E-mu PK-6 Proteus Keys

E-mu PK-6 Proteus Keys Image

The new PK-6 Proteus Keys is a sleek keyboard with E-mu's Proteus 2000 sounds and features. The PK-6 comes with the Proteus's 32 MB "Composer" soundset, and additional Proteus expansion ROM soundsets can be added up to 128 MB. The sounds cover the whole spectrum of synthesizer type sounds, from real instruments to bizarre sounds and effects. The keyboard is a full 61-keys long with 16 real-time controllers. There's also 16 on-board syncable/programmable arpeggiators and the Proteus 2000's Super BEATS interactive Groove Mode. With 16 mute/enable buttons this keyboard is set for live and on the fly performances with plenty of real-time controls! Unlike the Proteus 2000 which is 128 voice polyphonic, the PK-6 has just 64 voices and only 4 audio outputs as opposed to 6 in the rack modules. The PK-6 also features multi-mode resonant filters, 24-bit DACs, and an affordable price tag!

The PK-6 is part of a new line of performance keyboards launched by E-mu that repackage their current line-up of top notch sound modules targeted at specific genres. For all purpose synthesizer, the PK-6 Proteus Keys. For HipHop and R&B, the MK-6 Mo’Phatt Keys. For techno trance and dance, the XK-6 Xtreme Keys. And Halo from Ensoniq, which is another all purpose synthesizer.

Every one of these ships with one 32 MB sound-set, but are expandable up to 128 MB via three additional slots for 32 MB expansion cards. These cards include (ranging from $249 to $395):

  • 9061: Siedlaczek Orchestra 32 MB ROM.
  • 9062: Pure Phatt 32 MB ROM - standard in Mo’Phatt, MP-7 and MK-6.
  • 9063: Beat Garden 32 MB ROM - standard in Orbit 3.
  • 9082: Protozoa 16 MB ROM - standard in Proteus 1, 2, 3.
  • 9083: Definitive B-3 32 MB ROM - standard in B-3.
  • 9084: Techno Synth Construction Yard 32 MB ROM - standard in Orbit 3.
  • 9085: Orchestral Session Vol. 1 32 MB ROM - standard in Virtuoso 2000.
  • 9086: Orchestral Session Vol. 2 32 MB ROM - standard in Virtuoso 2000.
  • 9087: World Expedition 32 MB ROM - standard in Planet Earth.
  • 9088: Sounds of the ZR featuring the Perfect Piano 32 MB ROM - standard in Ensoniq Halo.
  • 9089: X-Lead 32 MB ROM - standard in Xtreme Lead-1, XL-7 and XK-6.

With these expansion options, you could buy a PK-6, then add the sounds of the Orbit 3, XK-6, and the MP-7... or any other combinations you may want. If you like desktop synths, you can start with an MP-7 or XL-7, and then add these same expansion card options to add Proteus, Orchestral, or the new Halo sounds to them. E-mu/Ensoniq's interchangeable sound cards and a variety of keyboard/sound-module options means that there's a model out there for everybody now.

It all started when I longed to have a great new super synth, couldn't afford it sooo i got a used Kurzweil k2500s, later got a yamaha TG 500 module, then i got the EMU PK6, My desire for a brand new workstation or anything else has completely vanished. The Kurzweil used with ether the TG500 or PK6 gives me all possible sounds I'll ever need, the PK6 handles all my beats, loops and anything lacking with the Kurzweil and is great when I want to carry a light keyboard to reharsals or for my laptop studio. The PK6 is great addition for any set up if you know how to program it

I had the Proteus 2000 rack version back in the day. Paid £600 for it if I remember..... Solid piece of gear that provided all the standard sounds my analogs couldn't come up with. I picked up the PK6 on the cheap recently... previous owner had messed up the arpeggiator and thought it was broken ;) Hate the plastic case and general look, but the keybed is ok, and performance mode is where the actions at. You gotta drive the filters and add plenty of the on-board effects.... at which point it can be pleasantly surprising and aggressive. The DA's have a nice vibe too....

Hi, i'm using the Proteus VX (VST version of Proteus X). Does it make sense to buy a PK-6, or is has the Proteus VX the same preset sounds?
Thanks in advance...

Performance matrix = originality without study. Expandable--mine has the Mo'Phatt board installed. Some sounds scream "90's funk band", but is that a bad thing?
Beats mode = loops without thinking. 1 quibble: give me a dedicated tap-tempo button. Biggest complaint: with these filters, the on-board pianos could be much more responsive. Plus side: fixing that is easier than on a module. Gives good bang-for-the-buck. Yes, the casing is plastic, but more solid than the plastic Korg & Yamaha are using on their low-end synths.

Hey I just came into owning a good number of these. Anyone know what they go for on average, used?
