Hey Elektronauts, sad day, my octratrack will not boot. Just keeps going to the test mode screen with the 5 options. Test mode, empty reset, midi upgrade, send upgrade and exit. When I run test mode it’s very short and just goes back to same screen. When I emit reset same thing. Have tried different memory cards, no luck. Please help!
Here is a video of test mode : https://youtu.be/7-qINiX6-lo
Sad indeed. Did you try without the card, demo mode :
Make sure no Compact Flash card is inserted. Switch on the Octatrack while keeping the [ENTER/YES] button pressed. The LCD screen will state that demo mode is being entered.
Thanks for your response and condolences @sezare56. Yes, I can launch demo mode without a card, whenever I insert one of my cards tho it goes to that testmode screen 
sorry to hear that…
i would try to do what @sezare56 suggests, maybe there’s something wrong with the flash card. if that doesn’t help you could try and reinstall the OS. one thing i’ve noticed in the video is that at the end of the logo animation, the graphics don’t seem to be right ('playback:static appearing right below the logo)
mm…could be the card reader got damaged somehow (the pins inside it)? have a read here
