(KORG) TR-RACK Sound Module Synthesizer Sound Source Hardware Synthesizer

This is a 1U rack sound module from KORG's TRINITY series. It's a rare hardware sound source that's hard to come by these days, wouldn't you agree?
Recently, I've been hearing from colleagues who work in sound production that old hardware sound sources have a richer sound than software, and that hardware is being re-evaluated and is quite popular.
That reminded me that I might have an Alesis D4 or DM5 somewhere, and while searching for it, I found this KORG TR-RACK, so I'm putting it up for sale.

Back in the day, from the Mac OS 8 era, I was obsessed with DTM using Vision and collected various equipment. However, after the birth of my first child, I couldn't find the time and put it away.

I don't recall using this unit much, so I've done a quick check of the display, buttons, and ports, and I believe the condition is good from my perspective. However, this is not a professional check, so please refrain from purchasing if you are sensitive about such things.
I would appreciate it if you understand that this is a used item and agree to no claims and no returns.
- Instruction manual included
- Original box not included.

I hope to pass this on to someone who loves KORG's rich sound, whether for hobbies or work, or who loves synthesizers, and who will use it carefully for DTM, DAW, music production, etc.
