Mezzz 1.2 Dev Notes:

Make sure to update to this one since the knob action is greatly improved. Haptics have been inverted by default, haptic response now has options but not saving user ops yet. The settings menu has resolution scaling options for device compatibility.

  • LED patterns now fully documented in new manual PDF

  • Side button CH switching is now a hold (to avoid bumps)

  • Wired MIDI

  • Settings Menu (Hold center and turn a knob)

  • Haptic Options

  • LED Brightness

    • Now buzzes on out of bounds pulses

    • Other haptic mode is available in Settings menu

  • Sending CC to Mezzz will set that knob value internally

  • Tested for use with Hypno and vidOS multi-controller setup (Requires Hypno 2.4 OR vidOS 2.0)

I keep getting “can’t connect to serial port” errors on a M2 Macbook Air & freshly downloaded Chrome, any ideas?

What have you tried to fix it? Have you followed the flashing directions carefully?

Heres the 2 recommended troubleshooting items from the linked firmware page:

Serial port never shows up? Try activating Programing Mode

Hold the center button while turning the device off and then on to place Mezzz into Programing Mode. No leds will light up in this mode but the port will be visible.

Can’t connect to serial port?

Make sure other programs aren’t trying to use the port, including any IDE, browser, game engine, vj software etc.

I did all of those things carefully more than once yesterday to no avail.

Today I repeated the process and successfully connected & updated the firmware. :ghost:
