OSCILLATORS  intel 16 bits CPU 8097BH manages 32 voices (DAC PCM54HP BB) polyphony or partial (a patch is composed by up to 4 partial); each partial being either a synth waveform (saw tooth or square with variable width) or any one of the internal 256 PCM samples. Finally Each pair of partials (1&2 and 3&4) an be assigned a Structure (13 models, see below).

PCM The sample PCM are divided into two banks, each with 128 samples.
PCM A: transient attacks (The attack samples concentrate on providing the attack envelope segments of behavior of instruments. )
PCM B:  same as A but in looped form. 
NOTE: 63 samples are dedicated to drums and percussion

SOUND HIERARCHY "The D-110 can produce a maximum of 32 voices using 32 Partials at the same time, A partial is the smallest unit of sound within the. D-110. A Tone consists of one to four Partials. A Tone made of only  one Partial can be played 32 voice polyphonically, but a Tone Of two  Partials has 16 voices, and a Tone of four Partials is 8 voice polyphonic" very complicated. Rackmount is even worst! not intuitive at first try with few logic.
