Preparation

Preamble : prepare before acting

In order to assemble the kit you will need the following tools:electronic_tools1_description

  • soldering iron
  • solder wire
  • flat pliers
  • cutting pliers
  • a multimeter (voltmeter, ohm-meter, shorts)

 

 

Sort the componematrix_ctrlr_building_parts6nts on a tray, and compare them to the parts-list. Make sure you’ve got the right amount of parts!

 

It’s a good idea to work on a clean table. Placing components on a tray allows you to pause your work and come back to it later if necessary.

The kitchen is the perfect place to find containers for components.

You will solder components from the shortest to the tallest.

Notice that some components are polarized and need to be inserted in a certain way (respective of their positive and negative leads) while others are not and can be installed in either orientation. Non-polarized components like jacks or potentiometers need to be inserted correctly to work as expected by the firmware (follow the footprint).

unpolarized : resistors, small capacitors, trimmers, potentiometers, encoder, jacks, switches.

polarized : chemical capacitors, diodes, LEDs, ICs, DC barrel jack.

It’s now time to solder.

Matrix Ctrlr firmware v1.42

A new Matrix Ctrlr firmware is available on GitHub as a free update :

  • better workflow to save the patches (turning the encoder show temporarily the name and the position). Thanks to Thomas P. Heckmann for the help !
  • minor enhancements on boot to reach quickly Test Mode.
  • Chord Memory based on Roland alpha Juno feature

 

On page5 of ARP menu, 3 different chords (e.g : Major, minor and 7dim) can be memorised at the same time and you select the one you need  :

They are empty by default. To create a chord in cm1 slot, press KEY3 to select. Press KEY1 to record the chord. Play a chord on your keyboard (6 notes max), release. The chord is in memory cm1 (wiped on power off). You can immediately find back this chord by pressing C4 (midi note 60) on your keyboard and transpose it all along the other keys ; this is very inspired by alpha Juno.

 

 

Many people are asking for Matrix Ctrlr kits. We are working on it, but you may know that the prices of the components have been multiplied by 2 or 3 lately, especially semiconductors – and there is a chips shortage on top of that ! Taxes and freight are also higher, so we do our best to keep costs down (we have to be very creative). You may expect a little rise in our prices …
