[sdiy] That Corp transistor arrays

[Christian Bergmiller]

THAT 4305 - RMS level sensor (log) / VCA (exp)
could be used for vocoders, similar to the NE571 approach.
Too bad i already designed and ordered a Vocoder PCB using the NE571.
(the control voltage can't be accessed on the ne571 - it's doable with the 4305)
