Interesting projects for music synthesizers and anything else electronic or embedded software related…….Plus music from supporters of this site.
For details of fabulous forthcoming projects, for example Roland JD800 keyboard flexible PCB, see the Developments page, a diary of engineering events as we progress them.
Installation of Vecoven Digital PWM Modification
Fred Vecoven has released a new version of the PWM modification for the SuperJX that is based on the JX8P PWM modification. It is obviously audibly identical to the Analogue variety but doesn’t require extensive wiring but de-soldering instead. As well as a neat fit, it reduces current consumption significantly meaning that the instrument runs much cooler. See the fitting guide inside the maintenance section.
Roland JX8P Replacement Display
To celebrate the 5th anniversary of SuperSynthProjects, we have launched!
A fabulous OLED display that replaces the old VFD in the Roland JX8P. When used with the Vecoven SuperJX Flash, it enhances the function with a intuitive 2 line display that helps guide you through the new features of the plug and play flash module.
The two line display set with Vecoven firmware so far implemented is shown below:
A detailed set of instructions are now available that also show the history of the project.
Check out the Development page for a history of the project. From an initial play around in August 2020, this beautiful enhancement helps extend and breathe new life into this fabulous instrument. Some further improvements have been made to the SuperJX OLED module on the back of the JX8P code base and all displays continue to be developed and improved with easily downloadable updates.
A quick run down of the display when used with a Vecoven flash module is shown in this video.

Recording the Dark Angel Symphony
NEW MKS70 OLED Module
A specially designed OLED display replacement for the MKS70. Using a low width 40×2 character module, it is a simple fit with prepared wiring that only requires the Display Board to be removed and drilled. A very neat and high precision installation is achieved by use of the original VFD fixing pins.
OLED improves on LCD by having high contrast ensuring a clean display and gives enhanced functionality that the Vecoven software exploits for the VFD update using just a 40 character by 2 line display. Like all other displays, works with original Roland software in single line mode. Availability is shown here.
Fabricio Cantoni has put in a huge number of hours and dedication to create this fabulous looking JX10 all in white. The attention to detail on the new silk screen is stunning. It is running Roland firmware, contains a replacement display whilst being controlled by the iPG800 iPad App.
Here are more pictures showing how perfect the detailing is in the artwork in this unique looking instrument.

80’s Magic With JX10
A song created by Thomas Östberg using the JX10 for all sounds with exception of the drums and a small number of effects. The link below takes you to the SuperSynthProjects google drive and plays in Chrome.
It is pure JX10 80’s magic. Somehow, Thomas has rolled so much of that era into the melodies and arrangement. After listening all the way through, one is left with a head full of classy riffs and different ideas, with the meticulous arrangement being kept together with an underpinning melody.

Finally, a solution for the nightmare flat cables in the SuperJX. After 30 years these cables are showing signs of the glue drying out and thus when unplugged for maintenance, they often fall apart especially if they have been abused before.
Humans by Luke Neptune
A fabulous new album by Luke Neptune that uses an enormous number of silky smooth sounds from the JX10 demonstrating it’s prowess in modern music.
You just don’t have this kind of bold lead synth playing in music anymore. Luke has done great service in what is contemporary yet draws it’s influence from the best of the past. Arguably this kind of playing and style had been lost in modern music.
Here is what Luke said about the synthesizers used on this album:
“….The JX10 is the star of the show of your fav track ‘I Can Make You Better’ It’s doing all the pads and strings and also the repeating saw tooth chord stab that comes in on the first middle 8. In fact that track is just JX10 and OB6. There’s JX10 on After Midnight (all pads). Also JX10 on Do It Now (layered with Juno 60, Ex5 and OB6 for a monster pad)….”
Check out video on YouTube for one of the great tracks on this album.
