The first truly portable analog synthesizer was released in 1971. Although it was rather pricey and could be temperamental, keyboard heavies of the era were quick to embrace it; and in the ensuing decades, its celebrated sounds graced countless concerts, records, and film scores. First off, the Behringer Poly D packs four voices of polyphony — instead of one — inside its classic, 37-key wood-trimmed chassis; and second — it is amazingly affordable! Otherwise, it packs all the features of the original — and then some.
