"The HT-6000 introduced for the HT line some of the more high-end features, such as ring-modulation, detuning, key-follow, and initial-touch.
The HT-6000 used an impressive 4 DCO's per voice.
It had 64 DCO wave forms to choose from (32 basic, 16 with noise [white or metallic], and 16 with ring modulation). It had 8 independent VCF filters , and added key-follow parameters for both the DCA and VCF. The DCA also added attack and decay curves (acute and obtuse). It also added an independent ADSR envelope for noise. The 4 DCO's each use the same waveform, VCF and DCA envelopes, but can have separate tunings, velocity response curves, and relative DCA envelope depths. Stacking the oscillators with detunes allowed the creation of flange and chorus effects, fat "super saws", and the creation of dual-note or even triad and 4-note leads. The filter cutoffs could be set to respond to velocity which added some expressiveness. Because each oscillator could have separate tuning and velocity response, it was also possible to have the pitch change according to pressure, if one of two differently tuned oscillators had an inverse velocity curve. Ring modulation used ocsillator 4 to modulate oscillator 3, and allowed the creation of metallic and pulse sounds, lower bass harmonics and even distortion."
