My machine locked up numerous times in my testing process, so that whenever I scrolled past the bad user preset, it hung and the TB-3 had to be restarted. This was fixable though by writing a known good patch over the bad one. However at some point the machine wouldn’t even power on and none of the startup modes worked. Uh-oh. What did work was holding [STEP REC + REALTIME REC] while starting and this boots you to a developer/debug mode, where choosing option 6 initiates a factory reset. But there’s a much easier way if your machine still boots and if you don’t mind returning all user patches, settings, and patterns to factory default:

• • • • • hold [REALTIME REC] + restart
        • display reads “rSt” and PLAY/STOP button is flashing
        • press the PLAY/STOP button to confirm or restart to cancel

Pretty easy and straightforward. If your machine won’t access this mode, you can also activate this function with the developer mode catalogued below. There’s a lot more hidden in the startup modes, and here’s all the information I could find about them. (The Global mode information can also be found in the front panel guide.)

ALL KNOWN TB-3 STARTUP MODES

(all modes accessed by [holding] a button or buttons and restarting)

1. 1. GLOBAL SETTINGS: [SCATTER]
      • set these global parameters:
        1. MIDI channel
        2. MIDI clock source
        3. MIDI OUT is also MIDI THRU
        4. PAD Z sensitivity
        5. Master Tune
        6. LED demo
   2. BACKUP/RESTORE PATTERNS: [PLAY/STOP]
      • here you can backup and restore all the patterns from your device. copy the files only, not the folder. refer to the firmware update document
   3. FIRMWARE DISPLAY: [TEMPO]
      • the firmware version is displayed until you press START/STOP
   4. FACTORY RESET: [REALTIME REC]
      • press flashing PLAY/STOP to confirm or restart to cancel
   5. FIRMWARE UPDATE: [KEYBOARD + PTN SELECT]
      • refer to the update instructions here:
   6. DEVELOPER / DEBUG: [STEP REC + REALTIME REC]
      • once the machine starts, the display reads N-1, and there are 6 options to choose from using the value knob:
        1. N-1: Display the current firmware version.
        2. N-2: USB test mode. Display reads “USB”
        3. N-3: LED test mode. All lights on at their brightest.
        4. N-4: Touchpad calibration, followed by a test with a loud sound even if you turn down the volume, followed by a factory reset. Left side green touch pads are lit, three dashes in display
        5. N-5: Display reads “OUT”
        6. N-6: Factory reset. Same as holding REALTIME REC and restarting.

If you find any more startup modes, let me know.
