The Yamaha AN1x is a virtual analog synthesizer introduced in 1997, featuring 10-note polyphony and dual oscillators with various waveforms. It is known for its physical modeling capabilities, allowing for complex sound design and real-time control through its unique interface and features like scene memory and a ribbon controller. This is a highly sought after underrated unit that has rich analog sounds associated with the Prophet series with deep sculpting capability.
Everything works but there are definitely some small cosmetic scratches that don't affect the unit. (shown on photo) Keybed is perfect. Comes with the power supply and can be used with sysex to upload new patches. Many 3rd party sound packs are available.
This synth legend offers free patches if you can use the sysex software:
