Hi together! Currently Waldorf sells a Expansion Board for the CME Midikeyboards.  You can find it on german seller Thomann: http://www.thomann.de/de/waldorf_nano_synth_fuer_cme_uf_keyboard.htm 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....
