D 70

TheRoland D-70is a 76 noteSuper LAsynthesizer produced in Japan in 1990. it featured a240 × 64pixel backlitLCDdisplayand competed with the likes of theKorg M1and T-series workstations and Yamaha SY77 workstation, although the D-70 was not itself a workstation because it lacked a sequencer. The D-70 can also split or layer the four tones that constitute a patch and has the same TVF filters used later in theJD-800. It has onboard drums sounds and is 6-part multi timbral (5 synth parts and one drum part). 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. It has three modes of play: Mono, Polyphonic, Split. Despite being anticipated as a "Super D-50", it is in fact a different machine, a prototype of what would later become theJD-800and the very successful JV series full-sample playback synths (ROMplers).
