There is now a modification available at Keysound when using a Roland PK9pedalboard with the Korg PA3x, PA900, or PA600 keyboards. We connect a midi cable to control the note information and a new midi preset is made in the Korg keyboard. We then wire a stereo socket to the side of the swell pedal and connect it to the Korg using a stereo jack lead. The pedal can then be calibrated within the 'Controllers' section of the keyboard and must then be saved in the 'Global' settings.
It's an absolute dream to play, call us for more information or to use other pedals.
