Matrix Ctrlr Livepanel

The live panel consists in the Knobs and selection switches.

When you turn a knob, the parameter description is written on screen with its original value in the patch in the top left corner. The bottom left corner indicates the current value encoded by the potentiometer. A gauge gives an estimate of your potentiometer position : you hear it, you feel it with your fingers, you read it and you visualize it, Human User Interface at its maximum !

It is a real time feature, whatever menu you are in. The Matrix Ctrlr has 32 knobs organized in 2 layers, which give you a direct access to 64 controls (like a digital mixer). To access the second layer you need to activate ALT.

Only relevant controls have been retained and printed on the overlay, but you can edit pots.ino in the code and add more parameters ! You can also edit the delay you return to menu after potentiometer’s inactivity in the code (default : 2000 millisec).

Notice :

G.Detune stands for Unison Detune introduced in Matrix 1000 GliGli firmware. It sends a control change midi message #94, from 0 to 63 (127 is definitely too much) affecting both DCO1 & DCO2. Matrix 6/6R doesn’t responds to this. That gives a very varnished vintage touch to any patch as if the oscillators were detuned by the years, very 70s. This feature has been kept in firmware 1.20 by Tauntek.

Detune stands for Detune of DCO2 (standard feature).

PWM/LFO2 means Pulse Width Modulation by (/) LFO2. The slash / can be understood as “modulated by”.

Matrix 6/6R 2.14 firmware : set up 04 SYSEX EN +2 in MASTER to enable the correct range of responses to SysEx messages. Detune doesn’t accept negative values (corrected in 2.15).

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 !
