Hello.
Ketron has copy protection system since Audya but for her own reasons she doesn't have it (public).
But when someone foreign developer ask for the protection system, the company provides it.
For various reasons, however, there were not many who were interested in development.
Regarding your concern about the chords in the new Real Chord, I have the following to say:
It is something much more different than the old sliced Live Guitar which indeed in most cases did not exceed 4 to 5 different chords so in the case of choosing a chord that did not exist a midi file riff which was trying to fill the void.

The new Real Chord of Ketron It has two exellent new features:
1) Incredible ease of import into the machine.
2) Multi-chord capability.
But let me not expand further because I can't say more that right until the company announces everything.
When everything is announced I will be able to analyze it for you.
Thanks.
