[sdiy] TR-727 problem - quick fix?

[mark verbos]

Hi,

I have a TR-727 that has decided to only play the left sound of all  
the pairs of sounds on it. i.e. only the low agogo, only the cabasa  
not the maracas, etc. Is this a common thing that someone has dealt  
with. I am a little confused by where that switch is happening on the  
schematic. My experience with this generation of Roland stuff is that  
it's mostly cracked solder. I'm gonna try touching up the solder on  
the connectors right now....

Thanks in advance,



Mark
