MU128

A 64-part, 128-voice polyphonic tone generator evolved from the MU100.
Major upgrades include doubling the height of the housing and adding a third slot for plug-in boards.
We also added buttons to the front panel for selecting voices by category, and provided a downloadable Version 2.0 update to make the MU128 compatible with the GM2 standard, which was released after the MU128.
