Flimsy data encoder?

My data encoder is very flimsy, jumping up and down in value when turned making it hard to get exact BPM. Not a "precision tool". Also under the Shuffle settings it flips up and down when turned.
Is it just mine?

No mine is jumping too. I have a hard time to dial in the total accent. Sometimes it just goes up but not down anymore.

Any suggestions for a better option?

I heard this is probably because of a "software solution only" debouncing it...making it flimsy.

Same with my encoder, it's not that bad but definitely goes the wrong way on some occasions

Often people use a pair of small film or ceramic caps Between the encoder terminals to filter the true pulses and disregard any noise. Values under 1nF are prefered.


Here is a link to it on a synth.

Clever! :-) Somebody should give it a try on the Nava.

And somebody did! :mrgreen:

I had the same issues but now, no more jumping back and forth!

Actually Bourns are mentioning this in their technical documents: http://www.bourns.com/docs/technical-do ... f?sfvrsn=4

As I had a bunch of 1000pF left over, I soldered 2 of them "Manhattan style" to the encoder pins. Common ground.
I did not add the two 10K resistors as per above. Anyway R692 and R693 are already part of the circuit as well. It works perfect without the other two.
