This item was purchased a long time ago because I wanted to use Delay Lama without a computer. It allows you to use VST sound sources without a computer. When I obtained it used from overseas, support from SM PRO AUDIO had already ended, but there seem to be enthusiastic users, and an unofficial support page still exists. I have not tested installing the software on Windows 11 for the purpose of selling it, so please keep that in mind. Regarding standalone operation, I confirmed that it can produce sound and the buttons function correctly when connected to a Launchkey 37 via USB, but I have not confirmed whether all terminals are functioning properly. Also, although the box is damaged, the main unit is relatively clean. Please understand these points before purchasing. Included items: Main unit, AC adapter (genuine), USB cable, 2 DVDs (Getting Started, IK Multimedia Sampletank 2 SE), Manual DAW, VST, Standalone, Hardware
