No it hasn't. My best guess is that it will be part of the 3.0 firmware upgrade, leveraging RAM that has up to now been reserved for/ available to other time-domain effects (delays, etc.) The upshot, by my best guess: looping will take place in the KPA itself, controlled by the Remote, potentially controllable via the footswitch inputs (or other MIDI controllers if Kemper decides to make the necessary information available.) Also, probably a pretty short loop length, since I can't imagine they've had gigs and gigs of RAM just languishing for the past 2 years. (If they did, they would have teased the plans for a looper for much sooner.)Another possibility, which someone raised earlier, is that the USB memory stick will be used for this purpose, but I personally doubt that interface is fast enough.
Common - :
Oversampling x8
24bit = 3 bytes
33.554.432 / (44100*3*8)=33554432 /1058400=less then 31 seconds
What loop or phrase will took 20seconds of oversampled data?
What do you want to loop? whole song?:D
If you want to add something to the recorded loop - there is no need for additional RAM .
You do that with read x-memory location , read input audio register, add this two - put to the x -ram location / per every sample data
I've told you that Kemper has 32 MB of RAM - you can see this in debug mode:)
