MOTM

1/ multiple outputs to mults

While this may not damage the modules, it is certainly not recommended.
The outputs are low impedance stages and are not meant to be
crosscoupled. The mults are for taking a single output to multiple
inputs.

2/ audio to 820 Lag

You can only create a feedback path by feeding the output of a module
back into a stage prior to it in the patching chain.  It sounds like you
haven't done that here.  It might be the result of the Lag responding
only to positive voltage swings, but we need more information here.

3/ 420 astable oscillation

I haven't tried this, but this may be natural since that filter is
designed to have some nonlinear characteristics.  Do you have audio
inputs to the filter?  This can effect the oscillation near the
oscillation trip point.

noticed some 'weird' behaviour:

i'd really like to understand what happens in the following patches:

1/
vco to mult
plus
vcf or lag to mult
equals:
mult output reduced!! 

(almost no sound comes out of mult)

what happens here, electronically seen?
can this damage the modules?

2/ 
shortening audio in of the 820 

while there's cv applied to up/down

gives very strange noises at audio output.

have i created some kind of feedback path with this patch?
can this damage the module? 

3/ self oscillating 420 produces sine with randomly changing 
amplitude? especially noticeable with q pot set to trip point.
