S-142 4-step sequencer for Eurorack / Doepfer A100 system.
It can work in 4 modes (selectable by internal jumper), just one jumper header must be set (on one of top four “mode” jumpers).
Fifth jumper (most bottom just under mode selection jumpers) sets reset behavior in “clock+reset mode” – incomming reset moves sequence instantly to first step (fifth jumper header set) or to last step (jumper header removed).
Top input and bottom input according to selected mode then works as:
– clock (top input) + reset (bottom input) – leading edge of reset signal moves seq instantly to step 1 or to step 4, see fifth jumper setting above
– clock + direction – active gate in bottom “direction” input reverts sequence direction to 4-3-2-1-4-…, non-active moves sequence in normay way 1-2-3-4-1-…
– CV + confirm – leading edge of confirmation gate (bottom input) moves sequence instantly to step according to CV “address” (top input)
– CV + disable – active gate “disable” freezes sequence at current step
Top input jack receives trig/gate/clock/CV signal (depends on selected mode of operation), bottom input jack is for trig/gate.
Thresholds (in CV address modes): negative to +1,2V = step1, +1,2 to +2,5V = step2, +2,5V to +3,8V = step3, above +3,8V = step4
Output range 0-5V or 0-10V (selectable by internal jumper, jumper header set = 10V output range, removed = 5V output range)
Width: 4TE/ 4HP/ 20mm
Depth: 40mm /1,6″ max.
Current: 20mA (no need for +5V supply)
Power cable included (red strip down) 🙂
Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
