Here we have a Yamaha EMT-10 AWM MIDI Sound Module (I actually have two to sell). It comes with the User's Guide and Power Supply. These units are considered 1/2U, which means they are 1 rack space high, but only 1/2 rack space wide. The outputs are phono (also referred to as RCA).
When the EMT-10 came out, they were referred to as Piano Expansion Modules, but they'll MIDI up to any type of controller, or serve as a sound module responding to MIDI sequence tracks from a computer, etc.
While some of the sounds are not as good as the new stuff these days, yet the "Strings" and "Choir "Aahs" are remarkable, and is why I bought them in the first place.
Call Tom at eight28-six93-nine867, and leave a message. If I'm home, I'll get back to you right away, otherwise . . . soon. It's just that I don't answer calls if I don't know who it is (too many solicitors). Or, you may email me through the "reply" button up top. Thanks for looking !!
