Thank you for viewing. The pitch bend function sometimes malfunctioned, so I'm selling this because I bought a replacement. Please understand this before purchasing. I was using this until yesterday, so I've confirmed that the other functions work. The original box is not included. I will ship it with bubble wrap and cardboard. Purchased in March 2021. Thank you. ----- 61-key USB MIDI controller with programmable control knobs. - Brand: Nektar - Model Name: Impact GX61 - Number of Keys: 61 keys - Connectivity: USB - Features: Programmable control knobs - Application: MIDI controller - Size: Slim design
