When it comes to synthesizers named PROPHET, known for their characteristic analog synth sound (even the ones with digital oscillators), it's pretty much a given that if you like synths then you're familiar with them—from the vintage ones to their modern lineup.

CASIO is well-known for its PRIVIA line of high-quality digital pianos, and for its portable keyboards with light-up keys. This time, we reviewed their new CT-X5000 model, which would fall into the high-grade keyboard category.

With the Prologue, Korg brings us a high-end polyphonic synth, the latest in their recent series of analog synthesizers which began with the monophonic Monologue and the 4-voice Minilogue.

There are two Prologue models to choose from, the 8-voice 49-key version or 16-voice 61-key model, so it's easy to select one that meets your needs. For our review we used the flagship 16-voice 61-key model.
