i was wondering if it would be possible to use those oooooldschool windshield-wiper-lookalike thingies to display midi activity (one for in, one for out)
i am asking this because i have a nice tabletop amplifier case that would be perfect for a midibox64, and it already has those things (what are they called???) in it.
is it possible? after all, they are analogue unlike a LED.
it should work with the same circuit which is used for LED indicators (LTC module). Maybe you’ve to change the 10 uF caps to a 1 uF or lower for best visual results…
The LTC sends pulses on every MIDI event, than more pulses over time, than higher the deflection of the needle (such a measure behaves like an integrator)
