Akai MX73 73 key MIDI Master Keyboard MIDI Controller mx-73 Fully Working & Tested

This is an extremely nice master keyboard to play on. Please note the complete lack of yellowed plastic!

It has internal patch memory, several sliders to send basic MIDI controls to other synths, TEN dedicated pedal inputs, etc. The screen is working fine as well. All buttons work great and are responsive, and all keys work perfectly. There is a very minor dent next to the top-right corner of the control panel section. Has many cool features to help you adjust the note range of the keyboard, etc.

"73-key 4-split function for controlling multiple sound sources With the MX73, four MIDI sending channels can be set simultaneously and key note ranges and octave shifts can be assigned to the channels individually, permitting control of up to 4 different sound sources. The wide key range and velocity sensitive keyboard make for excellent multisplit playability.
Remote function for assigning random MIDI control changes with four sliders and switches The four sliders and four switches on the operation board can be used to assign MIDI control changes [00-311 and [69~ respectively. This remote function makes it possible to change the values of the sound source's main volume, data entry, portamento time, modulation wheel, etc., as well as to turn such things as chorus, portamento, and sustain on and off. The sliders and switches can be controlled by a foot control or foot switch, great for system control during live performances.
Superior playability with a 100-program memory There are four areas (I-IV) for each program, and all of the following parameters and functional data can be sent to the MIDI outputs for these four: MIDI channel, split point, octave shift, bend select, wheel select, poly/mono select, omni on/off, control switch select, control select, program change number, sustain pedal select, key velocity sensitivity, and MIDI messages (control change) assigned to the four sliders and switches. The internal memory has a large capacity (100 programs), and tape interface can be used to save, verify, and load all programs at once or one bank at a time."
