Analogue systems

Hi all

Has any of you experience with the aspect of connecting 
modules as a way of playing/performance?

I'm a musician who has performed with analogue electronics 
live. Untill now mostly with my EMS Synthi AKS. Then I added the 
Synapse, a digital controller for all in/out connections. This is a 
lot of fun, but also very unpredictable and therefore sometimes a 
bit frustrating.
Now I build a setup with mostly AS modules and it's very 
promessing.....
have a look at a site I made:

my question:
has anybody of you had any experience with soldering these 
connections? -- or with using changing connections as a way of 
performing? or any other tips?
best
Cor
