E-MU Proteus 2000 Purchased new about 20 years ago and used indoors ever since. Like many units, the dial is not working well, making it difficult to select presets using the dial. There are no problems using it via MIDI. Power and sound output were also confirmed to be working. Includes power cable and rack mount brackets. It has a thick and easy-to-use sound, befitting its reputation as a classic. The sounds blend very well with other instruments and were easy to mix. Selling to organize my equipment. Feel free to ask about price reductions. Thank you. #SoundModule #Synthesizer
