there’s a white button on the bottom that restarts it, I believe

#1570

Any tips on what to look for in Maiden that could be causing (error: audio engine). I’ve been able to find duplicate engines before but can’t seem to find anything this time. When I run a script in Maiden it doesn’t show an error or duplicate file.

#1571

What script / engine?

Did you ;restart from SC tab in maiden?

Any changes since last working?

more details:

afaik, the screen message SCRIPT ERROR: AUDIO ENGINE is supposed to occur only in one circumstance: the supercollider enviroment failed to respond to the initial handshake from the lua environment at startup. this is almost certainly because of a duplicate SC class, or an SC coding error that prevents class compilation.

but there is at least one circumstance where ;restart from maiden won’t work, which is that for whatever reason sclang or scsynth are failing to launch at all, and the websocket connection to maiden is not made. this can happen if, for example, you have manually killed and relaunched the sclang process and the UDP ports it wants are not available when maiden restarts it from systemd. seems unlikely you would encounter this in normal use.

finally: it is possible that you’re running into an SC crash on startup due to the time sync issue (https://github.com/monome/norns/issues/399). a restart should fix it if that’s the case. (i recently got bit by this on tour, i’m pretty sure, and the workaround was to make sure and perform a network time sync with some regularity, like 1/day.)

Any script it would seem. Everything hangs on loading. did restart I’m SC in Maiden, that showed me the duplicate engine. Deleted that and did restart again and we seem to be back up and running.

One of my norns has seemingly lost the ability to resume a script on startup. Instead of booting to the last open script, I consistently get a black/blank screen, almost as though I had used the bottom button… no other functionality seems affected.

Any ideas how to get things back to normal?

#1574

maybe nuke ~/dust/data/system.state, system.pset?

(other thoughts)

  • if you updated ~/norns from git, run ./waf clean, ./waf build

my main troubleshooting sequence involves opening up three different shells on norns and manually running all the components in order:

/home/we/norns/build/crone/crone
sclang
/home/we/norns/build/matron/matron

to see all the output.

./waf clean && ./waf build fixed me right up.

Thanks @zebra!

dumb question - how is ./waf build different from regular ./waf?

#1577

i think it’s not; build is the implicit default command.

> ./waf --help

waf [commands] [options]

Main commands (example: ./waf build -j4)
  build    : executes the build
  clean    : cleans the project
  configure: configures the project
  dist     : makes a tarball for redistributing the sources
  distcheck: checks if the project compiles (tarball from 'dist')
  distclean: removes build folders and data
  install  : installs the targets on the system
  list     : lists the targets to execute
  step     : executes tasks in a step-by-step fashion, for debugging
  uninstall: removes the targets installed

Hi all.

A couple of times now i’ve had norns power down after plugging in a second controller (2011 arc or an Akai lpk keyboard), both whilst a recent model grid has been plugged in. Grid was mostly unlit at the time.

Just wondering if i should be looking to power down before attaching controllers/devices or if i am likely to damage norns if this keeps happening, whilst powered on?

Currently running norns 2.0.1 (if it makes a difference) and the hardware seems fine still. If there are any other helpful infos i can provide, just let me know.

Cheers :slight_smile:

This is probably a tough and out of scope question: What’s a good microphone to use with my Norns? I want to use it with voice and some percussive sampling.

#1580

I have just been using my field recorder. Occasionally I will use it as a pre-amp with other mics, but more times than not I just use the on board uni mics.

@andy is your norns being powered? battery-powering while hotplugging high-current devices (like grids and arcs) may be problematic depending on the edition (influx current). it’s nothing to be alarmed about, but a limitation of the norns battery to supply enough current for multi-device hotplugging.

#1582

I will be away from home for some weeks this summer and want to take Norns with me to play and learn with it.

Am I right that there is no way to connect Norns directly (via cam connection kit) to an iPad? There are very cheap 4 channel mixer w/ USB out but it feels a bit strange to connect two digital devices that both have USB connectors via audio cables and two DAC/ADC. Plus it’s another thing to carry around and probably would not be battery powered (are there actually small battery powered audio interfaces with at least stereo input). I just want to record Norns and then mix what I have on the iPad. Another way would be to somehow get Norns’ tape recordings on the iPad - but how?

Unfortunately there will be no computer around and I am dreaming of a small setup of just Norns, iPad and a device to play on like grid/keystep/op-z.

Approaching: norns
#1583

right, unless ipad can act as an audio device somehow

yes, i’ve found the irig pro duo very handy with ios/android; there is a smaller mono version. they aren’t super cheap

surely there must be an scp / ssh client that supports downloading to iOS over wifi?

(also i think it would not be hard to update maiden to allow audio file downloads from there. but i shouldn’t promise anything there.)

I’ve just ordered a Roland GO:Mixer to use as an iPad/iPhone audio input device. The older one ($99) is bus powered, and there’s a newer one (“Pro”) that has batteries.

The general problem here is that norns and the ipad are both “comptuers” and not “usb audio devices” so you can’t just connect them together via usb - or even with the headphone/mic input if you have an ipad with a minijack (which requires a line-in TRS to mic TRRS cable adapter)

Search for an iOS SFTP app and then connect the ipad to norns over wifi (norns in hotspot mode I think works).

(I use Transmit on Mac and iOS, but the iOS version was discontinued and is not available at this time)

#1585

i was using blink shell for getting files from norns to ios (i think). it’s maybe overkill if that’s all you need to do, but it’s a really good one.

#1586

I’m pretty sure Terminus on iOS can handle getting files via scp as well.

#1587

Thanks a lot everyone for the insight! I think the iRig duo looks great, has a lightning cable included and also offers MIDI capability, which the Roland does not. The street price of both is pretty close and not too high. Plus I can save on the cam connection kit.

I still have to understand the file system of modern iOS better to understand the wifi file transfer. It is like the cyberduck thing I use for connecting Norns to my computer for installing new instrument updates, right?

My last iPad used a complicated per app folder system that was only accessible via the iTunes.

It’s great to see that this might really work. :slight_smile:

#1588

In Transmit at least, you have to FTP a file to it’s local app directory (which is similar to that older per-app folder system I guess), but then you can easily use Save to Files to save it to the Files app or open it in another app with a “send to…” button.

Look up details about the built in Files app as thats an easy way to save things

(EDIT - looks like you can add specific apps to Files to make saving easier)

Also - yes, what we are describing is exactly like using Cyberduck as you have been.
