Hi together!
Currently Waldorf sells a Expansion Board for the CME Midikeyboards. You can find it on german seller Thomann:

It has round a about 1000 Sounds of Waldorf Q (microQ) and it has also limited possibilities to edit the sound in some parameters.
Did anybody (especially you, Thorsten :)) think about to adapt this expander on a midi device? Any ideas?
Bye, Achim....
