This feature evokes the 90s vibe, allowing for real-time chord changes via sliders, making it suitable for both composition and live performance.\u003c\/p\u003e\n\u003cp\u003eThe following operations have been tested and confirmed to be in working order:\u003c\/p\u003e\n\u003cp\u003e・Sound output from all keys when connected to an amplifier.\u003c\/p\u003e\n\u003cp\u003e・Display contrast adjustment knob.\u003c\/p\u003e\n\u003cp\u003e・Pitch bend and modulation lever operation.\u003c\/p\u003e\n\u003cp\u003e・Floppy disk drive operation.\u003c\/p\u003e\n\u003cp\u003e・Various button and dial operations.\u003c\/p\u003e\n\u003cp\u003eUnlike some higher-end Roland synths from that era which suffered from melting weights under the keys, the JW-50, being a step below, does not have these weights and therefore has no such issues. The keybed offers decent velocity touch and includes aftertouch, though it requires some weight to engage.\u003c\/p\u003e\n\u003cp\u003eCosmetically, there is an impact mark on the side as shown in the 13th photo. The AC adapter plate also has an indentation, but this does not affect functionality. The soft case shows signs of wear. A formatted floppy disk is included as pictured.\u003c\/p\u003e\n\u003cp\u003eSpecifications:\u003c\/p\u003e\n\u003cp\u003eSound Engine:\u003c\/p\u003e\n\u003cp\u003e・Maximum Polyphony: 24 voices\u003c\/p\u003e\n\u003cp\u003e・Effects: Reverb, Chorus\u003c\/p\u003e\n\u003cp\u003e・Tones: Preset Tones: 128, User Tones: 128\u003c\/p\u003e\n\u003cp\u003e・GS Tones - Capital: 128, Variation: 61, MT-32: 128\u003c\/p\u003e\n\u003cp\u003e・Drum Sets: 9 + SFX Set (1)\u003c\/p\u003e\n\u003cp\u003eSequencer:\u003c\/p\u003e\n\u003cp\u003e・Internal Memory:\u003c\/p\u003e\n\u003cp\u003e・Note Capacity: Approx. 46,000 notes\u003c\/p\u003e\n\u003cp\u003e・Song Length: 999 bars, Songs: 8\u003c\/p\u003e\n\u003cp\u003e・Music Styles: 30 x 3\u003c\/p\u003e\n\u003cp\u003e・Preset Chord Changes: 30 x 3\u003c\/p\u003e\n\u003cp\u003e・User Chord Changes: 50\u003c\/p\u003e\n\u003cp\u003e・Blocks: 10 (A-J)\u003c\/p\u003e\n\u003cp\u003e・Disk:\u003c\/p\u003e\n\u003cp\u003e・Note Capacity: Approx. 80,000 notes\u003c\/p\u003e\n\u003cp\u003eOnly the items shown in the photos are included.
