The E-MU Proteus/1 Plus Orchestral or Proteus/1+2 XR, is a variant of the Proteus/1 XR made by E-MU in 1992 that features their Plus Orchestral ROM Expansion built into the module. This makes the Proteus/1 not only have an extra 192 presets for being an XR model, but also has 128 ROM presets from the Plus Orchestral expansion, making it have 512 Presets in total (256 RAM; 256 ROM), the most possible for a Proteus module like this.

To make room for the new presets, the Demo Sequence was deleted.

Plus Orchestral Board

When the Proteus/1 released in 1989, it was stated that it could take another 4 MBs of sounds with an expansion board that would be announced at a later date, which followed with the Plus Orchestral expansion later being shown in September 1990 at an E-MU Audio Engineering Society exhibit in Los Angeles and subsequently released later that year.

A successfully upgraded Proteus/1

The Plus Orchestral expansion adds 128 new ROM presets after the main Proteus/1 sounds, making up 4MBs of samples selected from the Proteus/2. Upon successfully upgrading the module, starting up the Proteus/1 start up as a "Proteus/1+2".

The biggest omissions from the Proteus/2 are largely the horns, drums, and other sounds.

Sound Generation

Synthesis is all the same as any other E-mu Proteus module of the time, though it does not have the updated chorus parameters, as it's still based on the Proteus/1.

The Proteus/1 Plus Orchestral, and the original Plus Orchestral expansion board, feature a selection of 79 new instrument tones from the Proteus/2.

Oddities

• There seems to be a mistake in the manual, as it lists the instrument tones up to 203, when there are actually 204. The 204th instrument tone is "204 Alt. Oboe" from Proteus/2 (which appears on that module as 40 Alt. Oboe).
