Sinevibes Dense Brings Vintage Oscillator Sound To The Korg Prologue, Minilogue XD & NTS-1

Korg Multi-engine gurus Sinevibes has introduced Dense, a new custom oscillator for the Prologue, Minilogue XD and NTS-1.

Dense is a vintage virtual analog oscillator Multi-engine plugin that features four separate oscillators with saw, square, triangle waveforms. In addition to mutual detuning, each oscillator has its own random pitch drift LFO, and global pitch can also be slightly off on every key press. Together, these features simulate tuning instabilities and per-voice discrepancies of old analog synthesizers, ranging from very subtle to “badly needs calibration”.’

Dense includes a total of 50 sound source configurations, with different settings for individual oscillator parameters such as waveform, coarse tune, output level, as well as optional ring modulation or bit depth reduction for an even wider sonic palette.

Sinevibes says that, as a result of the various fluctuations and dynamic interactions happening between the oscillators, as well as between the oscillators and the synthesizer’s filter, Dense can produce beautiful vintage-style sounds that are full of life and organic movement.

Dense Preset Demos:


  • Four virtual analog oscillators with saw, square, and triangle waveforms
  • 50 oscillator configurations featuring different settings for waveforms, coarse tune, fine detune range, output level, ring modulation, and bit depth reduction
  • Four random modulation generators (one per oscillator) for simulating vintage analog-style pitch drift
  • Adjustable key pitch randomization for simulating vintage synthesizer tuning discrepancies between multiple voices
  • Adjustable one-pole high-pass filter with cutoff frequency key tracking
  • Built-in sine LFO for additional global pitch modulation
  • Built-in lag filters for noise-free, ultra-smooth parameter adjustment and modulation

Pricing and Availability:

Sinevibes Dense is available now for $29 USD.

  1. It’s kind of funny, don’t you think, that a Prologue and Minilogue would need a digital oscillator to sound “analog”? However, this kind of makes my main point concerning “VST in a box” synths. BTW, before somebody accuses me of being a Korg or Prologue hater. I have a Prologue and, even without this oscillator, I consider it to be one of the better “analog” synths. Certainly sounds more “anaog” to me than does my Prophet 6.

    1. i love my prologue 16. i love sinvibes work too! unfortunately, I have 13 slots stuffed with my own work and the other three are already filed with sinvibes osc’s :0) almost all my effects slots are sinvibes. my favorites are physical modeling oscillators and wavetables, although it’s a tight fit to do much in 32k shared I+D space. and the SDK wavetables are too tame. I would get this as well, but what to bump? I need another Prologue! that’s it!

      I don’t use it much as an analog voicing, i prefer the variety of digital harmonics mixed with triangle to fatten up the fundamental stuff into the analog filter. the post-filter overdrive also has a very distinctive sound. I’ll even use moderate Q’s.

      so, John, question for you. how do you feel about the complexity of the Prologues user oscillator parameter space when compressing a multiplicity of voicing configurations into cardinal number series like you see here? roll log also had a multi-modal config-index on some oscillators; Fume, Syng, Wave-thingy. I’ve come up with some pretty horrific menu-ing system, but prefer more simple control expressions. I had to have a sheaf of cheat sheets before I started just doing my own menus and modulation structure, and settled on a unified control expression for all oscillators. makes it much easier. also, pro tip SHIFT also work on the menu system, so you can go backwardson parameter programming if you miss a param.

      1. “John, question for you. how do you feel about the complexity of the Prologues user oscillator parameter space when compressing a multiplicity of voicing configurations into cardinal number series like you see here?”. Unfortunately, I really can’t answer that question right now. I have only had my Prologue for about six weeks, or so, and with all of the other things driving my time I haven’t had much of a chance to play with the digital oscillator. The semester ends for me next week and I hope to get more time playing with the digital oscillator on the Prologue. Seriously, I really like the Prologue, and I find some of the factory presets that make use of the digital oscillator to be outstanding.

    2. Most Synths today are VST in a box, for sure. The interest and usability of having this modeling oscillator is given when both are combined. It not possible morph and VCO into other thing than be and VCO, so for this type of situation it is interesting to have this type of oscillators.

  2. Not being a Prologue owner, the question is this: Does this add 4 VA oscillators per note, in addition to the 2 real VCOs, or is it 4 note polyphonic?

    1. Neither. Prologue has 8 or 16 voices (depending on the model), each consisting of 2 analogue and one digital oscillator. This does not change the total number of voices or oscillators, it is just a digital oscillator model that you can load instead of the digital oscillator that Prologue comes with.

  3. Adding analogue oscillators to a synth that already has analogue oscillators is a bit odd!

    When I was coding my own plug-ins for the Prologue, I did the opposite, trying to build very digital oscillators that complemented the analogue ones. (ie: airy breath sounds, FM harmonics etc. with a built-in HPF).

    1. That’s exactly what I thought when I read the tag line. When I purchased my Prologue 8, my main reason for doing so was that malleable digital oscillator slot. Then, much to my surprise, I found myself liking the out-of-the-box “analog” sound of the device much better than even my Prophet 6. I will probably never design by own oscillator for the Prologue, but the ones I have either purchased or downloaded have been digital things (for the reasons you mention). However, after hearing the sounds on the video, I’m starting to re-evaluate what is actually implied by the term “analog sound” when it comes to synths.
