Admiral - Modules for VCV Rack

This is a work in progress collection for Rack version 1.

Divisions - Clock Divider and Polyrhythm Generator

divisions screenshot

Divisions is four clock dividers and two auxiliary inputs that act as trigger sources. Each trigger can be routed to one or both of the available buses, and the slider controls the gate length.

The module has three outputs towards the bottom that will be high when their selected buses are high.

The four clock dividers can be controlled by CV (0 - 10V) and if a jack is connected the knobs will act as attenuators to limit the range of the clock division.

Shifts - Hybrid Bernoulli Mixer

Shifts is a hybrid mixer and Bernoulli gate. Each knob mixes linearly between two things as long as the knob is in the top part. When going beyond the gray markers and pointing the knob down it starts acting as a Bernoulli gate letting the other side take over more and more.

When a knob is in the Bernoulli zone it will always fully choose one of its two channels: deciding which one by flipping a coin at each trigger from trig if connected or from ab if not. The probability of the coin toss is skewed according to the position of the knob. This is how all three knobs of the module work.

The top section distributes ab or pans it between A and B according to the top knob and can be modulated with +/-5V CV through aΦb. This can act like a panner or a standard Bernoulli gate.

The middle section controls the input of the bottom section. The two options are x for using the external a and b inputs or X for using the outputs from the top section A and B. The knob acts the same way as the other knobs so it is possible to mix between the top section X and the external input x either linearly or randomly shifting from one to the other using Bernoulli gates. Both the A/a and B/b mix will be affected the same and can be modulated with +/-5V CV through XΦx. This can act like a send-return to two different effects or a simple mixer.

The bottom section: AB is mixed from a and b according to the top knob and can be modulated with +/-5V CV through AΦB. AB is a linear mix of a and b or shifts from one to the other if the knob is in the Bernoulli zone. This can act like a mixer or a reversed Bernoulli gate.

Tables - Quad Sequencer

Tables is four sequencers in one module. Inspired by the Metropolis and the Ryk M-185, Tables focus is more on the rhythm and randomness control than on the melody.

Tables has two rows of outputs, the top one are the main gates for the four sequencers and the bottom one emits a trigger for each sequencer when it goes from one stage to the next.

Each of Tables' four sequencer has eight stages than can be programmed using the buttons in the mod and sel columns. The bottom sel switches between sequencers: the green light indicates which one is currently being programmed.

Selection

The top eight sel buttons select which and how many steps the corresponding stage will use. This is indicated by how many lights become dimly lit in the stage.

Each stage will take as long as there are active steps in it. The maximum number of steps is four. When steps have empty lights in front of them in the pattern the number of empty slots indicates the probability of that step being muted. The total time a stage takes doesn't change with this randomness, only the gates being outputted during the stage do.

In general the probability a step will play is 1 / (1 + number of empty spaces). How this interacts with Stage Modes is explained in the Stage Modes section below.

Modes

The mod column of buttons are used to switch between four modes for each stage and between four modes for the sequencer itself. Which mode is currently being used is represented in binary by lighting the mod and neighboring col buttons.

Let's list all the possible modes:

Stage Modes

These modes are chosen with the mod buttons in front of the eight stages.

  • . .: wait mode will simply wait during the given amount of steps. Randomness in stage selection has no effect in this mode.

  • @ .: first mode will only output a gate for the first step in a group of adjacent steps. This allows for a short pulse with the number of steps after it being the amount of time we wait before the next stage. Randomness requires gaps in the pattern and will cause this mode to output multiple gates in a single stage.

  • . @: all mode will output a gate for each step in the stage. Randomness has the effect of muting the gate directly after the gap.

  • @ @: join mode will output a gate as long as a group of adjacent active steps. Randomness has the effect of muting each group of steps according to the probability indicated by the size of the gap in front of it.

Channel Modes

This mode is global for each of the four sequencer and is chosen using the bottom mod button.

  • . .: forward simply iterates over all stages in order top to bottom and then cycles starting from the top again.

  • @ .: random picks a random next stage each time one is finished, it is possible it picks the same one again.

  • . @: brownian has a 50% chance of picking the next stage, 25% chance of repeating the same stage, and 25% chance of picking the stage above the current one.

  • @ @: reverse iterates over all stages from the bottom to the top then cycles starting from the bottom again.

Watches - Switched Multiples

watches screenshot

Watches is a passive multi-connector similar to a classic multiple. What's different is that each socket has a 3-position switch to connect the jack to one of three internal buses.

All inputs on a bus are added together and sent to the output jacks connected to that bus.

The top section has three inputs and two outputs, the bottom section is the opposite and has two inputs and three outputs.

Normally Watches is separated in a top and bottom section that act independently. When the + button is red the top three buses are connected to their bottom counterparts and the module act as one.

The neutral switch position connect jacks to the middle bus. The middle bus is special and acts differently according to the 2:3 switch:

  • On 2 only two buses are active, the middle bus mutes.
  • On 3 the middle bus is independent in each section.
  • In between the middle bus is shared between the two sections even when + is not active and they otherwise act independently.
