Critic Reviews

Proteus One (MIC Mar 90)

muzines.co.uk

The E-Mu Proteus 1 offers impressive sound quality with its 16-bit samples and extensive patch library, appealing to those seeking rich and varied tones. However, its lackluster build, limited editing capabilities, and absence of built-in effects like reverb and delay might deter those expecting a complete package for its price. If pure sound quality is your priority, it merits consideration, but expect to complement it with external gear to fill in the gaps.

50% gold, 50% fools!

I'm going to start by saying that if you've ever used digital recreations of the Proteus series, you're missing out. The soundfont files for the Proteus lines that are floating around are really inaccurate and sound really bad, and various digital recreations are inaccurate in one way or the other. You won't get anything good, unless you get the real deal.

That being said, this is a fun little synth with a cute set of sounds, I picked mine up earlier this year, and while I've not used it much for actual production, the playing around I've done with it has been quite a treat as I find it to be very fun to fiddle with and see what patches I can mix together to get really cool sounds, plus this thing sounds cool on its own despite having no onboard EFX, no clue how they pulled it off but the 'fakery' they do for simulating things like reverb trails on strings is smart and well done.

Great write-up :) So sample sets made from the original equipment won't do this thing justice?

Nothing to rave about, but it changed an industry when it came out

Quoted from Vintagesynth.com

http://www.vintagesynth.com/emu/proteus.php

Throughout the 1990’s, E-mu came to be known for its rack-mounted synth and sampler modules. In 1989, the Proteus was the first rack-mount module E-mu produced, and it was a huge success for the company. The Proteus 1 is an economical one-space module consisting of your basic rock and pop sounds. It has 4 MB of sounds from the EIII library such as samples of pianos, organs, strings, horns, guitars, basses, drums, Latin percussion, and more all at your fingertips. The Proteus offers professional features such as full 16-part MIDI multitimbrality, 32-voice polyphony, 16-bit ROM samples, six individual polyphonic outputs and extensive editing and modulation capabilities. There is also E-mu's RMidiPatchS that allows direct real-time control of over 40 parameters for keyboard, midi controllers, internal LFOs and envelopes. It has been used by Astral Projection, Pet Shop Boys, Vangelis, Genesis, and Information Society.
