here is a demo of my new casio ctk6200 keyboard with custom piano, song1, dsp and mixer settings.
played by midi chung and recorded with audacity
=> my piano (uses flash player)
you can also connect dsp_chung between lineout and linein of the ctk6200 to add external reverb and decay effect , i have added a "testloop" button to adjust gain to avoid feedback larsen oscillations .
example wiith dsp_chung
