I have a M1 that I purchased new. Due to space constraints, I need to move to a midi controller. What are the differences (functional, storage, processor) between the M1r and the M3r? I already have PCM and memory cards for the M1. The Combinations are of the greatest importance to me. I don't use the sequencer. There is quite a difference in price between the M1r and M3r. Any help would be greatly appreciated!
Thanks!
