The Baldwin Discoverer DS-50 is a portable analog organ and rhythm machine originally manufactured in Japan by Brother Industries as the Brother Auto Emillion GX-151 before being licensed and sold in the United States by Baldwin.

Works great. Includes Brother branded carrying bag with strap and power cord.

Features:

• 49 full-size keys.
• 8 basic, preset rhythms with analog drum sounds.
• Arpeggiator/auto-accompaniment. With the two front buttons, you can choose major (no button, minor, minor 7 (eg E7) or minor with minor 7 (both buttons) (eg. Em7).
• 3 cheesy preset sounds or a slider (cancel) section which allows you to blend four "solo" voices which are full sustain, organ-type sounds (flute 8', flute 4', oboe, violin).
• Vibrato effect amount slider.
• "Sustain" (actually release) amount knob.
• Programmable chord sequencer.
• Mono 1/4", RCA and headphone jacks, a microphone input, and a 4-ohm speaker output.
• Runs on 120V AC or 12V DC (positive center) adapter.

Though built as a consumer/educational home instrument, it features a sturdy metal chassis and a warm retro analog tone. It has gained a cult following and collector status, reportedly finding favor with notable artists like Brian Wilson, Radiohead (used on In Rainbows) and Gorillaz.
