Test Mode

A Test Mode has been implemented since firmware 1.04 in order to test the unit while building it.

Pressing F1 and F2 and Power On unit load to Test Mode.

This allows you to test the switchs and LEDs and potentiometers of the interface.

Pressing a switch highlights the LED next to it. Moving a potentiometer shows its position between 0 and 127. The display is used to show you the action. It does output similar messages through Serial USB too (115 KBauds). This allows you to see which switch/LED is defective or which potentiometer has jitter (99% it is an unsoldered potentiometer).

 

Pressing KEY2 and KEY3 and KEY4 reboots the System (and leave Test Mode).

 

Moreover a permanent test has been implemented to test the Midi connection by SysEx messages. The following messages need to be sent to the Matrix Ctrlr Midi Core input :

The Ctrlr answers on its display to those two messages ????

Matrix Ctrlr 1.38 update

There is a long time we have published some news !

We (or should say “I” as alpesmachines is a single guy project) have been focused on daily life things and a regular job but some prototyping projects should be exposed in the next weeks …

We have also invest some time to enhance the Matrix Ctrlr and you can find the latest revisions 1.38 on Github here :

  • One major improvement is a faster display librarian : all the micro delays induced by printing on the display have disappeared. You can trigger very short notes and move all the parameters together now : beware to the musical results !
  • ARP Menu : now you can set the split point in between the arpegiated section and the sequenced one with a midi learn : simply press KEY2 under SPLT and send a midi note to define the split point. A customer request !
  • We have also improved the ADC stability by using a moving average method to filter power supply noise and thus having a more stable reading of the potentiometers. It can be access under the CFG/MISC/JTR parameter. A lower value uses lots of filtering (drawback the calculus is longer so the printed value is a little delayed) while a higher value is more responsive and sensitive to noise. The value can be set by pressing KEY4 and saved with PAGE. Now you can use a very bad quality power supply if you like.

We still have a few kits in stock and you need to order a Matrix Ctrlr ECO kit + assembly service to have a ready to use unit.

We recommend to have firmware 1.20 or 2.15 inside your Matrix 1000 or Matrix 6 : we provide Oberheim EPROM if necessary.

 

 

There are also Stereo One-O-Six Chorus kits in stock, a nice companion to add wide stereo effect to a mono synthesizer !

We wish you all the best and enjoy the unlockdown freedom !
