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.

A Song For Guy – Thomas Östberg

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.

Thomas produces and plays keyboards for the band “Jolly Good” and “Benzin” based in Stockholm. Check out links to Benzin, Jolly Good and YouTube Channels Benzin, Jolly Good.

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’ :mrgreen: 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.

Midimuso create programmed integrated circuits to process MIDI messages and output voltages to integrate into your own electronic synthesizer projects or products without writing a single bit of embedded software. The devices are configured using MIDI messages and remember their configuration once set up. The manuals show a variety of simple circuits to get the very best out of them.

There are two types of programmed IC:

  • Flexible Composite Voltage Generation
  • Digital Oscillator with programmable waveforms

A Printed circuit board blank, kit or fully built is available to explore all the features of the CV-12 and build into your own projects and MIDI conversions.
