This is a Roland S-330 sampler. It has been in storage for a long time, and the exterior is generally sticky, but I have confirmed that it powers on and performs some basic operations. I have confirmed that there is audio output from the PHONES jack and that it responds to external operation from the MIDI IN jack. I have also confirmed that an image is output to a monitor by connecting an HDMI adapter to the RCA jacks. Operation on the screen using the dedicated mouse was also performed without any problems. Please note that the operations were performed by a layman while referring to the quick start guide, so I have not checked all the buttons and detailed functions. Therefore, please understand that there may be some minor defects and deterioration due to aging that have not been confirmed. *Included items* ・S-330 main unit ・Dedicated mouse ・System disk ・Two manuals Please understand that this is a used item in its current condition, and we ask for your cooperation in trading with no claims and no returns.
