There are 3 modules I use regularly on the Input side of my PSIM:
Blacet VC LFO - running at high speed, the 0~10v waves are great as a random voltage source.
Wiard Joystick - for easy 0~10v or a gate, nothing is easier; nice visual feedback too.
Blacet Mixer/Processor - perfect for mixing & shifting voltages; being able to easily invert and adjust bias comes in very handy.

I built this type of input structure for my PSIM and found it to be
REALLY useful so i endorse this feature strongly.
The added cost and footprint of the input summing amps (and the extra
knoibs & pots) can be easily bypassed if the user/kit builder does not
require them.
While i'm on the subject...
('oh boy' the list groans , 'we KNEW he couldn't stick to just ONE
topic in a message!')
let me describe a 'feature' that i added to my PSIM that i'm NOT
endorsing for the theoretical CVS gadget.
(but that might tickle the fancy of other bomb-throwing musical
bolsheviks out there)
i normalled a transistor-type analog noise (scaled 0-10V) to input
one. The inernal random function was 'repeating' a little too much for
my persnickety tastes in randomness. when i need a little
unpredictability left over from the big bang i just sample input one,
(assuming that nothing external is plugged into it) and voila! All i
have to do is scale the result, using simple division, to whatever
range is required by the software.
Rest assured the software i release does not exploit this
idiosyncratic mod.
to infinity! and beyond!
