HAMU - Rack Extensions

ModSelsor is mainly a unipolar CV device.

Inputs will however accept any levels, but make sure to understand how negative values are handled before you rely on a particular behaviour.

Basic function of the Selector:

• The level on the Select input will select one of the active outputs.
• The input range between 0.0V and 1.0V is evenly split between the active outs.
• The last (highest) used (connected) socket and all positions below are active.
• A negative Select in level will de-select all outputs, i.e. all will be 0.0V and the select input LED will show a very dark orange glow (-0.1V).
• Positive values above 1.0V will be clamped to, and count as, 1.0V.
• The red output indicator LED of the selected output will be lit.

Selector example 1:

Understanding select in autoadjusting levels.

• When you put cables only in selector output sockets 1 & 2 this means
• ...the input level range 0.0V-0.5V will activate socket 1, while
• ...the input level range 0.5V-1.0V will activate output 2.

   

  Select modulation input

  Since release 1.1.0 the level of any selected output can be set by a global modulation input. When no mod cable is connected, the output level will default to +1.0V.

   

  Sense to Select switch

  Release 1.2.1 introduced a Sense → Select option, activated by a switch button. This will use the Sensor input of a position, if attached, as level source for the select output of that same position.

   

  Selector example 2:

  Selecting level from one of several sources to a common target.

• Connect 8 different CV signals to the Sense inputs.
• Connect the sense Selected Out to some instrument modulation input.
• Connect a CV input to the Select input, e.g. from a ModPanel fader.

Now you're able to assign any of those 8 different CV signals to your modulation target, by pushing the fader up and down.

Hold switch

Also since release 1.2.1 you have a switch button for the Hold option. This will leave any select output level where it is, when the position is de-selected. When selected next time, it will again get continuously updated to it's sense input, select mod input or 1.0V.

Selector example 3:

Controlling several targets from the same CV source.

• Connect 8 different targets, e.g. instrument modulation inputs, to the Selector outputs.
• Connect a CV signal to the Selected Mod input, e.g. a ModPanel fader. This will be your level controller.
• Connect a CV signal to the Select input, e.g. from a ModPanel knob. This is now the target controller.
• Switch on the Hold option.

  You're now able to handle any of those 8 different CV target levels from the same fader, after selecting target with the knob.

   

Basic function of the Sensor:

• The Sense index output will indicate which of the active sense inputs is highest.
• The index range is 0.0V to 1.0V and is split evenly between active sense inputs.
• The last (highest) used (connected) socket and all positions below are active.
• Any input level is accepted, so negative levels are lower than open sockets (0.0V).
• If more than one socket have the same level, the first (lowest number) is considered the highest. Also applicable to open sockets!
• When no input cable is connected, the output index level will be negative (-0.1V). The LED will have a very dark purple glow.
• Should all active inputs be negative, the sense level output will also be negative, and the level LED will reflect this.
• There's no clamping of input or output levels, so the sense level output will be exactly the same as on the corresponding input.
• The red input indicator LED of the currently highest input will be lit.

Sensor example:

Understanding the sense index output autoadjusting levels.

• You put cables only in sensor input sockets 1 & 2 , and get the following outputs
• When input 1 is the higher, the output sense index level will be 0.5V.
• When input 2 is the higher, the out index level will be 1.0V.
