just was in a music store recently
played a rack version of the voyager
(the shop employee announced the dimmable light as the most remarkable feature )
turned off the oscilators ( and the noise)
turned on the headphone 10 o clock
played a note
heard a remarkable hiss
i think without actually sitting around a voyager pointing out the hisses and noises and the settings an obvious discussion seems impossible
some seem to bother some not
i think the instrument would be nicer if the hiss it wasnt there
for most sounds it doesnt even matter
