Modules 902 ,903A,904 (a/b/c),921 (a/b),923,911 ,911A ,912, 914 ,928 ,984, 994, 995 Moog Synthesizer / Moog Modular / Moog Synth – there are a lot of Clones and  re-makes out there  – this is about the functional things. the original modules are NOT shown here. you can check it like this:

1) the metal sides are different, the mechanical works are also a bit different

2) this system has no Jones Plugs as the original has, others use 6mm Jacks since no1 really wants “Jones Plugs” (they are not common and have never been used here in europe for something, thats why I’d give the advice to use more common formats on systems that are not original or moog like – like this..

this moog modular system is re-packaged. the vinyl cabinets of the system 10 and system 15 normally have to rows
of moog standard modules – the bottom row is for the CP modules (mixing the signals and audio!)
here I got completely new cabinets and re-installed the moog modules with normal size and extra power adapter (which is also not original!) to make room for more modules and the matrix mixer in the mid cabinet.
the sequencer and 2 VCOs and the multimode filter on the left (3 knobs can be seen) are all modules which are very well with the moog modules.. the sound is comparable to me ears (OSCs) and the layout sometimes is smaller and better (compared to my driver – VCO triplet)

die module die es hier gibt / modules to find here:
902 ,903A,904 (a/b/c),921 (a/b),923,911 ,911A ,912, 914 ,928 ,984, 994, 995 ,
and / und: sine converter, ringmodulator (which is of course not a moog module!), inverter / buffer
what is what / was ist was:
902 VCA lin/exp.
903A white & pink noise,
904 (a/b/c) filter (lpf,coupler, hpf),
921 (a/b) VCO (driver/osc),
there is also the 921, that is driver and osc in one but no weak sync!
923 noise pink&white and non-CVable lpf and hpf
911 env gen. ADSR s-trigger (see it opened),
911A trigger delay,
912 envelope follower,
914 fixed filter bank 12 bands plus hpf and lpf (here with ind. out for every band makes a nice drum machine with a sequencer),
928 sample & hold and glide,
960 sequencer
984 matrix mixer (!)
994 multiples jack (one with knob to have 8 as a group, normally groups of 4 (2x),
995 attenuators (3x)

the sequencer – moog 960 (there is a clone from available, this is the only original in this list)
moog 960 sequencer

fixed filter bank, 914 modified with ind. outs for every single freq-band. THIS is imo one of the nicest sounding modules.. there are not many standalone fixed filter banks out there (exept the one from snd) , attenuators (you need those to set the real mod amount to any mod destination) 995, Sample and Hold/gilde 928, envelope follower 912

the matrix mixer: you got 4 ins, 4 outs and simple filters (trebble / bass), so you can mix some OSC signals together and route it everywhere you like to..

the filters 904 lowpass, and highpass on the right (hpf has no resonance! no moog ever had this by the way)
the coupler is a very nice device: you can control both filters with this and use the filter as one bpf with modable bandwidth and center freq. also it is possible to use it as notch (this is one of the first USABLE notches!! because bandwidth and center can be adjusted.)
this is the 904A lpf, the 904B hpf – the coupler is the 904c it’s very close to that of the new voyager but, hmm.. your ears decide.. the 2 jacks block the way to see the range switch (hi/low), no reso as said.

this is the heart: the driver and oscillators 921 A and 921 B
via driver all oscs follow the frequency of the master vco! good for minimoog-chords, bad for fm: so you need another driver.. because trhe range is set on the master driver and the oscillators got an offset to the driver!
– the inverter buffer is for amping and offseting the signals (boost and set it’s symmetry)

this is pink and white noise 903A, but with the 923 you have a LPF and HPF that cannot be modulated or voltage controlled
but it’s nice to have specially filtered noise sections or pre-filter some VCOs.. if you turn it: it really sounds good!!.. so this is a good thing if you want to save CV-able filters.. or the fixed filter bank

the ring modulator, a trigger delay (use this for having one env. starting XX secs after another..) 911A, and the multiple jack is just to extend some signals or if you want to have more than one cord on one position..
moog modular synthesizer system trigger delay ring modulator

this can be used to reconvert sine waves into rectangular or saw!! turning the know gives interesting effects on the “edge”, modable! gives some intersting bite!! well, moog themselves did not do this module, so I don’t know really who did the ciruitry, but if you come across one just think if you need those “shaping” kind of convertor or not but don’t think of selling it as a moog. as well as most of those modules shown here, they are here to show how they look like / the tech / function, but imagine them with different metal sides, then ;)

the envelope generator 911 (not a porsche) with s-trig (see the strange jacks) warning: the first 3 knobs are for RATES, the BOTTOM MOST ist the Level – so you need to set sustain here – and the switchable VCA 902 (lin or expo) on the left.

tthis is the 911-like envelope generator opened

here’s the design, how a 911like module can look like.. very accurate, very close , same components as the Moog 911 EG

this one is heavily re-stored.. just one word: watch the pots! they should be like the original.. means – check if its lin or exp ..

this is how it looks like opened, as well – nothing is real – synthetic world..
see the beloved moog “control badge” —> note the quotes ;)

also 1:1 Clone, but some mechnical things different..
here’s the moog 911 module (envelope) l:
Poti 1(das alleinstehende): Nullabgleich – stelle hier die Envelope auf 0 Volt, wenn kein Trigger anliegt.
Poti2: Abgleich Glitch zwischen Ende Decay und Sustain-Level. (Ohne Abgleich gibt es einen deutlichen Sprung zwischen
Decay-Phasen-Ende und Sustain-Level.
Poti3: Null-Abgleich bei S-Trigger. Hier wird also anscheinend sichergestellt, dass die Decay-Phase ebenfalls auf Null zurueckgeht.
Wichtig!! Zum Abgleichen von 1 + 3 sollen alle Regler am Linksanschlag stehen.
Vielleicht ist es ja ein hoher Glitch, der Dich stoert. Einen Trimmer zum Abgleichen der Decay-Phase gibt’s also leider nicht.
Falls der Abgleich nicht ausreicht, muss der Envelope modifiziert werden. (thx to jörg schaaf ..!)

Dieses System ist ein Nachbau eines klassischen Moog Modularsynthesizers der Experten für Synthesizer-Repliken und Restauration von Originalgeräten Nicola (…) und Fabio (…), Padua (Italien, siehe unten). Ergänzende Funktionen, die von Moog nicht vorgesehen waren, bieten einen zusätzlichen klanggestalterischen Aspekt für die aktuelle elektronische Musikproduktion.

specialists for ppg and moog in italy, padua. non commercial, menas theydo not “produce” modules and clones.they restaurate, repair and built moog and moog like machines (clones like the shown system) and ppg systems. but not today since moog was back, so don’t ask them anymore for more, it was a more private thing – just for reference –

fabio and nicola – BKS ( Bass Konzept Studios)
c/o Santi Nicola – Piazzo Fabio

please note – if you got one of their systems don’t sell them as a moog!! important!! they are great, but just to tell.
