The Andromeda depends heavily on custom ICs that were designed by Alesis' former semiconductor division (which is now known as Wavefront Semiconductor). Alesis lost its ability to acquire more of these parts when its parent company, Numark, sold off the semiconductor division in 2003. After that point, Alesis continued to produce Andromedas using parts in stock. Production finally ended after the parts stocks were used up in 2009; in the last few years before this, production was done in periodic batch runs and customers often had to wait months for the next run before they could order one. Production estimates range from 1000-2000 units. The Andromeda retains high value in the collector's market, despite some doubts about the availability of spare parts; fortunately, most of the produced units (with the exception of some early-production units) have had good reliability. At time time it was discontinued, there were no other large polyphonic analog synths on the market, and many performers assumed that the Andromeda would be the last of its breed. But about six years later, Modal Electronics released new analog polyphonic models, and there has since been something of a revival of this genre of synth.
Most Andromedas have come equipped with a silver-white panel having blue highlights, as shown in the photo above. Some early production units (reportedly 20) had a silver-white panel with red highlights. Additionally, some third parties and users have made notable panel modifications.
