New Sounds For The Korg Prologue From Jexus

Sound designer Jexus shared this no talking demo of the Korg Prologue synthesizer.

The video demos a collection 200 custom patches by Jexus for the Korg Prologue, but it’s also a good showcase of the synth’s sound design possibilities.

Here’s what Jexus has to say about the demo:

“I did not use any external FX in the demo; all the delays, phasers, noises and other effects are part of the Prologue engine & my intentional patch design. I did not use the onboard LF Comp but I used some slight EQing on some patches. I recorded my demo straight through an audio card.

This is a standard factory Prologue unit – you don’t need any custom oscillators, FX or other addons (just the factory „Waves” oscillator).”

  1. Seriously? The sounds remind me of what my 3 year old son was getting when he randomly played with the knobs on my MiniMoog some 40 years ago! People pay for pathetic material such as this?

  2. Disagree. Jexus brings out more of a synth’s range than anyone else I can name. Give his YouTube channel a look. Pretty patches are fairly easy. Patches that show off the real muscle are a different thing. Even if you only use his set as leaping-off points, its still money well spent. His programming imagination is huge.

    1. Just checked out his YT channel, lots of good stuff. His MS2000 videos kind of made me regret selling my keyboard version but I still have my rack version, may unbox it and play with it.

  3. Prologue’s strength is in the user oscillator, and 16 voices. although Waves was pretty dull – I prefer Plaits and Elements models on mine – custom modified for more fun; I love mine.

    However, packed with with 19 ARM CPU’s, I don’t expect to see them on production for a looooooong time if ever; it never garnered much acclaim. folks only looked at it as just another analog – what a waste of a unique synth.

    1. The Korg Prologue is like a modern vintage synth. The build and controls feel old school and easy to figure out. Just about everything is right there on the front panel.

      The user oscillators and effects open up a whole world of possibilities that go beyond analog, though. Korg dropped the ball not promoting this more, but the possibilities are pretty amazing. You can load up open source Mutable Instruments oscillators, great free reverbs from hammondeggs, and commercial stuff from Sinevibes and others.

      I’d like to see a ‘Prologue Deluxe’, with more performance control, deeper modulation options and an audio input.

      1. it’s become the only keyboard I play; the sounds are endless if you put the time in – 16 channels of programmable oscillators and effects mains? no brainer!

        there would be a lot of things to improve upon in a 2.0/Deluxe, but I don’t see it happening; unless CPU’s are going to be free flowing and dirt cheap in the aftermath.

  4. Prologue is good, but its more outdated, more modern version is XD.
    Why Korg not update ProLogue to XD possibilities? Just add to XD additional voices)

    1. disagree. Prologue is a players synth, XD is a programmers synth. I’ve had an XD, I wouldn’t use any of it’s features in a Prologue format – I would prefer many other Prologue enhancements first; more digital memory, CPU, and control inputs for more complicated user modulations; more effects resources for three effects stages and no interoperability problems with CPU utilization; better MIDI stack handling during program changes – my LFE drives Prologue bonkers unless I delay MIDI transfers until user oscillator loads (can be as much as 5 seconds for 32Kbyte osc’s); finally better linkages between digital and analog subsystems including velocity, AT, working filter inputs, etc…
