An approximation of the unusual, quirky Korg 800DV, or 'MaxiKorg', which Joe Vannelli and Richard Baker used to powerful effect (due to lots of laborious overdubbing) on brother Gino's "Storm at Sunup" and "Gist of the Gemini" albums.

The DV suffix stood for 'Dual Voice', due to it's two complete VCO/VCF/VCA 'synthlines', very much like most of Yamaha's CS-series synths.

Most of the functions are emulated, but not having an example of the real thing to compare to, I don't know how accurately - especially the 'Repeat' functions. Some feedback from DV owners would be greatly appreciated.

Some features/functions have been added or enhanced:

-Filter modulations are continuously variable, not switched.

-Envelopes expanded to full ADSR.

-A number of enhanced envelope controls and triggering.

-A few features from the Korg 770 incorporated (hence, the name '870DV').

-Layout of several panel controls put in much more logical order.


Changes to Version 2:

-Improved Filters and 'Alternative LPF' added, with quite different Resonance characteritics.

-Improved function of 'Repeat' section.

-Envelopes can be triggered by either LFO.

-Scale Noise level reduced to better match output of oscillators.

-Improved PWM ('Chorus').

-Added ability to select opposite channel in the Saw Mixers.

-Added MIDI CC# to Filter selector.

Be sure to save Version 1 to a separate folder if you've made presets for it.

This does NOT emulate or model the actual sound of any Korg or any other vintage hardware synth, just borrows from the control design, layout and panel design of the 800DV.

Be sure to click on the 'Notes' button at the panel's upper right for more info on the rather unusual controls and functions.


32-bit, so will require jBridge, etc., (or a DAW that will bridge) for use on 64-bit systems.

The link on the website is to a Sync.com folder that also contains the .osm Synthmaker source 'schematics', so anyone with Synthmaker or Flowstone can alter it to suit. It's hoped that anyone who makes significant improvements will share the result with everyone.

As this was originally built for my own use only, there are no presets included; I wanted to come at the instrument anew each time, as one did with vintage analog hardware.
