The HT-6000 was reviewed in Keyboard Magazine, November 1988, p. The HT-6000 was also sold in Germany by Hohner as the KS-610/TR. In terms of 'home keyboard' features the HT-6000 improved the auto-accompaniment versus the previous HT's by including some additional PCM drum sounds, an additional accompaniment part ('obbligato'), 4 bass patches (versus one), additional chord inversions (including more tonic, suspended and subdominant triads), and the addition of 'Intro' and drum and chord 'Variation' for auto-rhythms. Like the HZ-600 but unlike the others, the HT-6000 had a complete parameter list silkscreened on the outer panel, somewhat alleviating the need for a manual.

Ring modulation used ocsillator 4 to modulate oscillator 3, and allowed the creation of metallic and pulse sounds, lower bass harmonics and even distortion. 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. The filter cutoffs could be set to respond to velocity which added some expressiveness. 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 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. It also added an independent ADSR envelope for noise. The DCA also added attack and decay curves (acute and obtuse). 1 per channel), and added key-follow parameters for both the DCA and VCF. Analog Chords 3 - Casio HT-6000 by ShamanStems published on An extremely rare and underrated synth, 1987 built Casio HT-6000 has the specs of legendary analog synths: 8 voice polyphony, 4 oscillators, 64 different waveforms, resonant analogue filter, analogue chorus, ring modulation, white noise, multitimbrality and the. It had 8 independent VCF filters (1 per voice, vs. It had 64 DCO wave forms to choose from (32 basic, 16 with noise, and 16 with ring modulation). 1 on the other SD synths, and 2 on the CZ synths). The HT-6000 used an impressive 4 DCO's per voice (vs. The HT-6000 introduced for the HT line some of the more high-end features previously only included by Casio in the CZ line, such as ring-modulation, detuning, key-follow, and initial-touch (which, among the CZ's, was only found on the most advanced model, the CZ-1). While designed as a consumer model, it was far more powerful than the more professional-appearing HZ-600 whose synthesis engine the other HT's utilized. The HT-6000, released in late 1987 but not widely availabile until late 1988, was an entirely different SD synthesizer which greatly expanded SD the synthesis engine.
