Overview

This module has four MIDI inputs and one MIDI output. Internally it implements a switch, such that messages 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. You can use this module for the same purpose in Numerology: Create 4 sequences with any 4 Note Sequencer modules, connect them to a MIDI Switch, then have a clock change the switch as each sequence finishes. Since Numerology's Note Sequencers can be up to 128 steps long, this 4-input switch allows you to build sequences of up to 512 steps.

There are also several other techniques that this module can be used for, if you treat it as a 'live arrangement' tool. For instance, you can use it to randomly switch between patterns, or to introduce a new part that only appears every few bars (drum fills, for instance). Or you can construct a 'mashup' pattern by quickly switching between existing patterns.

There is a module equivalent to this one that works on CV signals, the CV Switch.

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.
  
  
• 0.0 to 1.0 : 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 for details.

The First MIDI Input for the switch.

The Second MIDI Input for the switch.

The Third MIDI Input for the switch.

The Fourth MIDI Input for the switch.
