Online Video Looper Pedal

This is a DIY clone of the Vidami Pedal by Utility Design giving you handsfree looping and playback control on Youtube and Vimeo videos. It features one more button and also a bank switch to switch between 2 sets of keymaps. I personally use bank 2 for mapping the foot switches to specific functions in my DAW.

Parts to get

• 1x Arduino Pro Micro
• 1x 1590XX or 1590DD enclosure
• 6x Soft momentary footswitches
• 1x Toggle Switch On-On
• 7x 10kOhm resistors
• 1x USB cable (USB-A to Micro-USB)
• some wire for soldering it all together

Hardware Installation

Arduino

• check the pin layout of your Arduino (Pro) Micro
  • NOTE: the one linked above is different from the official one
  • pinout for above linked Arduino Pro Micro
  • latest pinout for official Arduino Micro
• connect / solder wires to
  • 5V pin
  • GND Pin
  • 7 digital inputs
    • e.g. 5, 6, 7, 8, 9, 10, 16
    • if you choose custom ones you will have to modify the Arduino code
• connect the other ends to your footswitches and resistors as shown in the following schematic:

Enclosure

• drill 6 holes for the footswitches
• drill 1 hole for the toggle switch
• drill a hole for the USB cable
• mount the Arduino Micro so it won't move (e.g. a small breadboard)
• mount the footswitches
• mount the toggle switch

Software Installation

• load and flash OVLP.ino onto the Arduino using Arduino IDE 1.8.13 or newer
  • install library Keyboard 1.0.2 or newer
  • install library MIDI Library 5.0.2 or newer
  • install library USB-MIDI 1.1.2 or newer
• install Tampermonkey extension in Chrome/Firefox/Edge/Opera/Safari
• import OVLP.user.js into Tampermonkey

Usage

Use the toggle switch to switch between bank 1 and 2 enabling different keystrokes / MIDI messages that the pedal will send via USB to your computer.

• bank 1 is for Youtube / Vimeo (and can be used for other applications that support custom keyboard shortcuts)

  • footswitch Play / Pause
    • short press will toggle between play and pause
    • long press will reset the playback rate and clear the loop
    • sends Shift+Alt+S (Shift+Alt+Q for long press)
  • footswitch Loop
    • 1st time: sets start of the loop
    • 2nd time: sets end of the loop
    • 3rd time: clears loop
    • sends Shift+Alt+W (Shift+Alt+T for long press)
  • footswitch Back
    • short press will jump back 5sec
    • long press will rewind the video
    • sends Shift+Alt+A (Shift+Alt+R for long press)
  • footswitch Fullscreen
    • will toggle between normal screen and full screen
    • sends Shift+Alt+F (Shift+Alt+Z for long press)
  • footswitch Forward
    • will jump forward 5sec
    • sends Shift+Alt+D (Shift+Alt+H for long press)
  • footswitch Speed
    • will toggle between playback rates (100% -> 75% -> 50% -> 35% -> 20% and back again to 100%)
    • sends Shift+Alt+S (Shift+Alt+Q for long press)

• bank 2 is for any other application like your DAW

  • it will send MIDI Program Change (PC) messages on channel 16 that can be assigned to useful functions in your DAW
  • Play / Pause sends 5 (55 for long press)
  • Loop sends 2 (22 for long press)
  • Back sends 4 (44 for long press)
  • Fullscreen sends 3 (33 for long press)
  • Forward sends 6 (66 for long press)
  • Speed sends 1 (11 for long press)
  • if you want to change them...
    • modify the Arduino code and upload it to the Arduino Micro
    • instructions where to modify the code are right at the top of that file
