Finding a faithful recreation requires looking for libraries that sample the original 114 internal "Original Tones". Notable sources include: D-70: Technical Specifications - Roland Corporation

Unlike its predecessor, the D-70 featured high-pass, low-pass, and band-pass resonant filters (TVF), which are often meticulously sampled in soundfont libraries to preserve their warmth.

A high-quality Roland D-70 soundfont brings the hardware's 3Mb of internal waveform ROM into the modern digital audio workstation (DAW). Key sonic characteristics include:

Famed presets like "Ghosties," "Prologue," and "SpaceDream" are hallmarks of Roland sound design, offering ethereal pads and punchy, "complete" textures that remain usable in modern production.

This experimental feature allowed for bizarre, metallic, and non-integral harmonic shifts, a precursor to wavetable synthesis. Authentic soundfonts often include these "weird and unfamiliar" DLM-based tones for unique sound design. Where to Find Roland D-70 Soundfonts
