Well well, here i am with a question that probably been asked several times before.
Its damn hard to find this info among all the other discussions in this forum
Im goin to connect the polivoksfilter to a shruthi with a smr-4 and a programmer.
Witch connections do i have to make?
Do i have to solder a wire from all the pads on J4 and J6?
Wire the SMR-4 to +5V GNS OSC VCA on the Digital Boards stacking connector
Wire the SMR-4 F to the Digital Boards CV1out
Wire the SMR-4 Q to the Digital Board CV2out
Set Filter to Polivoks and CV to Programmer in the System Pages (and save these!)
Now the Programmer is Operated by the Output Expansion Port, The Polivoks Filter Modes are switched manually and the SMR-4 CVs are Fed by the 2 additional (most likely unused) CVs from the Digital Board.
Next time well try to make the Shruthi brew Espresso.
The 595?
Pichenettes was writing about the switches and removing the CD4053?
"If you want to use this filter board with manual control of the filter modes (for example from a Sidekick, or from a Shruthi=1 hooked to a programmer), just remove the CD4053, and look at the spot on the PCB with 3 pins marked âLP BPâ. Connect a SPDT switch there, with the center pin connected to the first pad, and the 2 other pins connected to the pads marked BP / LP. You now have a manual BP / LP selector.
To activate the FM feedback, connect the two pads marked FM (a switch can be used to make this connection switchable)."
So if i understand this correctly:
I use the polivoks as the standard filter with the digital board,
(if i do not want the switches i just leave the filter as is?)
and after this i connects 6 wires to the smr4?
YOu can as well replace the 4053, i found recreating the Digital Signals that drive the 595 a bit more elegant as it doesnât touch the original Audio Path and neither runs your precious Audible Signals thru Meters of additional Wire picking up noises et al nor adding nasty switching Transients from the ToggelSwitches⌠(as if this would matter once cranking up the Overdrive )
Its up to your taste, recreate the Signals that switch the 4053 (remove the 595) or Switch it all by yourself replacing the 4053 (and probably removing the then useless 595)
fcd72âs wiring scheme is smart, please follow it!
Also, running audio signals through 4051 or 4053 definitely has an impact on sound. Iâm going to sell a magic FX box in which the signal goes through a chain of 4051s for nailing that sound (with true-bypass relays of course).
This looks doable
I will go for the removal of the 595.

Could you explain this to me (like you talk to an idiot monkey)?
My Grandma tortured me with Sanostol and Rotbäckchen but i guess its a bit to late for both of you.
Honestly, i got most of my Knowledge about digital (hence i manipulated the 595) chips from a small TTL Logic Kit with a single 7400 in it my father gave to me when i was 8 or 9âŚ
