I’ve just installed a bunch of apps from maiden which worked perfectly fine on first launch however after I put it to sleep and restarted I am greeted with the message error: DUPLICATE ENGINES and none of my apps (new and old) will load. I assume I’ve accidently downloaded something twice but I can’t seem to find where abouts it is.

Nevermind, fixed it :slight_smile:

awesome! lmk if it was something weirder!

also, mind if we close this topic out since it got resolved?

Yeah no worries! All I had to do was delete my duplicate applications which I installed outside of maiden.

I have just plugged my shield in and got the “duplicate engines” error. Yesterday I installed a few scripts that appealed to me…but if maiden is telling me what is installed and what isn’t, then how is it possible to duplicate? I obviously only clicked on scripts that had “install” next to them. Now I don’t know which scripts I have “duplicated”! How do I find out?

sorry to hear about the trouble! maiden should report on which engine is duplicated and where, inside of the REPL window, eg.

/home/we/dust/code/ack/lib/Engine_Ack.sc Engine_Ack.sc
/home/we/dust/code/we/lib/Engine_Ack.sc Engine_Ack.sc

(from help | monome/docs)

to track it down, which ones are listed when you attempt to load which script?


Thanks Dan. Let me just have a look at maiden now…

Fairly new to Norns myself; this error and the method to resolve it is clearly outlined in the help docs. I’ve only had to do it once but from memory I seem to remember that “;restart” in maiden lists the duplicates?

Thanks. Where is the restart button in maiden? can’t see it

you’ll want to type ;restart in the “matron” window (pictured above)


Hang on…now it says “supercollider fail” @dan_derks @rcf


ah dang! hmm. how did you resolve the Mx.Samples duplicate issue? you might just need to power norns down and reboot.

This indicates that something is wrong with SuperCollider, which could be due to various issues. First always just try rebooting via SYSTEM > SLEEP.

If you’re able to load maiden, there are two tabs in the main REPL area (above the >> prompt at the bottom of your screen). The first tab is for matron, the control program that runs scripts – the other is sc for SuperCollider. Click into the sc tab and type ;restart into the REPL. That should show you what is going on inside of SuperCollider.

Thanks dude. I have to go pick up my son now…will try in a bit…
