Time sale! Price negotiations are welcome! (Within reasonable limits!) This is a 49-key MIDI keyboard with blue LED backlights and control knobs. - Model Name: KOMPLETE KONTROL S49 - Keyboard Type: MIDI Keyboard - LED Light: Blue LED Backlight - Number of Keys: 49 keys - Control Knobs: Multiple control knobs *Sometimes the power connection is poor. (It was good in the photo) Recommended for those with knowledge of the equipment or those who don't mind! Also, I will include one long USB cable. *Since it is a MIDI keyboard, it does not produce sound on its own, so sound will only be produced when connected to a PC, Mac, or modular synth, etc.! Price negotiations are also accepted (within a reasonable range). Thank you very much! Thank you for viewing. #midikeyboard #NativeInstruments #komplete #keyboard #dtm #musicproduction
