage scripts), thanks again to everyone involved in this project.

Hi there folks, hope you are all safe and well out there? I wondered, can Norns Shield be a sound processor e.g can it take audio in?

[blueroses]

Absolutely! Shield has two 3.5mm audio connections - one in and one out. Plenty of scripts do recording and live sampling with interesting results

Amazing, I am looking to use it to bridge the gap in the Polyend Tracker as a looper. My hope is to be able to use like a little Zoom recorder and loop inside the Norns Shield and then record into the Polyend Tracker, sound possible? Cheers!

I’m not super familiar with Polyend but Norns has a system-level audio recorder in Tape which is pretty basic (just records and plays) but does the job especially for recording from internal scripts. There are also specific scripts such as Reels which is kind of an emulation of the OP-1 tape recorder, and any number of interesting sample/delay/loop options like Barcodes and the mighty Cheat Codes 2

edit: another thing which i think is really great about norns is the granular control over different levels - ie. separate volume controls for input, output, internal audio output, monitor (audio through) output etc. Makes it very easy to handle audio as it passes through the system imo.
