Korg Prophecy

The Korg Prophecy is considered one of the earliest (mid-nineties) "virtual analog" (a.k.a. VA) synthesizers, although its synthesis capabilities went beyond many of its VA contemporaries.

Details

Along with the Korg Z1, the Korg Prophecy is a direct descendant of the ill-fated OASYS project.[3] It was a small three-octave monosynth, a pioneer of the late 1990s "return-to-analog" trend. Offering assignable knobs, a "log controller" (a mix-up of a modulation wheel and ribbon controller assembled like a "sausage") and many other control sources, it invited players to tweak and shape the sound both easily and quickly. Deep editing, however, wasn't as straightforward, because the sound engine contained no less than 13 DSP-modeled oscillator types, each one offering a large number of parameters to adjust. Some of the most used DSP models were the analog model (based on the classic osc+filter+amp scheme, although with many powerful enhancements), the VPM model (a form of FM synthesis which avoided Yamaha's FM patent) and the "physical modeling" algorithms. The latter deserves special mention. In the mid to late 1990s, it was believed that digital "physical modeling", which recreated the sound of acoustic instruments (brass, strings, woodwinds, etc.) using DSP algorithms instead of samples, would eventually replace sample-based synthesis of those instruments, because of its unprecedented realism and expressiveness. As time passed, physical modeling seemed to lose its appeal to both manufacturers (because of the cost of investigation and implementation) and final users, who complained about the realism of the models and limited polyphony. Also, more complex playing techniques were required to play the models in a convincing way. Nevertheless, the Prophecy's low cost and broad implementation of sound generation techniques earned it a significant place in synthesizer history.

Technically, the Prophecy offered one-note monophony, several effects (including distortion, wave shaping, delay/reverb and chorus/flanger), and 128 memory locations for user sound programs. No sequencer was included, but its integrated arpeggiator was a source of "instant gratification", as some magazines put it. A PCMCIA slot allowed for offline storage of patches and banks. Standard MIDI sockets, a special socket for connecting an EC5 pedal bank, a sustain pedal socket, and a pair of audio outputs occupied the rear panel.

Korg made a major breakthrough at the time, offering a low cost expansion card for Trinity users, which incorporated the whole sound engine of the Prophecy into the already powerful workstation. Gone was the arpeggiator and some minor features, but the editing was much improved through the Trinity's big touchscreen, and the workstation's effects processing was a huge improvement over the Prophecy's basic set.

A direct descendant of the Prophecy is the Korg Z1 (1997) which is the equivalent of a 12-note polyphonic Prophecy with enhanced models, more physical control, 61-note keyboard, bigger screen, 6-part multitimbrality, more presets and two powerful programmable twin arpeggiators. Among users (see user reviews of the Prophecy and Z1 in the music aficionado web site SonicState.com, and elsewhere) there is some contention as to whether the Z1 is the equal of twelve Prophecies or is lacking both sonically and cybernetically. The argument is subjective and might be considered specious.
