40h should work fine, but when was the last time you knew it to be working? does it give the powerup blink?

#62

good question, thereā€™s no blink, few buttons are green, rest is off

#63

and when was it working last?

#64

before i stored it in a box on the shelf, approx a year ago

#65

tried it on another machine with 10.13 and other usb cable, same problem,
so I can assume itā€™s broken ?

Happy Solstice weekend :star2:

So, thought Iā€™d try and join the arc + grid computer party, but Iā€™m experiencing similar connectivity issues to the above mentions.

The Issue
My arc and grid arenā€™t reliably recognized by computer.

What Iā€™m Using

  • Iā€™m using the 2015 grid and 2016 arc on a Mac running 10.14.2 (18C54) with Max 7.3.4 and serialosc 1.4.1
  • I have also tried sudo rm -rf /Library/Extensions/FTDIUSBSerialDriver.kext followed by a reinstall of serialosc
  • FWIW, I say Iā€™m using serialosc 1.4.1, because thatā€™s what I downloaded and installed, but truthfully, I canā€™t figure out how to use -v in Terminal to confirm thatā€™s what Iā€™m using.

What Happens
Often, when first restarting the computer, the arc will light up like this:

arc-lights-post-reboot

Hot-plugging results in the lights briefly flashing upon replug, then staying off. Iā€™ve been unable to determine a pattern of behavior, so Iā€™ll just recount my last experience:

  1. After reboot with arc remaining plugged in, open arc-test.maxpat. It recognizes the arc:
  2. Open Ableton and load ArcLab. Arc is still recognized.
  3. Quit standalone Max. Arc still recognized.
  4. Open ArcControl in Ableton. Arc still recognized.
  5. Hotplug arc. Still recognized.
  6. Hotplug arc again. Still recognized.
  7. Unplug arc and plug in grid. Open Gridlab Alfred. Grid not recognized.
  8. Unplug grid and plug in arc. Arc not recognized.
  9. Hotplug arc. Still not recognized.
  10. Restart computer. Get the ā€˜there was a problemā€™ dialog box upon restart. Arc lights up as per above photo.
  11. Open Ableton and load ArcLab. Arc is not recognized.
  12. Unplug arc and plug in grid. Open Gridlab Alfred. Grid recognized.
  13. Hotplug grid. Not recognized.
  14. Unplug grid, plug in arc. Arc recognized.
  15. Hotplug arc. Arc not recognized.
  16. Unplug arc, plug in grid. Grid not recognized.
  17. Use breath to move disappointment through body and into earth.
  18. Go back to lines to ask for help.

And Iā€™m able to provide any more logs and such, Iā€™m just not sure what to run and what itā€™s actually doing, so Iā€™ll need some hand-holding.

Thanks ~

by grid not recognized do you mean itā€™s not showing up in the drop-down bit ? or just no light things happening ?

this might be plenty deep in the dumb & obvious zone but i get stuff not connecting in m4l in current macos occasionally and I quit ableton then quit max7 & that seems to make everything happy again

&& the arc lights flashing when you plug it in is just the fun thing that happens when you plug it in nothing buggy there

Ah, good question. By not recognized, I mean not showing up in the dropdown.

#69

ah - yea a restart of max (which doesnā€™t happen w/ a restart of ableton) has never not fixed that 4 me but ĀÆ\ (惄)/ĀÆ

#70

also if this is an inside scoop of lightbath ableton edition Iā€™m v here for it

Ah, wait. Howā€™s that?

So, youā€™re saying that I should restart Max, and that quitting and reopening Ableton doesnā€™t restart Max for Live?

And what are the steps to restarting Max for Live?

And for the record, I was also testing with Max standalone and quitting and restarting Max hasnā€™t made the device available in the dropdown.

#72

Ha! Yes. It is. Thanks for the support :hugs:

eep this might prove youā€™re having a different prob then me, wish I had my grid on me to try n reproduce something.

yeah on live9/max7 on mac when you drop a m4l device in you should see max launch and it should pop up in the Mac dock at the bottom, and you can right-click and quit, which closes max

anyone else running grids on current macos this might be beyond me ?

#74

Ah, understood. I had forgotten to mention that Iā€™m running Live 10.0.5, which has Max integrated within the application.

#75

I did have an issue once which sounds similar to yoursā€¦ unfortunately restarting Live and/or my computer cleared it up completely.

#76

that arc photo seems like a hardware bug that slipped out on a very small batch of early units (of which i thought all were fixed). e-mail info@monome.org to follow up-- does this arc work 100% of the time with ansible?

#77

also seems like youā€™re still running the OEM FTDI driver. the apple one works.

remove this way:

sudo rm -rf /System/Library/Extensions/FTDIUSBSerialDriver.kext

and for good measure:

sudo rm -rf /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext

might help i hope

#78

Thank you, @tehn. I know you juggle a lot. I appreciate the attention and care you put toward the community.

So, about the stuff. I ran those two lines in Terminal. The first was successful, and the second returned this:

ā†’ sudo rm -rf /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/MacOS/FTDIUSBSerialDriver: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/MacOS: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Resources/English.lproj/InfoPlist.strings: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Resources/English.lproj: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Resources: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents: Operation not permitted
rm: /Library/StagedExtensions/System/Library/Extensions/FTDIUSBSerialDriver.kext: Operation not permitted

I checked to see whatā€™s where:

ā†’ mdfind -name FTDIUSBSerialDriver
/Users/bryannoll/Downloads/FTDIUSBSerialDriver_v2_2_18.dmg

Thatā€™s good, right? Just the installer.

I then reinstalled serialosc. And restarted. And during the restart, the computer shut down entirely. So I started back up and it shut down again. So then I unplugged the Arc and booted up in recovery mode to run some first aid in disk utility. It all checked out fine with no errors, so I restarted.

I then waited until opening Max (arc-test.maxpat) before plugging in the Arc. Still not recognized.

So I ran this again:

ā†’ mdfind -name FTDIUSBSerialDriver
/Users/bryannoll/Downloads/FTDIUSBSerialDriver_v2_2_18.dmg

Is that still the expected result after having installed serialosc? I figured the Apple one would be listed, but I guess itā€™s named something elseā€¦ right?

Soā€¦ any idea of a next step?

#79

Ah, thanks. Iā€™ll email about it.

The answer to your question is ā€˜I think soā€™. Iā€™ll expand more in the email.

Hi Here!

So long time not being there!
Got a brand new laptop now with max7 and want to reinstall my grid and use my patchesā€¦
Got an early 2011 128 walnut (old usb connection and first varilight)ā€¦
Installed serial osc, opened patch randomly (meadowphysic), but grid not recognised :-/
Any basic ideas??
Thanx a lot!!!
