DCO and Line Edit
DCO
Oddly enough, HT-6000's manual says nothing about SD - Spectrum Dynamic synthesis,
though obviously, HT-6000 is an extensively advanced version of HZ/HT, the SD synths.
SD seems to use what I call additive pulse wave synthesis, which combines several pulse waves in different widths,
with various amp envelopes.
For details about SD oscillator, see HT/HZ page.
There are 64 waveform settings, grouped in two, for HT-6000's DCO.
Group 1
There are 32 SD waveforms including quasi-saw, square and various pulse waves with sometimes metallic timbre.
Some waves has SD's characteristic temporal motion.

Group 2
Wave 0-15 in Group 2 are SD waves combined with a noise oscillator.
Wave 16-31 are SD waves with a ring modulator added.
Line Edit
HT-6000 has 4 'Lines.'
A Line roughly means an oscillator, and HT-6000 is actually a 4-DCO synth.
But the same waveform is assigned to all the four Lines.
If you select saw wave, all the 4 DCOs share saw waves.
Detune, amplitude and velocity curve can be set individually for each Lines.
Lines can be detuned only higher than the fundamental.
CASIO recommends using this as something like additive synthesis.
Using 4 Lines, unison or 'Super Saw' sounds can be easily made.
4 Saw waves stacked with no effects
Preset No. 1 is 'Synth-Ens1,' not 'Piano,' which is an appropriate choice.
Stacking 4 DCOs combined with VCF, it can generate typical analog synth sounds.
