Adding tap-tempo to Deluxe Memory Man... help!

[benallison]

Ok!

Cusack has a killer tap-tempo board that was designed to go into Zvex effects that don't have tap.

Amazing.

So, is anyone familiar with this board? What's to prevent one from dropping this into a Deluxe Memory Man, or, whipping up a similar tap tempo mod?

I figure that a tap-tempo circuit needs to do the following:

1) measure milliseconds between taps
2) translate this number to a corresponding amount of ohms

I understand part two would be pedal dependent, as a certain pot value in a certain pedal will determine a certain amount of milliseconds... but surely this is not an impossible task...

Help!

this has been discussed a lot. Do a search on this board.

It's been discussed a lot. I'm asking if an actual circuit/walkthrough/recipe exists.

I contact Cusack about that board.
But he is only allowed to sell that board to Zvex seek trem and seek wah users.

It sure is a possibility to add Tap Tempo to the DMM, but the short delay time is a factor here.
At my fastest tap speed i can tap in 270ms (quarter notes). Now you can do subdivisions etc.

The tap tempo circuit has to measure the tempo between taps in ms, and convert that to a clock signal for the delay chips in the DMM.
But that's the hard thing, tweaking the clock time so you get out what you tap.

Iirc the cusack mod is used to drive a LFO.
From the discussions I learned that driving a clock is a whole different beasty.

The "easy way" really is to get a micro controller and program it to do exactly what you need it to do.

However, I do believe it's possible to get halfway decent results with analog circuitry, but that way is reserved for really smart people, really diligent people, people with way too much time on their hands, and/or really crazy people.

Well, Cusack is making a Tap tempo LFO for his tap a whirl and tap a phase sequencer is a clock generator.
Giving a pulse every time the timer overflows on the desired tempo say 500ms.

And i think this is not to do with analog circuitry. Digital is the way to go.
