6.19 Control Voltage Sequencer
The Control Voltage Sequencer module enables you to record sequences of voltage. This
module in itself does not produce sound but is used, usually instead of a Keyboard module, to
control other modules such as VCO, VCA or filters. 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 four 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 output is the control voltage signal.
This sequencer has 16 vertical bar sliders each controlling the output signal corresponding to
a given step. The output value ranging between -1 and 1 Volt can be adjusted by click-holing and
dragging or using the keyboard arrows once a bar is selected.
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.
