All about the Roland Jupiter-series

Great idea, I'll try to get some "cheat sheets"made for the board. 

Another cool effect was to turn off one of the oscillators, use the 
highpass filter with audible resonance modulated by the LFO 
random, and then use the oscillator mixer to "fade in" and out the 
active oscillator. It sounds really cool. I am going to have fun. 
BTW I have a question. Upon research I've noticed that some 
JP-6's have a louder resonant filter when driven into feedback 
than others. Mine could be slightly louder, I think. Is there a trim 
pot on the filter board inside that can be adjusted to make the 
resonance feedback louder when cranked up? Maybe this 
adjustment is mentioned already by someone online..
