The Roland MX-1 is an 8-channel multi-track mixer. It supports USB and MIDI connections, making it very convenient for connecting with the company's Boutique series and AIRA series. - Brand: Roland - Model Name: MX-1 - Function: Multi-track mixer - Connectivity: USB, MIDI, TRS - LED Indicators: Blue, Green - Number of Control Knobs: 8 - Number of Faders: 8 - Display: LED Display - Power: AC Adapter There is a dent above the logo in one place, but otherwise, I think it's in very good condition. I recently purchased it as a used, beautiful item at a musical instrument store, and I don't smoke. I felt that it was becoming increasingly difficult to obtain, so I bought it, but I've decided to sell my TR-8 and other equipment, so I'm putting it up for sale. Thank you for looking.
