Time machine: ROLAND D-70 Digital Synthesizer 1990
Taking a closer look at the vintage synth Roland D-70, video details below:
I played the Roland D-70 without any additional effects or eq. All you hear is coming straight out of the Roland D-70.
The fully digital Roland D-70 employs a LA (Linear Arithmetic) sound engine. It contains samples which can be filtered with lowpass/bandpass/highpass filters. The oscillators can be modulated via DLM (differential loop modulation). This can produce weird sounds, like heard in the video. A pity, that the JD-800 does not have this feature. It also has a multi effect processor built in (reverb, chorus, delay…). It has TONE PALLETE sliders, which help a lot to tweak the sounds.
In my opinion, the D-70 is more a “live performance synth” than a studio synthesizer. That’s the reason why a rack version never appeared.
The D-70 is very complex. But not exactly the synthesis engine – rather the performance functions: splits, MIDI functions, controller maps, master keyboard functions and that sort of things…. but I must admit, sometimes it sounds beautiful.
It was used by Michael Cretu (Enigma, Sandra).
