Voice
HT generates 8 voices or DCO based on SD spectrum Dynamic synthesis, while drum section in based on PCM samples.
The 8 DCO voices are split into 2 parts:
- 4 for main part out of 31 waves
- 4 more for accompaniment part (reduced to 16 waveforms)
Wave
SD synthesis is a combination of 2 multipulses PCM waves, the combinated waves generate31 new cycled waves with altered harmonic contents and overtones.
Drum wavetbale
ROM contains 15 samples PCM waveforms at low resolution with pattern editor.
Filter
paraphonic analog lowpass filter with resonance (no self-oscillation).
LFO
a single modulator modulates only the DCO pitch with variable depth: It features a delay time parameter and 5 different waveforms: saw up, down, triangle, squanre and random
