MOTM

hi,

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.

thanks for your feedback!

gregory!
