Boss DR-220 Drum Machine 1985 - Pre Owned
£150.00
The DR-220 derives from the earlier DR-110 (1983) without rotary controls but the same LCD "matrix" display panel, a much simplified version of that used in devices such as the Roland TR-707.
Each DR-220 has 11 pulse-code modulation (PCM) synthesizer "voices" available, plus an Accent; each voice is directly available for realtime play using the four-by-three grid of miniature pads (though these do not sense either velocity or pressure). The voices are in 12-bit resolution, each occupying a 128 KB Read-only memory (ROM) bank. Because of "channel sharing" restrictions due to circuitry limitations, some voices cannot be sounded simultaneously; for instance, only one tom may be used per beat. With the DR-220, up to 16 steps are displayed (or 12 in 3/4 tempo mode). The "hits" can be displayed only one pad at a time. A pattern can be recorded in realtime, or entered step-by-step. Each voice can be adjusted for Accent (values 0-5) and volume (values 0-5).
