VCF, Drums and Others
VCF
While other HZ/HTs have only one VCF for a channel, HT-6000 has 8 VCF - one VCF per each voice.
VCF became fully polyphonic and independent. When a new note played, other sustained notes are not influenced.
Key follow function is also added.

Drums and Auto-Accompaniment
Drums are basically similar to other HT. They use 8-bit PCM and resembles CASIO RZ-1 drum machine.
Reflecting the late 80s atmosphere, Gated Snare, Timpani and Orchestra Hit are added.
Preset DISCO2
HT's Auto-Accompaniment uses the Lower Tone for Chords and has a monophonic Bass sound.
HT-6000 has one more part, 'Obligato.'
Lower Tone is editable and consists of 2 DCOs and Noise. There is no ring modulator.
Bass and Obligato sounds can't be edited.
Make a new sound and hold some keys, then HT-6000 starts playing.

Comments
There are some disadvantages. SysEx is not supported and key range is only 5 octaves.
But 4DCO architecture with ring modulator made HT-6000 a great synth.
It is the only DCO analog synth that has as many as 32 oscillators,
and it even surpasses Roland Super JX in this respect, which has 24 DCOs.
Oscillator-to-oscillator modulation is now relatively rare in the synth market, except some Roland, KAWAI and virtual analogs.
Without such functions, a synth's ability would be significantly limited.
HT-6000 is an unexpectedly evolved half-but-really-analog synth.
It seems to be one of the last DCO analog.
It was not so long before analog began appealing to people again.
If only CASIO waited a bit longer, the advanced SD synthesis might have had its day.
