61-key MIDI keyboard with 8 knobs and 16 pads. I was using it with CUBASE until recently. During live performances, I connected a MIDI cable to a sound module and played. I tested its operation again for this listing. I checked the MIDI channels and program changes using the numeric keypad. It works without any problems. Octave changes also work fine. The main features of this unit are its slightly heavy touch and the numeric keypad. While many MIDI keyboards use keys to change sounds, this unit allows you to change sounds with the numeric keypad. Also, the power supply is 9V center-positive and USB. The unit is lightweight and has a good touch, making it easy to use, and I found it very useful. I will include a YAMAHA soft case, a USB cable, and a MIDI cable, all about 3 meters long.
