Elektron Musical Instruments

this is my first serious problem ive encountered with my sid....it wont
respond to midi channel 2 which is what channel its on. when i hit a
key...the midi led lights up and i can hear a change in the noise..but no
sound. it works fine if i switch channels....i dont really understand...of
course ive already reset everything and reinstalled the latest OS. any help
would be greatly appreciated...i really dont want to hafta go through and
change around alllll my instruments to different midi configurations...as i
am using all 32 channels on my mpc :-) thanx
