The D-70 can also split or layer the four tones that constitute a patch and has the same TVF filters used later in the JD-800.
It has four left control faders that can be assigned in real time to the following paramemeters: Level, Pan, Tuning, Cutoff, Resonance, Attack, and Release.
Despite being anticipated as a "Super D-50", it is in fact a different machine, a prototype of what would later become the JD-800 and the very successful JV series full-sample playback synths (ROMplers).
There are six reverbs (Room 1–3, Hall 1 & 2 and Gated), delay and cross-delay, and one effect from Chorus 1 & 2, FB-Chorus, Flanger and Short Delay in another effect.
Chorus / flanger allows you to set level, delay, rate, depth and feedback.
