" Transpose EFX " [ a.k.a Digital Capo ] ...... latency is really noticeable .... is this a known issue (?)

I'm no expert but I'm sure the KPA doesn't record what your playing, but I maybe wrong

Quote from LH

I'm using the Transpose as well and i too notice the latency.
Nevertheless this feature saves me from bringing a second or third guitar with different tuning to a gig. So i am willing get along with the latency.
I just try to focus on the band.

My understanding of the latency is this:
The Kemper records your playing and then gives it back with a different speed. So when you need to have a full-tone up, it will just give you back the recording at higher speed. This will result in a higher pitch.
Can anyone confirm or correct this?

No - basically it several pitch shift algorithms. Most popular use delay line and play it at different speed. But to have nice effect you have to have delay time longer then the length of the wave that you are playing.

Thanks Damian!

I thought i read this somewhere here on the forum but i can't find the post. So maybe i got different things messed up

Found the solution in another post:

Transpose in Stomp X = big lag
Transpose in Stomp A = NO lag

Just tried this and it works!

I haven't tried it in Slot X and always used it in Stomp A, but even there i get latency.

Its no matter how fast will be the DSP - still you have to capture one full entire period of the wave you want to transpose to the buffer.

Of course, you're right, Damian. I just figured faster DSP ability might bring the latency down a little further.

It's a battle that can't be won, 'though, as you suggested.

Didn't think I was experiencing latency -- I had it in stomps all along (you want your tuning changed before it hits the rest of the signal chain/processing in most circumstances...would have thought this would have been obvious...)

Under some conditions, there IS a big lag, way more than 20 ms. I confirm.

Which condititons exactly?

yes I would be curious about conditions as well, as I was just about to try this feature for the first time

I don't know exactly, deep and better investigation is required, but I confirm that in a randomly choosed rig the big lag is present if the Transpose is set in the stomp X and not present if the Transpose is set in the stomp A. So we need to discover what make the difference.

If this behaviour is coming from some bug, the conditions could be anything external factor, not the rig itself. A laggy rig on my unit could be a good sounding rig on another unit.
To make some comparison, I must post a laggy rig and a recording of his sound, so that another user can test it and hear the effective entity of the lag.

Just finally set this up today to tune to D. I put it in the A spot, and did not notice ant distracting latency. I've been playing guitar synths for 30yrs and I understand latency

You should open a support ticket concerning this.

Agree with Ingolf, you should open a support ticket. I used it tuned to D at practice in the band last night for the 1st time and Me and no one else noticed any latency.

There is definately latency and the sound also changes. Try a clean sound and bend a note. You will hear it.
