Amazing! Huge difference! I havent found any sluggishness yet, everything is very responsive, and after setting the sysex enable to +2 on the M6r, I was able to send negative values no problem from either my ipad or computer - 

  One question, is there going to be any way to get modulation parameters up and running on this Can a larger Eprom be used for more code Sorry, newbie question Im sure. I have no idea if thats impossible....

  Anyways, highly recommended
