"The only difference in the latest ROM that I am aware of is that a reset command is not sent from the midi out when the stop or rewind buttons are pressed on the RM. This is helpful if you are using external midi gear but can also be avoided by having the voice of the channel the outboard gear is on set to anything except "phrase"."
Sabe alguien como se hace lo de la última parte ?
Saludos !
