OB-6 Operation Manual
Global Settings
1. Seq Jack: NOR, Tri, Gat, T-g (Normal, Trigger, Gate, T-G)—Selects
the mode for signals received on the rear-panel Sequencer jack.
• With normal selected, a footswitch will start sequencer playback.
• With trig selected, an audio signal connected to the sequencer jack will
step the sequencer when the sequencer’s
play button is on.
• With
gate selected, an audio signal connected to the sequencer
jack will trigger and gate the envelopes while you hold a note or
chord. Additionally, turning on the sequencer or arpeggiator will add
sequencer or arpeggiator playback—but controlled by the OB-6’s clock
bpm and value settings and not the audio trigger.
• With
t-g (trigger+gate) selected, an audio signal connected to the
sequencer jack will trigger and gate the envelopes while you hold a
note or chord. Additionally, pressing the sequencer’s play button will
also add synchronized sequencer playback.
For best results when triggering the sequencer with an audio signal, use a loud
signal with a sharp attack/decay and little or no sustain.
2. Pot Mode: Rel, Pas, Jup ( Relative, Passthru, Jump)—The rotary controls
on the front
panel are a mixture of “endless” rotary encoders and potenti-
ometers or “pots.” The pots are identiable by their lined knobs and the
fact that they have about 300° of travel. There are three pot modes to deter-
mine how the synth reacts when the programmable parameters are edited.
(Master volume is not programmable, so these modes don’t apply.)
In Relative mode, changes are relative to the stored setting. In Relative mode, the
full value range is not available until either the minimum or maximum value and
the respective lower or upper limit of the pot’s travel is reached.
For example,
the resonance parameter has an internal value range of 0 to 127. Let’s
say the physical position of the resonance pot is the equivalent to a
value of 100. If you switch to a program that has a stored Resonance
setting of 63 and turn the pot all the way up, it will only go to 90. To get
to the maximum value of 127, you rst have to turn down until the value is
at the other extreme and the pot is at the limit of its travel (in this case, 0
and fully counter-clockwise, respectively).
In Passthru mode, turning the pot has no effect until after the edited
value equals the preset value (that is, until the edited value “passes
through” the stored value).
