Let's hope the SEM filter shows up first, so I can order my second batch of
modules!! If someone really wants to develop a Roland filter clone, I have
a couple of spare IR3109 chips. I could lend them one so that they could
reverse engineer it.

I'd much rather see a Juno 60 chorus "clone". Imho, that was its best
feature. Unfortunately, BBD chips are getting scarce.

The filter in the Juno 60 is the same as the SH101 and MC202. The TB-303
is completely different.

That's a very good question!! My SH-101 schematics are very hard to read.
If anyone has a better copy of the LFO section I want to see it. I tried
to do the external clock mod to the LFO, but unfortunately the Nova Mod
documentation is sheer and utter crap. Almost all of the other mods it
contains were cooked up eight years ago by Todd Sines, myself, and others,
but a synced LFO would be great!! As I'm sure you've already noticed, the
S&H is already synced to an external clock.

Anyway, from what I can tell, the "random" on an SH101 does not use a true
sample & hold circuit, ie. it doesn't seem to sample noise voltages with a
cap. It uses a "random" output from the DA converter, but I don't know how
random these voltages are. It is quite possible that they are quantized to
the nearest semitone.

Yes, if it were 1976, MOTM would be Mercedes, and Doepfer would be AMC :)
There are a number of Kenton products that convert MIDI clock to
arpeggiator clock. I also use the 707 or 909 with a Garfield Dr. Click.
Still, I would love a pulse divider module with the ability to do odd
divisions. I was going to put it next to my SEM filter ;)

I have no idea about the uLFO. I spent quite a bit a time suggesting
various configurations, but I haven't heard the results. As it stands now,
the 300, 310, and 320 are all fine clock sources.

They are a psy-trance band that are quite fond of using video game noises.
