ABOUT Dieter Doepfers Modular System offers a laaarge variety of modules, even 8bit samplers that allow CV control for position, modules are very different in sound quality.. take a look, there are very interesting ones among them..
ABOUT Doepfer hat wohl das umfangreichste Modulsortiment für 3.5er-Systeme. Die Klangmöglichkeiten sind sehr unterschiedlich, daher ist gutes Aussuchen sinnvoll.
DETAILS well, need I say much about doepfer modulars? in germany he began with CEM chip based synths, C64 control and lots more.. very interesting controllers like midi glove, theremin to sensor keyboards.. well , need I say something on doepfer? the A100 Modular system has the most modules to offer, some are great, others are "cheap" but ok.. more on this soon.. here in germany it is the cheapest system available and: I do not know about a system that has more modules available than doepfer! here you can see 2 theremin antennas and the trautonium subharmonic oscillator. the original trautonium was a special instrument played by oskar sala (remember "birds" from mister hitchcock?? that sound came from a trautonium..) a german product. very interesting modules: the morph filter from the oberheim xpander can morph through a lot of filter types , can be controlled via CV! the sampler: is not really just a sampler, its more a wavetable to be scnned through by CV! very cool for us warpers and buffer overload lovers of strange abstract music! the extreme filter: well, it's a kind of ms20 filter.. to my ears a bit more evil ;) sheppard generator: if you have a big system, try the permanent gilssando or permanent infinite openig of a filter.. you need at leat 4 filters, VCOs etc for it.. the older modules do not sound that cool like the moog one , but the newer ones and all vactrol based modules are really interesting and much better in sound compared to the first VCOs and VCFs of the early doepfer A100 series.. Again a Doepfer System, Doepfer offers a lot of different modules, imo it is a largest variety i know of.. there are also very special modules available like the xpander morphing filter or a sheppard generator to make "neverending permanent effects".. means: it sounds like an opening filter but it will never sound like: it is opened to the max.. check KH Stockhausen "permanent glissando", maybe he also used a sheppard generator..
DETAILS was soll man zu Doepfer sagen? Er war schon früh CEM Chip und Modularbastler, schon zu C64-Zeiten und gehört zur deutschen Synthesizerszene seit dings.. (ewig halt!) es gab interessante controller vom midi-handschuh bis zum theremin und dem sensorkeyboard.
SOUND everything, its modular and very flexible..
SOUND alles! modular und flexibel..
VERSION here are some recommendations.. to my ears the new VACTROL based modules are cool, the SSM Filter (prophet type sound) sounds good. the morphing filter is something like a programmable oberheim xpander module, it sounds not as broad as the original but it is much more flexible since there are lots of filter modes in it which can be stepped through (and preprogrammed) step triggers can be fed in externally, the modulation can be put on reso, cutoff, morph etc.. so it is a very flexible good sounding module. the xtreme filter is very hard and evil, it is said it models the ms20 filter, but to my ears it does not replace the ms20, it (my model at least) sounds much more nasty and more extreme, so it is good for all who still search for NASTY sounds.. the older VCOs: sorry, I really don't like that sounds, the FM is bad and far from "nice".. maybe there are ppl who like it.. it is the absolute opposition to wiard, serge or moog.. moog? there is a moog filter avvailable, it sounds thin when resonance is turned up and that is no moog behaviour, I assume those ransistors are not hand selected and do not match that much, it does not even sound tb303'ish (in fact the 303 filter is also a bad moog clone, but a COOL one..) sorry, this is one of the worst modules in the system.. to come back to the positive things: there are very special modules ,that do not have to compete to so many others, eg the WASP filter (it is digital ,such as the original EDP filter, very british) and pan and vector control VCAs (4x) are there.. the envelopes are all good and FAST, doepfer also offers stacked and kind of multisegments: a quad AD ENV with comparators that switch over to the next AD stage when a signal is detected to run the same direction" so it is like coupling 4 ADs to one! also usable as LFOs. same for a quad ADSR envelopes.. one of the coolest modules is the sampler (incl midi), which can sample 2 samples and scen through it and play segments out of the samples. the "scan" is a bit like a wavetable and can be CV controlled.. very cool for nu skool style of sounds.. adds very well into old fashioned modular synths..

DOEPFER known or written as Döpfer or Dieter Doepfer Musikelektronik

Dieter Doepfer has a long History and I still have a catalogue with C64 based CEM/Curtis Synthesizers (8bit Computers), now he's known for one of the larges amount of modules and even the euro rack is called doepfer rack.

Official Intl. Site :

DER deutsche Modularsystem-Hersteller begann als Importeur und Bastler auf Basis von CEM / Curtis Chips und C64 bzw. Apple II, heute vermutlich Anbieter der größten Modularsynthesizer-Modulpalette.
Auch bekannt für nahe Zusammenarbeit mit Kraftwerk.
