Paul,
You're missing just a few modules. I think Dave V. had the count closer with about
22. Here's some that I can think of off the top of my head:
901 oscillator (predates the 921 and sounds different but less stable and no PWM or
sync)
901A oscillator driver
901B oscillator
9xx Envelope follower
904C Filter Coupler (used with 904A and B to kinda do a bandpass)
There were a few versions of the 914 filter bank, some with more bands
9xx Bode Frequency shifter
There were also a few attenuator panels but I would count them the same as the CP
mixer/CV panels.
9xx four channel mixer (a large module)
The sample and hold was a separate box. There were also some custom additions like
ring modulators, etc. but I don't think they made those as modules.
We also can't forget the other controllers besides the S&H, the keyboards, the
ribbon controllers, the X-Y controller and the drum controller.
We certainly do have it better these days with a larger selection of modules and
capabilities!
