The instrument
The EP-6060, which was one of the last analogue instruments to be launched by Roland, is a dual voice piano with two sets of oscillators, tone shapers and pitch controls. This doubling results in a smoother sound, especially when the oscillator sets are slightly out of tune with each other. Like the earlier EPs, the piano has a 6-band equaliser.
Details
The five-octave C-to-C keyboard is artificially weighted. There are three tuning options for each half of the piano: soft, semi-bright and bright piano. Two or three voices can be played simultaneously. Each half has its own decay control and footage selector: 16 and 8 on one side, 16, 8 and 5⅓ on the other. The arpeggiator uses the technology of Roland's drum machines to add rhythm. There are also chorus and four beat patterns that provide four, eight or 12 beats per bar, or even a variant that moves the arpeggio to triple/quarter time.
The equaliser sliders are at 100Hz, 200Hz, 400Hz, 800Hz, 1.6kHz and 3.2kHz to boost highs or lows and suppress unwanted frequencies. (Roland Manual)
