The first polyphonic analog synthesizer fully programmable.

The synthesizer prefigures all modern keyboards.

A good control surface with a configuration accesible.
With editing and sound effects takes a lot of fun.
The manual is clear and sufficient.


Sounds wonderful, excellent effects, filters that deformation, bass slap, a high resonance crying, a Unison mode monstrous little ignite.

The stamps of the Prophet provide real chills, goose bumps.
Ultra realistic and alive sounding completely apart.
The sound is very rich and powerful also very sharp and versatile.


I tried many other models, but the Prophet V is truly unique.
This is a Rolls Royce level aesthetics and sounds.
Its really a great, bold, rich with a beautiful surface control, large knobs turned to very heavy.
Its wooden veneer is very nice and pleasant to touch.
And an armored steel hull below.

The best sound probably comes from the Prophet 5 Rev 1, but they are horribly scarce just 182 models, and hopelessly unreliable and also very difficult to repair.

The Rev 2 and a bit more reliable, sounds great, and it can be with MIDI.

I decided for Rev. 3, a better reliability and better repair in the event, with an additional 80 patch memories for later.
And in 30 years of service in its power VCA chips changed and a bushing complete, well in some really talk about reliability.
