Let me first say I am very pleased with the KPA. The way it looks (not too weird for me), the easy user interface and not the least the sound.
But I think it is a big flaw that it is sold without a lot of functions prepared in the hardware but not working in the software.
A piece of modeller in this price range should of course have a computer interface and ann editor and not use USB memory stick to transfer files and backups.
It should not be necessary to boot the KPA everytime you transfer new rigs!
The Perform mode is still not working and not the network connector either.
Undo/redo is not working.
A lot of these functions is described on the Kemper homepage and also in the user manual as if they were already implemented!
On top of all this the firmwares has a lot of bugs and even if they are BETA versions the last public release was from beginning of this year despite all the lacking features.
It says on this "Feature requests" "We are known for frequent feature upgrades"
All together this is very close to not at all acceptable for a "professional modeler" that costs around 1444 EUR.
