Hello !! When I record music, LED's or other signal level indicators are very useful by 
analogue as well as digital. Meanwhile it is said Analogue Modular Synthesizers such as 
"MOOG Systems" and "A-100" are originally instruments without them.This oscilloscope 
module issue is whether a musician is able to concentrate his(her) attention upon his
(her) works or not. Is the oscilloscope module voluntarily one of the requirements of "A-
100" by DOEPFER ? ciao !!
