bEuclidean Rhythm Generator
Switch to this mode by holding down the t shift button
while pressing the b euclidean rhythm generator button.
The Euclidean rhythm generator generates patterns on principle, which
Euclid described for the rst time around 300 B.C.
The generator overwrites the current track with the generated pattern - this
means that you can then adapt the pattern to your own needs.
The algorithm uses the parameters steps, oset and length to arrange the
steps. In the illustration above you can see how these parameters change
the patterns. The settings can be selected via the white buttons 1-3.
Steps
Press the rst white button and set the number of steps from 1-16 with the
orange buttons.

About
The SWT16+ is a 16-track Eurorack step sequencer with up to 64 steps
per track. The module makes it possible to create up to 8 dierent patterns
which can stored in a total of 16 presets. Programmable like a classic TR
machine, the SWT16 can be used not only for triggering drum sounds but
also envelopes or other modulation sources. This manual gives an over-
view of the many ways in which the sequencer can create and inuence
rhythms.
Installation
The SWT16 requires a ±12V power supply (2x5-pin connector). The red
strip of the ribbon cable (-12V side) must be oriented on the same side as
the «Red Stripe» mark on the board. The module draws about 70mA from
the +12V rail.
