These modules can be controlled in 8 different modes of wich 5 exclusive:
1. Standalone by buttons.
2. Slave of the MATRIX II module linked to its preset and bank management.
3. CV Input with its bipolar offset setting.
4. MIDI NOTE or MIDI CC input.
5. Sequential switcher with a MIDI CLK input.
6. Sequential Switcher with a CLK/Trigger input.
7. Sequential Switcher with a CLK/Trigger + RST inputs.
8. CV & CLK/Trigger Inputs, like S&H
Two unique features increase the power of the different modes and their usabilities:
An "Arpeggiator-like" function is available for the Modes 5, 6 and 7 and including 4 patterns.
A "Steps Window" function is available for the Modes 3 until 8 and allows you to freely choose a range of steps in
number and location on the fly.

ALYSEUM
The SELECTOR module is a highly versatile module in terms of
connectivity, control, extension and use.
Its front panel, combined with a multitude of control signals,
sets it apart from other sequencer switchers.
The heart of the module is a high Voltage and high quality
bi-directional addressed Selector 8↔1, also called Sequencial
switcher 8 ↔ 1 or Mul6plexer 8 → 1 or Demul6plexer 1 → 8.
Up to 8 SELECTOR modules can be chained to create a bigger
Selector up to 64 ↔ 1.
In every cases, only one Switcher is active at a time!
The HOLD module is an optional SELECTOR module's
companion which adds the features to it:
8 digital addressed outputs, selectable between Trigger
or Gate.
1 CV input to 8 analog addressed outputs, selectable
between S&H or T&H.
The 8 digital and 8 analogue outputs are synchronized with the
SELECTOR I/O.
Modes, features and chaining of the SELECTOR module are fully
preserved when the HOLD module is added!

    For order to use the chaining feature, install the module #1 on the left first and then the module #2 on the right and so on. Thus you visually respected the LED chaining! When install both SELECTOR & HOLD in chain, place always per pairs HOLD-SELECTOR + HOLD-SELECTOR + ..Procedure: Only connect the module to a Eurorack bus board powered by a specified A-100 power supply.
  • Page 3 SELECTOR modules must be powered by the same power supply, or generally powered ON/OFF simultaneously with the MATRIX II. ● The MIDI Out of the MATRIX II module must be connected to the MIDI Input of the SELECTOR module. ● Please refer to the user manual of the MATRIX II for more informations.
