Based on what you currently do with your ROLAND and the specs. you are looking for (SWELL), the XD3 would be best for you (esp. if you don't care too much about playing back Wave and MP3 files). The KETRON XD3 has the FULL arranger capabilities including SWELL (control of only RIGHT volume from volume pedal), Creating Styles from scratch) ... etc which the MIDIJAY currently doesn't have. We are working on OS3.0 soon to be released with more features, but I would strongly recommend the XD3 for you if you still want to use the MIDI Accordion as the controller.

Thanks,

AJ
