Manual control of internal clock frequency.

CV attenuverter for internal clock frequency.

Clock mode: Red = low, Orange = normal, Green = double. Double

mode reacts to BOTH rising and falling edges when used with external

clock.

CV input for internal clock frequency.

Mix output.

Attenuverting mixer. Center position mutes channel at mix output. Turning clockwise adds the

corresponding channel to the mix. Turning counterclockwise subtracts it. On the A mixer, the mixer

adds to only one "side" of the mix waveform. On the B mixer, it adds to both.

Individual output for channel. The A outputs are optimized for gate generation, while the B outputs

are designed for audio signals.

External clock input. Disables internal clock controls when used.

SHIFT REGISTER TIPS:

If a tap configuration is "maximal", then it is the longest possible sequence for that number of bits. For example, an 8-bit maximal LFSR has 255 states, a 7-bit has 127state, a 6-bit has

63 states, and so on.

Shorter maximal shift register lengths have a higher "pitch", as they divide the input clock by a smaller number.

All configurations with an odd number of taps are non-maximal.

Non-maximal sequences are divided into a number of different sequence lengths, selectable at random by pulsing the "SEED" input. The seed input will update all eight outputs Try

creating rhythmic shifts of timbre or sequence by creating a mix of several non-maximal registers, and then sending gates to the Seed input.

A table of maximal shift register configurations is given below. All of these are available onboard the Zorlon Cannon.

The eight outputs can each have a different configuration. To edit, hold down the "output select" button and turn the rotary

encoder until the desired output is illuminated with a GREEN LED. Now, release the output select button.

Each jack represents the output of a shift register. Turn the encoder to define the length of the register which is visually

represented on the display. Then, you can press the "tap/length" button and continue turning the encoder to select the

feedback tap configuration. These parameters determine the "period" of the pseudorandom sequences.

When you have edited the outputs to your satisfaction, you may store them to memory by pressing down on the rotary

encoder knob for 2 seconds. The "range" buttons will blink once to confirm this storage. To reload the stored preset, double-

tap the encoder knob quickly without holding it down.
