KORG Prophecy's on eBay

"It's not a new synth -- it's seven! Korg's amazing new Prophecy offers analogue and FM synthesis, and physical modelling, and still costs under £1000. Unsurprisingly, SOS staff have been dying to review one ever since it was unveiled at this year's Frankfurt Musik Messe. Lucky man GORDON REID won the toss...

This is the story as it was told to me... In 1987, the former Sequential Circuits design team (responsible for classics such as the Prophet 5 and Prophet VS) began working for Korg. The company immediately bundled them out of sight, locked them in a room full of computers and said "design something for us". Locks were locked, bolts were bolted, and most people forgot that they had ever existed.

Years passed. Every day somebody from Korg would shove some food and water through a hole in the door. Then, one day, there was a timorous knock from inside. Locks were unlocked and bolts were drawn. When the door was opened, a pasty-faced individual peeked out, blinked in the light, and said, "We've designed something. It's called a Wavestation". "What does it do?" asked the guys from Korg. "Well, it's sort of a wavetable synthesizer, with vector synthesis, and wave sequencing". "Not bad" said the guys from Korg. "Now get back inside and design something else".

Years passed. Every day somebody from Korg would shove some food and water through a hole in the door. Then, one day, there was another timorous knock from inside. The door was opened, and an even pastier-faced individual peeked out, blinked in the light, and said "We've designed something else". "What does it do this time?" asked the guys from Korg. "Well, it does analogue synthesis" said the pasty-faced one. "And FM. Oh yes... and physical modelling of plucked strings. And brass. And reeds. And it can be programmed to handle any new synthesis techniques that may come along in the future... and it does them all simultaneously. We've called it the Open Architecture Synthesis System, or OASYS for short."

The executives at Korg were delighted, and instead of shoving the team back into their room, bought them dinner at an expensive Japanese restaurant. But there was a problem. At £10,000, the OASYS was expensive. Very expensive. So Korg turned to the developers and said, "Sorry guys, we've got to put you back in your room. We need something cheaper, something that will appeal to the average musician. Something, to be blunt, that we can sell in the mass markets."

Months passed. Every day somebody from Korg would shove some food and water through the hole in the door. Then, quite recently, there was a knock from inside. An extremely pasty-faced individual peeked out and said, "We've done what you asked". "What does it do?" asked the guys from Korg. "Well, it does analogue synthesis" said the pasty-faced one. "And FM. Oh yes... and physical modelling of plucked strings. And brass. And reeds. And, before you shove us back in the room... it does all that for less than £1,000." Thus did the Prophecy, as they say, come to pass.

OUTSIDE AND IN

Externally, the Korg Prophecy is a light but robust 37-note monosynth with a velocity- and aftertouch-sensitive keyboard. The styling is, to my eyes, new and refreshing, although a few people have commented on its similarities to the Yamaha VL1... A 2 x 40-character backlit LCD dominates the control panel, and is surrounded by buttons to the left and right, and knobs underneath. Conventional modulation and pitch-bend wheels, plus the 'log' (a combined mod-wheel and pressure-sensitive ribbon controller), round off the package. Most people will either love it or hate it. I love it...

Round the back, you'll find the inevitable MIDI In, Out and Thru, alongside inputs for an expression pedal, an on/off (sustain) foot-switch, and a socket for an EC5 MIDI controller. This can be used for patch selection when your hands are otherwise occupied. There's also a socket for a RAM card that will store arpeggiator patterns as well as patches. And, finally, there are the stereo audio outputs.

Internally, the Prophecy is just a computer, although it boasts no fewer than five processors. Three of these are the Texas Instruments TMS57002 DSPs used in the Korg G-series effects. The other two are for housekeeping: an NEC V55 looks after the user interface, key-scanning, and display, and a Toshiba H8 (which I've never heard of) looks after the three DSPs."
