I have some quick questions. :P First is I read the wiki but I still don’t understand AOUT DOUT AIN DIN what is there function?
Also what would I need for a complete control surface with only one sid. From what I know its a core module, a sid module, and then what? Basically I want a full fledged Midibox Sid with only one sid. Thanks for the help, You guys are the best!
Complete Control Surface (Step C)
Description
Additional parts and modules:
n x core modules
m x SID modules
the minimal control unit (see above)
an improved PSU (ca. 1A) - the C64 PSU should be prefered due to the seperate +5V output for the core module(s)
3 DINX4 modules
2 DOUTX4 modules
14 additional rotary encoders (in difference to the datawheel, non-detented encoders are recommented here, but detented will also work fine, for example M-SW-ROT from Voti or the Bourns encoders from SmashTV’s Shop)
32 additional buttons
99 LEDs
ca. 2-3 veroboards for mounting the buttons/encoders/LEDs
a nice frontpanel
Costs: most expensive parts are the rotary encoders (ca. 15 EUR) and especially the frontpanel (selfmade ca. 25 EUR + a lot of time, premade ca. 100..150 EUR!)
Thanks, is that the one TK uses?
TK uses the CS-Step C
In the Manual you can see the OLD Version of CS-Step 3. The LED-Matrix have now a 8. Line his calles Volume. You can select the SID Module per core (Left and Right).
Here a List what the Modules are do:
AIN: Analog Input
Thats for Controle Voltage apps
AOUT: Analog Output
Controle Voltage Outputs to controle Filters or Synths
DIN: Digital Inputs
For Rotare Encoders or Switches also . . .
DOUT: Digital Output
For LED´s or 7-Segemnts LED-Displays
For CS Step3 you need 3 4xDIN Modules and 2 4xDOUT Modules (look at the standart DINPUT and DOUTPUT Shematic at the SID_Manual).
and then the Encoders, Switches an LED´s.
By 3x4 din do you mean 12 modules? sorry :'( i dumb
ooh, ooh, thats a question I think I can answer! on uCapps there are different versions of the DIN module listed. he means 3 DIN modules which have the 4 “74HC165” ICs.
here is a schematic off uCapps:
and here is an example of a 3DIN module:
anyone feel free to correct me if im wrong, and bludgeon me over the head with a hammer 
Just a sidenote, it may pay to be precise with the terminology to avoid confusion. a DIN is one single pin, which you would connect to a switch. A DINx4 is a module with 4 Shift registers on it, each one having 8 DIN’s.
So, those pictures are a DINx4 and DINx3 module.
Okay sorry for bump but get me right, (I know will be using 2 SIDS) I need 46 buttons, 99 LEDS, 15 rotary encoders (I thought I needed pots?), 3 DINX4, 2 DOUTX4, 4X20 LCD (I like that one best), and the veroboards. Thanks I’m sorry for my nuisances! :-X
with things like buttons, LED’s and Encoders, etc.. i would order WAY more than you think you need because you are most likely going to use them on other projects… especially seeing as you’ve posted your build list a few times in other threads. 
Haha thats right, I’m doing my initial megaparts order soon for lots of future projects because I’m finally getting a decent work area set up!
