Unlock the creative depth of your Roland D-50 or D-550 with this original Roland PG-1000 programmer, offered in excellent condition. Designed specifically for these classic LA synthesizers, the PG-1000 brings sound design onto a clearly organized panel with 56 physical sliders, making it far easier to explore the instrument’s synthesis engine and shape sounds with intention. Adjust tonal character, filters, envelopes, modulation, and the relationships between partials as you develop anything from subtle variations on favorite presets to entirely new voices. Its dedicated controls make the architecture easier to understand and encourage experimentation—the kind that leads to a sound you might never discover through menu editing alone. For a D-50 owner who wants to move deeper into programming, or a collector assembling an original Roland setup, the PG-1000 is an especially desirable companion. It combines practical creative value with the visual appeal of a purpose-built vintage programmer. Please review the photographs of the actual unit offered. This listing is for the PG-1000 programmer only; the synthesizer and sound cards are sold separately. The PG-1000 requires a compatible synthesizer to produce sound.
