Overview

This module has four CV inputs (labeled A, B, C & D) and one CV output. Internally it implements a switch, such that signals from only one input are passed to the output at any given time. The Switch parameter always displays which input is connected to the output. There are three different ways the switch value can be changed, based on the Mode parameter:

• If the mode is "Clocked", then the switch moves to the next input every X beats as determined by the value of the Clocked Beat Length parameter.
  
  
• If the mode is "Sequenced", then the switch position is determined by the value of the "CV Prog In" CV input. The Input Range parameter, visible when this mode is selected, determines how the CV input value is used to determine the switch position.
  
  
• If the mode is "Manual", then the switch only changes when you choose a new value for the Switch parameter directly, or when a CV trigger is detected on the Trig In input port.

Regardless of the mode, you can always manually adjust the switch, or use a CV trigger source (such as a Gate Sequencer) connected to the Trig In input.

The traditional use for a switch module, such as on a Moog Modular, is to allow you to build longer sequences from a set of shorter sequences, by having the switch move from one input to another in sequence. If you are using CV Sequencer modules in Numerology, you can use this module in very much the same way you would on an analog modular synthesizer: Create 4 sequences with any 4 Numerology CV or Gate Sequencer modules, connect them to a CV Switch, then have a clock change the switch as each sequence finishes. Since Numerology 2's sequencers can be up to 128 steps long, this 4-input switch allows you to build CV sequences of up to 512 steps.

If you are using Note Sequencers to generate your source patterns, and you want to combine them to make longer patterns, then you will probably want to use the MIDI Switch module instead of this one. It allows you to switch between streams of MIDI messages.

Parameters

Clocked Beat Length
This parameter is only visible when "Clocked" mode is set. This parameter determines the number of beats between switch changes. The switch will cycle from one value to another in sequence and then repeat: A, B, C, D, A, B, C, D and so on. The switch will reset when the master transport is reset.

Input Range
This parameter is only visible when "Sequenced" mode is set. It determines how values on the CV Prog In port are used to control the value of the switch. The value are as follows:

• -1.0 to 1.0 : input values are mapped from this range to the range 1.0 to 4.0, the values are then truncated (converted to integers), then used to select one of the four switch values.
  
  
• 0.0 to 1.0 : input values are mapped from this range to the range 1.0 to 4.0, the values are then truncated (converted to integers), then used to select one of the four switch values.
  
  
• 1.0 to 4.0 : input values are truncated, then used to select one of the four switch values: 1 -> A, 2 -> B, 3 -> C, 4 -> D.

Ports

When running in "Clocked" mode, the module must have a clock input set so it knows when to switch values. This port will be automatically connected to the clock bus for the current stack when it is added to the stack.

A Trigger input for the switch. Whenever a trigger is detected, the switch will move forward (A, then B, then C, etc).

When running in "Sequenced" mode, this input allows you to set the value of the switch based on any CV source with an appropriate range. There are three range values possible, see the Input Range parameter below for details.

The First CV Input for the switch.

The Second CV Input for the switch.

The Third CV Input for the switch.

The Fourth CV Input for the switch.

The CV Output for this module.
