Used E-MU UltraProteus rack mount synthesizer, from home studio where all equipment was kept in excellent condition. Unit never left the house. Includes power cord and original manual. See photos for specs.
The UltraProteus contains 16 megabytes of pop, rock, orchestral and world samples from the Proteus family of instruments. In addition, it includes drum sounds, waveforms, and the Proformance stereo grand piano. The 16 bit sound samples are arranged into 256 preset locations, 128 of which are user programmable.
Sounds can be combined or spliced, modulated and then shaped using one of 288 Z-Plane filters. The Z-Plane filter has the ability to smoothly change its function over time, and can accurately simulate the resonance of instruments or voice, or create entriely new timbres. The Z-Plane filter is composed of up to eight complex filters for control over subtle aspects of sound. The Z-Plane filters are categorized into groups of: flangers, vowel filters, traditional filters, parametric filters, instrument models, etc.
UltraProteus features two studio-quality effects processors with 28 different effects to choose from . You can have up to 32 different sounds on your keyboard at one time in any arrangement, placed side by side or layered with velocity control. The UltraProteus has the ability to respond multitimbrally to all 16 MIDI channels, making it ideal for multitrack sequencing and composing using a MIDI sequencer.
Other features include 3 stereo outputs for individually processing sounds, integral sends and returns to allow the addition of external effects, user definable alternate tuning, and extensive MIDI implementation.
