After the remote there will be some future evolution of the KPA itself? There will be some next step to the KPA algorithm ? Or the project is done and finished?
I don't have in mind the features like fx or some tweaks.
Is there some future researches going on with KPA patent?

What is on my mind is for example the alien sounds can be burst patterns to take some transient analysis from the amp.
Or can be burst patterns to take a compression characteristic of an amp over a time.
Now we have some hardcoded (bias, compression and sag) algorithm that are independent(or partially independent) of the real amp.

Just wondering if there is some future developments:)

Where did you get 2.8.1. ?
I want it too:)

From pdf is only 2.8.0.10

Can you connect the KPA to the some audio interface with SPDIF ? Then you can check that this is D/A(or post d/a op-amp problem) or some software issue.

Maybe - or maybe it was a joke (only one user has this issue and no one can reproduce this issue )- but I tell you what I think it may be constructed from what i know. This is only my opinion.

If I record a loop with one rig (sound) I would be able to add another loop or play along with a different rig without effecting the original, correct?
How about saving the loop? Is this possible?

1. I think yes - your be able to change your rig without affecting the loop sound.

2. I don't think your be able to save the loop .
The loop is stored in RAM memory - so if you switch you KPA off it will be deleted. Flash memory in KPA is too low to store your loop.
But it's nice feature request to store your loop on the USB stick:)
Especially if you can store it in wav file format to play or cut it in PC.
Another problem is how KPA will ask for play loop from your USB stick/ or record it .

This is difficulty problem because :
- If you play with dynamic / low compressed rigs - some notes played hard may be too loud or may find that after normalization low volume notes are at very low volumes

How do you want to normalize? Normalization is taking some value of loudness (dB dbA ) from some time period. How long the time period must be?

Compare it to watching a movie with commercials:) they both has different dynamics - and commercials are always louder then the movie - even when the dB meter showing the same.

It will always depend how you are play (low or high dynamics)/ or rigs with you are play (distorted or clean).

If you want to normalize - then use compression and limiter as last FX.
Limiter in KPA? That will be good feature request:)

Another way is this :
1. to put the "normalize" option to the rig menu - with some dB frequency weights and as parameter will be the reference loudness over the spectrum
2. if you hit the normalize in the rig menu the KPA - you have to play your song as usual for some time(?)
3. the KPA will analyze the spectrum with weights over the time and add a correction to the desired loudness level.
4. you have to store the rig.

KPA uses a impulse power supply - so it can convert any voltage from 110 to 240 VAC to the stabilized DC value.

Make sure that in system menu on page 4 you have set:
Pedal 1 to Expression(Type 1 or Type 2 ) and on 1: is showing Wah Wah

From EP-3 website:
Supplied Cable: 6.5’ ¼” TRS - TRS

should be ok.

Quote from heldal

The looper should, at least IMHO, be controllable via MIDI too.

It should but it isn't - at least that I know from the official news and sources.

Quote from Papoos

Is there the looper in the new firmware ? I am not sure i have well understood....

Yes - but only for remote owners.

I don't want to create another thread so if you interested - this is my preset for church organ using 2xpitch shifters:) (fw 2.8 using some ac profile)

1. It may be a problem - because the KPA need to know that you are a browsing internal rigs or RE rigs.
2. The RE rigs may changed over a small time period.

But +1

Quote from Raoul23

monitor out is only jack not XLR do you mean TRS ?

Sorry - i mean on main outputs use XLR My mistake:)( corrected)
KPA on monitor output have only TS connector:
"Monitor Output:

¼ inch TS unbalanced with ground lift max. output level: +16dBu"

TRS is for balanced or stereo signal.

TS stands for tip-sleeve and TRS stands for tip-ring-sleeve.

On main outputs use XLR balanced if you can - to avoid 50 Hz AC hum - but your In ears have to have balanced inputs. TS are unbalanced.

Use standard symmetrical XLR signal cables on output.
Or specify what hardware do you want to connect to the KPA and what type of inputs are in this hardware.

Quote from Amaze-B

No, the noise gate does not affect this hiss/hum at all. The noise gate works, but I tested this with 1 noise gate and then eventually added 3 more noise gates in the other stomp sections. It didn't matter if I had 4 all on, it had the same effect of just 1 noise gate. This hiss does seem like it could be as a result of EM noise. I will try again later today - it could be because my KPA is close to my computer.

Noise Gate is only cutting a signal out bellow threshold - so if you turn off the noise gate you should hear the hiss all the time. And if you unther the tereshold level the hiss is passing withe guitar signal. Noise gate is not the same as noise reduction .
You have KPA close to the PC - turn off PC and monitor and see if that helped.
What kind of pickups do you have in guitar?

Stay cool - is more than a month to straighten things

It is one of the most basic effects in history of guitar FX but I cannot simulate it in KPA. I have tried with noise gate and compressor but i failed.
it's not very cpu demanding - just put volume to 0 when signal reaches the threshold level - and use some slow attack time curve.
Or even better - to put this options to Lead booster or Pure Booster fx's.

You can try to go to the system menu with USB connected and hold system button for 4 seconds to debug mode.
Navigate to the page with the list - there will be USB Stick Connected at first position - set is to marked.
Then do to the page where is displayed "MAINTENANCE PAGE"
hit right most soft button "USB Update"
there will be a list with avaliable kaos.bin updates - select one and hit update soft button.

or try" Burn FW Image".
Also please try to format usb stick on windows in FAT32 format.

I have 2.8 FW and tried revert it to 2.7 and back without a problem.

I have found that in FW 2.8 on debug mode in system menu there is parameter USB MIDI and Ext.MIDI and you can mark this as on (V):) So maybe in 3.0 official FW there will be USB MIDI support:)

EDIT: ups - mirekgr10 alredy posted this:) sorry for doubled info:)
