First of 3 part video on the Roland D70. First part is a survey of sounds illustrating the acoustic and synth wave form samples. The D70 is an under-rated synth. With 30-voice polyphony, 76-keys, acoustic, analog, and digital waveform samples, and up to 4 tones per patch--either layered or zoned across the keyboard--it provides a lot more sound possibilities than other classic synths at a fraction of the cost on today’s used market.
