Render Delay Tap Tempo

[tape]

Apologies if i've misunderstood and asked in the wrong place, I dont really understand the software or terminology fully.
I'd like the option to tap a button somewhere in obs, in time with music, and have that set the ms delay time in the render delay filter, possibly with time divisions of beat, 1/2 beat, 1/4 beat etc. like a tap tempo would in music software.
I use OBS virtual camera for video feedback loop art,
Part of that relies on adding a render delay filter to sync the feedback loop to music.
I can achieve this manually by looking up the tempo of the music thats playing and putting it through a bpm to ms converter, but it makes the process not viable for live adaptation to tempo changes.

I understand this is a misuse of the software so any advice would be appreciated

It's a little bit hacky, but I wonder if the Advanced Scene Switcher can read a wall clock and subtract two readings? I know it can modify filter values, and you can have a docked button to trigger it manually.

You might ask over there and see if it does:

If it does, then I would have:

• Variables:
  • Current Time
  • Previous Time
  • Interval
• Macros:
  • Timeout (prevents a super long delay when you first hit the button)
    • Conditions:
      • Single-shot Timer
    • Actions:
      • Disable Tempo.Action_#6 (setting the filter delay)
  • Tempo
    • Conditions:
      • Docked button
    • Actions:
      1. Current Time = wall clock
      2. Reset/start Timeout.Timer
      3. Interval = Current Time - Previous Time
      4. Previous Time = Current Time
      5. Massage Interval into the correct format
      6. Filter Delay = Interval
      7. Enable Tempo.Action_#6 (setting the filter delay)
