Tap button blinking irregularly

I'm so glad I've found this thread. Since getting my Remote yesterday I was really doubting my own abilities to tap in time

My guess is that the part of the os that updates led outputs is a low priority task and is updated occasionally compared to the serious/audio processing that obviously needs to be priority. Same with the screen updates and remote visual-feedback, maybe as the CPU cycles through its cycles the visuals-components only get processed every X number of cycles, which would explain why faster tempos appear more irregular.
I agree it's a bit annoying but if it's in order to deliver a better audio performance then I accept it for that.

This is really annoying. Hope it's fixed soon.

Any news? It's been a while now and this is really annoying and useless on both head and remote

Just experienced this today. Had a plan to set tempos for all performances and use the tap LED's as guidance when starting songs. Guess I won't for now. Will file a bug report on it.

Just been discussing similar:
tap tempo button reliability
Still an ongoing issue that im confident the K-team will sort.

Confident and confident... :). They are generally great but this was reported almost two years ago.

The tempo still works though. I was thinking maybe I'm too damn high on this Kemper. What a relief.

More than another 2 years later I have to push this up again. Its super annoying. And I actually need the tap as a metronome, because I have a song with a delay which has to be in time and I start alone on guitar.

I have to get out a metronome now and watch it before the song and I think that's embarrassing for Kemper.

Has there even been a comment on this issue from the Kemper guys yet?

What did they say?

musicmad · February 28, 2020 at 1:45 PM

Hehe it's been 2 years. Don't remember.

alexburnsred · February 28, 2020 at 2:44 PM

maybe Burkhard can say something?

Seems like this thread is around five years old..Has it been solved in any ways??

(I need to count in all the songs for a duo and hoped i could use the tempo light as guide instead of pulling out a metronome.)

Not solved. And that is a great use case.

I started a new thread and hope Kemper will see it:-)

Same issue Here, I need to use tap tempo as a metronome to start songs...
2 more years have passed....

I have no technical knowledge, and this is just a wild a$$ guess. Could it be a bandwidth issue due to other communications over the CAT5 interface having priority, and thus the tempo signal - which has to be sent, continuously, from the profiler - gets interrupted to allow for more instantaneous responses for other functions?

I have owned my Kemper since the beginning. I received the foot controller very early in the first batch. At that time, the light worked as expected.

Simultaneously, there was a big push for instantaneous rig changes within a performance. In retrospect, it seems that the synchronization of the tap tempo light was a casualty of instant switching.

If the forgoing is accurate, we may never get the tempo light fixed with the current hardware.

lbieber · August 28, 2023 at 6:36 PM

I notice that the tap LED is closer to accurate at slower tempos which aligns with Dlaut's comments.

I think etherCAT might provide a solution to this issue?

Dlaut · August 28, 2023 at 7:12 PM

I may have misspoken a bit. I don't believe that it's the bandwidth of of cable itself. CAT5 has a bandwidth of 10/100 Mbps @100 MHZ. I *think* that the cable was just a convenient, readily available interconnection method.

I believe that the timing issue is hardware related. As far sighted as CK was, I think the clamor for, and programming consequences of instant switching was unforseen. Having said that, I would far rather have instant switching....but, both would be nice.

Just out of curiosity, does the Kemper Stage tempo light work correctly? If so, my hardware theory may be supported.
