MOTM

My 420 is now alive and it worked perfectly first time out. So, here are
my observations:

When I read this, I thought, "now Todd, no need to swear". However, now
that I have mine hooked up and running I have to say, "SH*T... Somebody
screw my head back on". There IS indeed absolutely a NEED to swear when
you crank this puppy to extremes. Congratulations Paul ! You have made one
NASTY filter here. Forget smooth and forget pretty. This is one
butt-ugly, huge-gonad, screamin' filter.

Whew, I just had to get that out !! Now, some more objective observations:

I love the reversing attenuator. It's great to go from positive to
negative modulation with the twist of a knob instead of re-patching or
inserting an invertor (we don't have just yet).

The mixer is a GREAT feature that doubles the value of this module in my
opinion as I will almost always have two or three inputs. So, the mixer
here keeps me from dedicating some aux mixer to the frequent need at the
input of the filter.

My V/Oct tracking worked very well over about 4 octaves. However, it would
not make a good oscillator (not that it is supposed to be) as it seemed
just a bit off in the middle of the range when both ends were zero beat OK
against the oscillator. Of course, up until now, I never even knew that
the oscillation of a filter could be calibrated AT ALL, much less be
accurate like this. Wow!! I did not get anal and try to soft sync the osc
and filter oscillation together, BUT, mine was close enough I bet it would
have worked over the 4 octaves I tried.

One of my favorite filter effects is in my MicroMoog where the filter can
actually be modulated by the oscillator. I tried this on the 420 and got
some VERY interesting results, but not the same as the Moog. I am looking
forward to the day that the MOTM Moog ladder filter is a reality too and am
hoping it has similar FM capabilities. Any tips on the best way to
modulate a filter with audio for interesting results?

Now, I am going to try some external processing and report on that tomorrow
night.

Let's here from you guys that are more modular savy and tell me more ways
to plug this thing up to make more good noises.

Remember that any audio or control voltage signal can modulate a filter. Try
the output of a nasty cross mod from the MOTM-120. Try audio signals like
drum machines and speech samples. Try a ring modulator output. Make the VCF
oscillate, split the output, and feed part of the output back into a FM
input.

I too have a Micromoog, & found that running the audio out of it into the
420 & back again to
be very interesting. I n the little time I've messed w/ this setup I've
gotten good distorted bass,
good handclaps, & screaming nastiness of many varieties. Also, as you might
expect,
small variations in knob settings can make huge differences w/ this
configuration.

Have fun

Thanks Dave, err... Moe and Tom for some great tips.

Back to some patching
