Creo que tienes que cambiar el parametro Program Change de la MPc y dejarlo a zero como comenta el amigo...
En la MPC1000 con JJ OS esta a la derecha de la pantalla MAIN y pone PC, si cambias ese parametro, vas cambiando de preset en la maquina que controles, supongo que el problema te vendra de ahi.
Puede que necesites instalarle el JJ OS a la 2500 tambien, sera mas estable i ganaras algunas funciones extras...
