I am selling an AKAI MPC Key 37. I purchased it on July 22, 2024, and have only used it lightly about three times, for 30 minutes to an hour each time. There is no degradation such as hydrolysis, and it is in very clean condition overall. The pads are made of a material that tends to attract dust, but they can be easily cleaned with a cleaner. All accessories, such as the original box and instruction manual, are included, and I will provide them as they were when purchased. I bought it to try out the AKAI workflow, but it didn't suit my production style, so I am selling it. I have confirmed that it works and can be used without any problems. I have kept it in good condition, so I would like to sell it to someone who will appreciate it. Regarding licenses, I have confirmed with official support. The hardware deactivation procedure is not required, and the license will automatically transfer when the new owner registers the product to their inMusic/Akai Pro account. Of course, I will hand over the unit after it has already been removed from my account, so you can use it with peace of mind.
