The problem for a comparison is, that there is no "Doepfer Vocoder", but
some modules, that provide vocoder functions for the complete modular
system. If you include other modules (e.g. Highpassfilter for better
unvoiced signal handling; Mixers, ExtInput, VCA, Inverter for
compression;...) and if you include the knowhow how to use them for
vocoder orientated usage, you will get a vocoder which is beating the
most of the vintage vocoders. If you only look at the 129x modules, some
vintage devices may look better.
