This is a Roland JV-2080 sound module with 8 expansion slots. Software synthesizers have become the main focus recently, and since hardware takes up space, I am putting this up for sale. Two expansion boards are installed. (They have been installed since I purchased it) * Piano * Orchestral The unit functions without any problems, but it is an older model, so there is some deterioration due to age. The instruction manual is also included, but it is discolored and shows signs of wear. I would appreciate it if you could understand the above points before bidding. Price negotiations are also welcome. Thank you for your consideration.
