6.23 Dual Gate Sequencer 89
6.23 Dual Gate Sequencer
The Dual Gate Sequencer module enables you to record two sequences of gates at the same
time. This module in itself does not produce sound but is used, usually instead of a Keyboard
module, to trig other modules such as Player or drum sounds. This module is a very complete
16-step sequencer, which means that it plays sequences or patterns of 16 notes in loop. Sequences
can be set to have 1 to 16 steps. Because each sequence represents a bar containing four quarter
notes, each step of the sequencer itself represents a sixteenth note. The module can memorize 32
different sequences between which you can switch while playing.
This module has three inputs and five outputs. the first input is a sync signal which controls
the tempo from an external source, the second is a start/stop input which will start the sequencer
when it goes form 0 to 1 volt and stop it when it goes from 1 to 0 volt. The signal can come from
another sequencer or a Keyboard. The third one is a reset input which will restart the sequence
from beginning when it goes from 0 to 1 volt. The first three outputs are the same as the inputs
(sync, start/stop, reset) and are used to control other sequencers. The fourth and fifth outputs are
gate signals which can be used as control sources to trigger other modules.
This sequencer has 2 sets of 16 gate buttons. Each has its own gate output that will generate
a square pulse of 1/8 of a quarter note for each active gate buttons. The two sets of 16 shift knobs
delay the output of their respective gate. The loop buttons are used to set the length of the pattern
from 1 to 16 steps.
Creating Patterns
To create a pattern, you must first select its location. You can select it with a combination of letters
(A, B, C, D) and numbers (1 to 8), on the front panel, giving you a total of 32 patterns. The
sequencer will loop each time a pattern ends. To make the sequencer stop at the end of a pattern,
the once button must be clicked.
The patterns can be played following 5 play modes using the mode control. Forward (FWD)
plays the pattern incrementally. Backward (BWD) plays the pattern decrementally. Pendulum
(PEND) plays the pattern forward then backward. Random 1 (RDN1) plays the pattern randomly,
the same random sequence is repeated when looping. The reset button is used to generate a new
random sequence. Random 2 (RDN2) plays the pattern randomly changing the random pattern
when looping.
