S-386 Probability sequencer (4HP)

S-386 Probability sequencer module for eurorack / Doepfer A100 system.

From the top down:
Clock input jack + LED
Reset inpout jack + LED
Display + encoder
Ch.1 output + LED
Ch.2 output + LED

This is a two-track 16-step trigger/gate sequencer. Steps are generated according to its probabilities. 61 common memories (0-60) shared between patterns (more likely “probability maps”), step probabilities are displayed as bars (height = probability) or as numbers 0-14 (0=never, 14= always) or in hybid view (bars and numbers, dot = never, numbers = probabilities, full bar = always). It can be used as ordinary regular 2-track trig/gate sequencer if 0 and 14 probabilities are used only (but some probability avoids common “machine” repetition by changing pattern occasionaly on selected beats).

Menu setting (enter and exit menu by holding encoder):
Pattern length: 1-16 step
Trig length : 1-10ms or =IN (the same as input length, it can pass gates)
Reset behavior : stay = first step is made with first clock after reset, first=reset itself makes first step, last=reset itself makes last step
Symbol: bars, numbers or bars + numbers
Exclusive/priority: off = both tracks can generate output, 1 = exclusivity and priority of 1st track, 2 = exclusivity and priority of 2nd track
Rollover: none, values, cursor, all (reaching max. value and turning to the right holds max. value or jumps to min. value)
Dissapear: clock, cursor, both none (after some time clock and/or cursor dissapears from display to make display clearer)


Width: 4TE/ 4HP/ 20mm
Depth: 46mm /1,8″ max.
Current: 25mA
Power cable included

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.
