Das Thema IIIC haben wir längst überwunden.
Wir sind beim Model 15 angekommen und vergleichen gerade Komponenten.
Momentan sind wir bei den 921A/B-Oszillatoren.
@Serge: Im Moog-Forum habe ich diese Aussage gefunden:

Der wesentliche Auszug 1:
...>>> WHat im not quite sure about though is what exactly AC and DC modulation is.
Here is my assumption based on my electronics background. The AC MOD input will block any DC component that the modulating wave is riding on. The DC MOD input will not. Say, for example, the modulation source generates a 2 volt peak-to-peak LFO sine wave that's centered on +3 volts. That means the sine wave swings from a maximum of +4 to a minimum of +2. If you connect such a wave to the AC MOD input, the DC (direct current)component (+3) will be blocked. Only the AC (alternating current) component is passed. Thus, what gets sent to the destination is a 2 volt peak-to-peak sine wave that is centered on 0 volts and swings from a maximum of +1 to a minimum of -1. The DC MOD input will not block the DC component. In the end, the choice of inputs determines whether the osc frequency swings above and below C4, or above and below C6.
Of course there's also the possibility that the AC and DC inputs are mixed (like a CV mixer). That means you could apply a fixed voltage to the DC input, and it would serve as an offset for the modulating signal applied to the AC input.
Auszug 2 von Kevin Lightner als Reaktion auf Auszug 1:
Possibly I'm misinterpreting you, but in order to use a 921B, you need a 921A.
They must be paired together.
Any tracking CV must go to the 921A.
The 921B by itself won't work as a standalone tracking oscillator.
I don't understand the wave output thing mentioned.
Zitat Ende.
Für mich bedeutet das, dass die Moog 921B nicht ohne Moog 921A tonal verwendbar sind.
Also ein weiterer Unterschied zu den COTK C921B-Oszillatoren, jedenfalls an den Funktionen
der Ur-Moog-Module bemessen.
Mal schauen, wie es heute ist.
