Hi all,

Got a hold of a really broken down TMI unit. The unit is up and 
running now but there are still some problems. Everything seems to 
run according the manual but.... the inputs seem to need different 
power. If I have all the pots on max sensitivity then some need 
really hard bang from mr drumstick and some of the inputs could 
handle finger tip. I have not yet measured the pots but my question 
is:

Is there a programable way to put the inputs in a more sensetive 
way? 

I have just repaired a SDS9 powerunit. The unit power up and show no 
problem with the CPU. When I run the autotrigger does then unit run 
the LED but there is no sound from the snare/rim part.
The EEPROMS are ok. Then tom toms are ok. Does anybody have an idea 
of what to check?

Best regards,

Daniel
