S-161 16/32-step trig sequencer (4HP)

S-161 Trig sequencer module for Eurorack / Doepfer A100 system.

Quite self-explanatory trigger sequencer, some hints about concept:
– top button above display – short push switches between pattern (P) and chain (CH) display, long press goes to setting menu
– pattern can be 2-16 step long in 16-step mode or 2-32 step long in 32-step mode (last parameter in menu – mode 16/32)
– patterns can be chained (by their numbers) on the chain display, 16 memories for chains
– in pattern – turn knob while pressed to draw or delete more steps in a row

– chain is always played forward and can be repeated or stopped (one-shot play, then needs the reset to play again), “dot” is empty pattern
– “clk display” and “cursor display” parameters in menu are times is seconds, clock/cursor mark dissapears after this time to display clear pattern if there is no movement
– preloaded patterns are organized like “BD, SD, HH, perc” so patterns 1 and 5 are basic 8-beat BD, 9 and 13 16-beat BD
– there are 16 patterns (16 memories for your patterns) and up to patterns can be chained,  so max. sequence length in chain before repeat is 512 steps (32step in pattern * 16patterns in one chain)

Width: 4TE/ 4HP/ 20mm
Depth: 45mm /1,8″ max.

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.
