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 !
