tap tempo led for dd-5

[ninjadave7]

has anyone ever done this before?  making an external tap tempo switch is cake, but i don't know how to (or if someone could) add an led that blinks with the tempo.  any ideas?

The tempo is set inside the microcontroller in software in the DD-5.  It's not exposed outside the chip in any form that you could use to drive a LED circuit.

However here's one idea that may get you near what you want.  Grab the echo signal going into the level knob, and use that to provide a tempo signal through a transistor to an LED.  Effectively it would be showing the delayed audio signal on the LED but without the dry signal and before the echo is reduced through the effect level knob.  However If you have the repeats level high, the echo signal will get messy with all the repeats layered on top of one another, and this approach will not work well.

thanks, that answers that one!
