Korg DW-6000
Cable and MIDI requirements
The Korg DW6000 uses a standard MIDI cable, Parameter 81 needs to be set to the same
channel number that is programmed into the Patch Editor for the DW-6000 or Parameter 83 can
be set to Omni. Parameter 82 needs to be set to 2 to enable SysEx control.

Korg DW-6000 Notes
The DW-6000 uses two separate voice generators which are not VCOs but rather are preprogrammed wave form
generators which change their frequency depending on the note played. The waveforms are generated from
ROM (Read Only Memory) look up tables and the frequencies are calculated in real time by very fast hardware
multipliers and a DAC (Digital to Analog Converter) to produce the final waveform. When you think that this
system is calculating complex waveforms for 12 separate waveforms simultaneously (up to 6 notes with 2
oscillators each) all in real time it is fairly impressive. A more conventional filter and VCA is used which uses the
NJM2069 combo chip for each of the 6 voices.
The Korg DW-6000 uses a complex system of combining controls as there is a limited memory available within
the DW-6000. This makes it a difficult synthesizer to control using standard SysEx controllers. The Patch Editor
handles the combining of controls invisibly. Because of this combining, changing one control in a combination
will also set the other part to the current Patch Editor setting. This is unavoidable due to the way the DW-6000 is
controlled. Combinations are
1) Oscillator 1 Range & VCA Env Release
2) Oscillator 2 Range & LFO Rate
3) Filter Key Modulation & LFO Delay
4) Filter LFO Modulation & Chorus Mode
5) Oscillator 1 & Oscillator 2 Waveforms
6) Oscillator 2 Tune & Fine Tune
7) Filter Bend (not used) & VCA Env Sustain
8) Oscillator 1 LFO Mod & Polarity
The oscillators 1 and 2 Range buttons are used to step through all possible octaves. These are 16', 8' and 4'.
The oscillators 1 and 2 Wave buttons are used to step though all possible programmed wave types. These are
Brass, Violin, Acoustic Piano, Electric Piano, Synth Bass, Saxophone, Clavicord and Bell.
The Oscillator 2 tune will change the oscillator 1 and 2 interval. Possible interval options are unison (same as
Oscillator 1) , minor 3rd, major 3rd, perfect 4th and perfect 5th. The Fine Tune control on the Patch Editor will
provide Oscillator 2 Detune.
The Oscillator 1 LFO modulation control will effect both oscillators 1 and 2.
The Filter Keyboard Track has three possible levels, Off, 50% and 100% and the Filter Mode button will invert the
filter envelope. Green is a normal envelope and red is inverted.
The Envelopes in the DW-6000 use extra controls. In addition to Attack, Decay, Sustain and Release there are
break level and slope controls. The Patch Editor sets the slope equal to the decay and the break level equal to
the sustain which has the effect of changing the envelope generators to the four control system.
