norns: help

arm record by holding key 2 and hitting key 3. and again to record, and again to stop.

Key2 on the Norns? And key 3 while hitting Key2 or after? Sorry I’m having such a hard time figuring this part out!

If I hit key 2 it toggles between Volume/speed mod and rec level/overdub. key 3 doesn’t seem to be doing anything that I can tell

most shipped with around 80% battery. battery % indicated on the LEVELS screen in the upper right.

different engines/scripts use different amount of CPU hence different amounts of power. you can see the power drain by holding KEY1 in LEVELS. the battery is 2250maH so you can do the math of how far you’ll get given your current consumption. (it also shows charge rate, as a positive number)

and no, there’s no indication when charging when the thing is powered off. unfortunately there wasn’t a quick (cheap) way to implement that in the circuit.

yep, the keys on norns. while in REC mode in levels you hold down key 2 to access the record functions, and you execute them by hitting key 3 while still holding key 2. switch between REC and PLAY modes by holding key 2 and turning encoder 3. you’ll see this visually on the screen as well. maybe you’re still in play mode?

this info and more helpful navigation basics is on the legend (levels and tape section) that came in the box with norns, also pdf version here

Thanks for your help. When I open MLR, with the top left button lit on the grid I know I’m in rec/speed mode. the norns display is showing REC>1. If I hit key2 it will go between volume/speed mod and if I hit it again it will say rec level/overdub, while still showing REC >1. If I hit key2 while turning encoder3, it just adjusts the speed overdub level or speed mode, depending on which view is visible.

EDIT - I see, you are saying to do this from the levels menu, not the MLR menu

with the tape>REC and monitor level off, shouldn’t I hear the source when I enable the REC column on the grid?

Of the 1GB RAM, how much do you reckon is a good safe amount to take up with WAV files?

right now MLR uses a shared sound buffer for all 16 clips-- if you load a super long file (16 seconds?) it’ll overlap into the other buffer regions. this is something i’ll address with updates.

but if you meant eMMC (disk space) there is 2.2g free (indicated in SYSTEM). you can probably fill it mostly with sound, but then you won’t have any room for TAPE (direct to disk).

@stripes is talking about the direct-to-disk TAPE function, which is in the menu system, leftmost screen which is LEVELS.

mlr has a whole different interface. quickstart here: Approaching: norns - #1391 by tehn

and real docs coming within the next 2 days. (we are basically finished building/shipping, hooray!!)

regarding line noise when usb connected to your computer, i bet the truck discussed in this post would fix things.

External grid power - ext5v alternative Monome

There’s some useful information on this in the Ansible & grid / power issues thread, here specifically: I took this approach (a USB Y splitter with the red power line cut in the data cable) and it’s been working ok for me. Plug my grid into the splitter, and then run the power end to a simple 5V apple phone charger and the data end directly to Ansible. My cable’s a little finicky, so I’d love to get an offworld if they happen to come back in stock at some point. Edit: As @tehn and others hav…

i will verify later.

stripes · 2018-05-30T01:48:20.996Z

ah yeah i see, didn’t realize you were talking about MLR. thanks brian! take a break soon : ) you guys r killin it out there!

Thanks Brian. That was a big help. One more question, following those instructions I’ve been able to record on tracks 1 and 2, but not 3 and 4.

Yes, maiden and hotpot mode work perfectly!

ppqq · 2018-05-30T02:43:59.845Z

also vis a vis wifi, a couple more thoughts:

if you’re far from your router try getting closer
if you can get to your router’s configuration, try switching “compatibility mode” on

otherwise, hotspot is solid

For a moment I thought hotpot was something new and delicious.

Is it possible to edit SC engines from Matron? I haven’t found a way.

I synced everything to USB and see that the engines live in dust/lib/sc

What’s the current recommended workflow for creating/editing SC engines? Will I just need to sync to/from USB for now?

hypnosapien · 2018-05-30T02:54:38.529Z

Ha! I was too distracted by norns to notice how hungry I am…

bpcmusic · 2018-05-30T02:54:48.884Z

ppqq:

There’s a bug in the shipped wifi setup script that sometimes wrongly reports connection failure. The good news is it’s fixed and should be better on the next update. In the meantime, it’s worth checking if it’s actually connected and just says it failed.

I can confirm this. Failed connection on my local network, yet I’m editing in maiden and replying to this post at the same time. Since you can’t get the IP when it is pseudofailed, you can use the norns.local (on macs).

Currently not possible. I’m using the SuperCollider IDE on a Linux laptop for engine coding (with matron running on the same laptop without UI), but it is also possible to access the norns system via ssh and even mount the filesystem with sshfs, then edit the files remotely. You’ll have to reload SC class library manually from the REPL in the latter case.

Unable to get midi (keystep) to work in earthsea tonight, not sure if I’m doing something wrong/dumb. loaded earthsea, connected midi, no output. the parameters seem like they should be fine and I’m able to use the keystep with hello_ack just fine. Tried back button restart as well as sleep and also plugging in midi at different points. thoughts?

artfwo · 2018-05-30T03:15:53.839Z

The scripts currently only read notes from midi channel 1. Is your keystep using channel 1 to send the notes?

speakerdamage · 2018-05-30T03:24:12.471Z

strangely I just tried it again after about 20 mins off and it worked without switching channels or anything. but I did just switch channels and see that only channel 1 works, so thanks for that info.

adrianf · 2018-05-30T03:37:38.869Z

Neat! Can you do any of that through usb/tty?
