Håkan Müller, creator of the Hamu devices passed away in May 2018. He suffered from ALS for 3 years and finally decided to leave. To honor Håkan, you can use his Rack Extensions for free from now on. Please remember Håkan when you are inking your rack purple.

The ModSelsor enables you to select and sense CV signals in a variety of ways.

A CV level on the single Select input will activate one of the up to 24 outputs, to a level set by a modulation input.

Release 1.2.1 includes three new functions:

  • A new Hold option will retain the level on each selctor output after it has ceased to be selected.

  • A new Selected Sense output will output the sense input of the currently selected position.

  • A new Sense to Select option will use each sense input level - if attached - as select output level when selected.

The index and level outs of the Sensor are of course still available.

Product details

With the 1.2.1 update of the ModSelsor, the Selector and Sensor parts are more growing together, and will interact a bit depending on how you setup the switches and connections. Well, to be perfectly honest it's primarily the Selector functionality which is expanding in different ways... ;)

Please excuse us for not updating to release 1.2.1. New videos may be be added in a while, but the availablity of this release is more urgent.

THE SELECTOR

The CV level on the single input socket will select one or none of the up to 24 outputs. Only the range 0.0V to 1.0V on the input is significant, where 0.0V in will always activate output number 1, while 1.0V (or higher) on the input will activate the last connected output. A negative input level will activate none of the outputs. The cable connections define how the input level is mapped to the outputs, so that the last used output always maps to 1.0V in and the range of a step below.

Selector example 1: Understanding select in levels.

  • You put cables only in selector output sockets 1&2
  • ...input level range 0.0V-0.5V activates socket 1,
  • ...range 0.5V-1.0V will activate output socket 2.

Select modulation

New to release 1.1.0 is that the level of any active output can be set by a modulation input. When no mod cable is connected, the active output will default to +1.0V as with earlier versions.

Sense to Select switch

Since release 1.2.1, there is 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 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 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 follow it's sense input or select mod input, if these are attached.

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 is the level controller.
  • Connect a CV signal to the Select input, e.g. from a ModPanel knob. This is the target controller.
  • Switch on the Hold option.

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

THE SENSOR

The index output level indicates which input socket has the highest level at the moment. This is the opposite from the Selector, and the level mapping is similarly defined by the last used sense input socket.

An additional output is provided, always set to the current highest sense input level, i.e. the momentary maximum input level.

Sensor example: Understanding Sensor levels

You put cables only in sensor input sockets 1 & 2 => When input 1 is the higher, the output sense index level will be 0.5V (high end of range 0.0V-0.5V). When input 2 is the higher, the out index level will be 1.0V.
