Q963 Trigger Bus

Q963 Trigger Bus

The Q963 Trigger Bus is an aid module for the Q960 Sequential Controller. The user can manually route each trigger output from the Q960 to one of 2 bus outputs - A or B. A center position is provided to prevent the trigger from going to either output, resulting in a rest for that stage.

Connection to the Q960 is done with a 24" cable behind the panel, so the Q963 must sit near the Q960. Up to 5 Q963 modules can be daisy-chained to one Q960 Sequencer providing a total of 10 trigger buses.

Installation is performed by simply plugging in the cable from the Q963 to the Q960's PCB. See this picture for details.

Width Feature Cable

Create distinct triggers for adjacent stages with the Q963WF Cable.
See the Q963WF cable page for details.

The Q963 provides real-time control of trigger outputs from the sequencer resulting in interesting patterns and control of rests (trigger off).

Multiple buses provide a way to route selected sequencer stages to different envelope generators and patch paths.

Combining Triggers
It's important to realize that each trigger output of a Q960 sequencer is On for the entire time that the stage is On. This means that when adjacent triggers are combined using a Q961 Interface or Q963 Trigger Bus it results in one long trigger instead of distinct triggers.

You can create distinct triggers at the Q963 output using the special Q963WF cable which connects the Q960 to the Q963 behind the panel. This results in independent triggers for adjacent outputs but has the side-effect clamping the Q963's output OFF if the Q960's internal oscillator is off. This can occur when using an external oscillator to shift the Q960.

Another way to create distinct triggers at the output of the Q961 Interface or Q963 Trigger Bus is to use a Q128 Switch to perform a logical AND on the output of the Q963. The patch is simple:

Q963 output --> Q128 A input
Q960 Oscillator out --> Q128 control input
Q128 common jack --> The new gate

When using an external oscillator to shift the Q960, simply patch it to the Q128 control input - instead of the Q960's oscillator output. When using the Q960's internal oscillator, the resulting triggers will have a 90% On-time.
